Congratulations #DeleteUber on Weakening an Important Source of Restraint on Trump

A couple weeks ago I was having dinner with a couple of guys who fear and despise Trump.  I told them that all the marches in the streets were not going to affect Trump's behavior one bit, though it will affect the behavior of the Congress when (and if, given the new Imperial presidency, copyright Bush and Obama) they are called on to ratify some of Trump's actions.  I told them that the biggest check on Trump, at least in the near term on issues like immigration, was going to be American corporations.  As much as the Left may not like corporations, businesses need trade and immigration and free international travel to function in the global economy and they are not going to be happy about all of Trump's planned restrictions (you could see echoes of that last night in a number of the Superbowl commercials).

So of course the Left gears up a #DeleteUber campaign because Uber didn't participate in a taxi strike at JFK protesting Trump's immigration order.  Essentially, protesters who are mad at Trump for restricting travel are mad at Uber for, uh, not restricting travel.  In the end, all the #DeleteUber folks did was force the Uber CEO to quit Trump's advisory counsel.  Congratulations Left, you managed to remove a likely voice of reason from inside the White House.

I would happily join up with the Left in opposition to a lot of Trump's actions if I wasn't so absolutely horrified at their tactics.  There is no reason, no thoughtfulness at all.  Even the media participates in this dumbing down by simply refusing to making issues clear (e.g. continuing to call the 90-day visa timeout from 7 countries a "muslim ban").  And the first person from the Left who I hear criticize the anti-free-speech violence at Berkeley will be the first.

Update:  97 tech firms team up against Trump's immigration ban.  The problem with this approach is that I am not sure the "immigration ban", which is in fact a 90-day pause in issuing visas to folks from 7 countries, is actually illegal under current law and precedent.   Obama did something similar with Iraq at one point.   But I am happy to see them taking a shot at it -- in my mind a single person should not have this much power.  By the way, Amazon and Tesla did not sign, in part because their leaders still sit on Trump's advisory board.  The latter strikes me as a reasonable strategy, but I wonder how long the Left will allow them to remain inside the tent.


Global Temperature Update

I just updated my climate presentation with data through December of 2016, so given "hottest year evah" claims, I thought I would give a brief update with the data that the media seldom ever provides.  This is only a small part of my presentation, which I will reproduce for Youtube soon (though you can see it here at Claremont-McKenna).  In this post I will address four questions:

  • Is the world still warming?
  • Is global warming accelerating?
  • Is global warming "worse than expected"?
  • Coyote, How Is Your Temperature Prediction Model Doing?

Is the world still warming:  Yes

We will use two data sets.  The first is the land surface data set from the Hadley Center in England, the primary data set used by the IPCC.  Rather than average world absolute temperature, all these charts show the variation or "anomaly" of that absolute temperature from some historical average (the zero point of which is arbitrary).  The theory is that it is easier and more accurate to aggregate anomalies across the globe than it is to average the absolute temperature.  In all my temperature charts, unless otherwise noted, the dark blue is the monthly data and the orange is a centered 5-year moving average.

You can see the El Nino / PDO-driven spike last year.  Ocean cycles like El Nino are complicated, but in short, oceans hold an order of magnitude or two more heat than the atmosphere.  There are decadal cycles where oceans will liberate heat from their depths into the atmosphere, creating surface warming, and cycles where oceans bury more heat, cooling the surface.

The other major method for aggregating global temperatures is using satellites.  I use the data from University of Alabama, Huntsville.

On this scale, the el nino peaks in 1999 and 2017 are quite obvious.  Which method, surface or satellites, gets a better result is a matter of debate.  Satellites are able to measure a larger area, but are not actually measuring the surface, they are measuring temperatures in the lower tropospehere (the troposphere's depth varies but ranges from the surface to 5-12 miles above the surface).  However, since most climate models and the IPCC show man-made warming being greatest in the lower troposphere, it seems a good place to measure.  Surface temperature records, on the other hand, are measuring exactly where we live, but can be widely spaced and are subject to a variety of biases, such as the urban heat island effect.  The station below in Tucson, located in a parking lot and surrounded by buildings, was an official part of the global warming record until my picture became widely circulated and embarrassed them in to closing it.

This argument about dueling data sets goes on constantly, and I have not even mentioned the issues of manual adjustments in the surface data set that are nearly the size of the entire global warming signal.  But we will leave these all aside with the observation that all data sources show a global warming trend.

Is Global Warming Accelerating?  No

Go into google and search "global warming accelerating".  Or just click that link.  There are a half-million results about global warming accelerating.  Heck, Google even has one of those "fact" boxes at the top that say it is:

It is interesting by the way that Google is using political advocacy groups for its "facts" nowadays.

Anyway, if global warming is so obviously accelerating that Google can list it as a fact at the top of its search page, it should be obvious from the data, right?  Well let's look.  First, here is the satellite data since I honestly believe it to be of higher quality than the surface records:

This is what I call the cherry-picking chart.  Everyone can find a peak for one end of their time scale and a valley for the other and create whatever story they want.  In economic analysis, to deal with the noise and cyclicality, one will sometimes see economic growth measured peak-to-peak, meaning from cyclical peak to the next cyclical peak, as a simple way to filter out some of the cyclicality.  I have done the same here, taking my time period as about 18 years from the peak of the 1999 El Nino to 2017 and the peak of the recent El Nino.  The exact data used for the trend is show in darker blue.  You can decide if I have been fair.

The result for this time period is a Nino to Nino warming trend of 0.11C.  Now let's look at the years before this

So the trend for 36 years is 1.2C per century but the trend for the last half of this is just 0.11C.  That does not look like acceleration to me.  One might argue that it may again accelerate in the future, but I cannot see how so many people blithely treat it as a fact that global warming has been accelerating when it clearly has not.  But maybe its just because I picked those darn satellites.  Maybe the surface temperatures show acceleration?

Nope.  Though the slow down is less dramatic, the surface temperature data never-the-less shows the same total lack of acceleration.

Is Global Warming "Worse Than Expected"?  No

The other meme one hears a lot is that global warming is "worse than expected".  Again, try the google search I linked.  Even more results, over a million this time.

To tackle this one, we have to figure out what was "expected".  Al Gore had his crazy forecasts in his movie.  One sees all kinds of apocalyptic forecasts in the media.  The IPCC has forecasts, but it tends to change them every five years and seldom goes back and revisits them, so those are hard to use.  But we have one from James Hansen, often called the father of global warming and Al Gore's mentor, from way back in 1988.  His seminal testimony in that year in front of Congress really put man-made global warming on the political map.  Here is the forecast he presented:

Unfortunately, in his scenarios, he was moving two different variables (CO2 levels and volcanoes) so it is hard to tell which one applies best to the actual history since then, but we are almost certainly between his A and B forecasts.  A lot of folks have spent time trying to compare actual temperatures to these lines, but it is very hard.  The historical temperature record Hansen was using has been manually adjusted several times since, so the historical data does not match, and it is hard to get the right zero point.  But we can eliminate the centering issues altogether if we just look at slopes -- that is all we really care about anyway.  So I have reproduced Hanson's data in the chart on the left and calculated the warming slopes in his forecast:

As it turns out, it really does not matter whether we choose the A or B scenario from Hansen, because both have about the same slope -- between 2.8C and 3.1C per century of warming from 1986 (which appears to be the actual zero date of Hansen's forecast) and today.  Compare this to 1.8C of actual warming in the surface temperature record for this same period, and 1.2C in the satellite record.  While we have seen warming, it is well under the rates predicted by Hansen.

This is a consistent result to what the IPCC found in their last assessment when they evaluated past forecasts.  The colored areas are the IPCC forecast ranges from past forecasts, the grey area was the error bar (the IPCC is a bit inconsistent when it shows error bars, including error bands seemingly only when it helps their case).  The IPCC came to the same result as I did above:   that warming had continued but was well under the pace that was "expected" form past forecasts.

By the way, the reason that many people may think that global warming is accelerating is because media mentions of global warming and severe weather events has been accelerating, leaving the impression that things are changing faster than they truly are.  I wrote an article about this effect here at Forbes.  In that I began:

The media has two bad habits that make it virtually impossible for consumers of, say, television news to get a good understanding of trends

  1. They highlight events in the tail ends of the normal distribution and authoritatively declare that these data points represent some sort of trend or shift in the mean
  2. They mistake increases in their own coverage of certain phenomenon for an increase in the frequency of the phenomenon itself.

Coyote, How Is Your Temperature Prediction Model Doing?  Great, thanks for asking

Ten years ago, purely for fun, I attempted to model past temperatures using only three inputs:  A decadal cyclical sin wave, a long-term natural warming trend out of the little ice age (of 0.36 C per century), and a man-made warming trend really kicking in around 1950 (of 0.5C per century).  I used this regression as an attribution model, to see how much of past warming might be due to man (I concluded about half of 20th century warming may be due to manmade effects).  But I keep running it to test its accuracy, again just for fun, as a predictive tool.  Here is where we are as of December of 2016 (in this case the orange line is my forecast line):

Still hanging in there:  Despite the "hottest year evah" news, temperatures in December were exactly on my prediction line.  Here is the same forecast with the 5-year centered moving average added in light blue:

Does The Left Know How To Make An Argument Not Based On Racism? The Trouble With the Left's Critique of Trump

As I predicted in my letter to the Princeton University President last year, two decades of living in university monocultures and political echo chambers, combined with a one-track focus on social justice, seems to have left the political Left with no ability to engage in rational opposition politics.

The Golden Globe Awards were a magnificent example.  I presume that many of these actors are reasonably intelligent people.  And they are obviously upset and worried about Donald Trump's election to President.  But they can't express anything beyond their fear and loathing.  They can't articulate what specifically worries them, and when they do articulate something specific - e.g "this may be the last Golden Globes Awards" - it is silly and illogical.

Perhaps worse, these critiques of Trump are, IMO, focusing on all the wrong things and sucking the oxygen out of the room for more relevant criticism.  The Hollywood types all seemed terrified that they and their industry are going to somehow fall victims to government authoritarianism.  At some level I guess this makes sense -- when the Left was in power, they used their power to hammer industries they did not like (eg energy) and thus expect that the Right will do the same once they are in power.  But Trump is a New York social liberal who is a part of the entertainment industry.   While I confess that one of the problems with Trump is that he is wildly unpredictable, Hollywood is an unlikely target, at least until they just  went on TV and begged to be one.

An even better example of focusing on all the wrong problems is the confirmation hearings for Jeff Sessions.  If you read pretty much any of the media, you will be left with the impression that the main issue with Sessions is whether he is a racist, or at least whether he is sufficiently sensitive to race issues.  But this is a complete diversion of attention from Sessions' true issues.  I am not sure what is in his heart on race, but his track record on race seems to be pretty clean.  His problems are in other directions -- he is an aggressive drug warrior, a fan of asset forfeiture, and a proponent of Federal over local power.  As just one example of problems we may face with an AG Sessions, states that have legalized marijuana may find the Feds pursuing drug enforcement actions on Federal marijuana charges.

Why haven't we heard any of these concerns?  Because the freaking Left is no longer capable of making any public argument that is not based on race or gender.  Or more accurately, the folks on the Left who see every single issue as a race and gender issue are getting all the air time and taking it away from more important (in this case) issues.    The SJW's are going to scream race, race, race at the Sessions nomination, and since there does not seem to be any smoking gun there, they are going to fail.  And Sessions will be confirmed without any of his real illiberal issues coming out in the public discussion about him.

I have said this before about Left and Right and their different approaches to politics.  The Left is great at getting attention on an issue.  Think of BLM and their protests and disruption tactics -- they had everyone's attention.  But they went nowhere on policy.  I challenge you to list the 5 or 10 policy goals of BLM (they actually had a good set once, but abandoned them).  The Left is great at expressing anger and dismay and frustration and outrage, but terrible about thoughtfully taking steps to fix it.  The Right on the other hand is great at working (plodding, really) in the background on policy issues, often at the local level.  ALEC is a great example, building a body of model legislation, working in groups around the country to try to implement these models.  But they absolutely suck at generating emotion and excitement around key issues (except maybe for wars and in abortion protests).  The only example I can really think of is the Tea Party, and (despite how the media tried to portray it) the Tea Party was extraordinarily well-behaved and moderate when compared to protest movements on the Left.

Trump has an enormous number of problems in his policy goals, not the least of which is his wealth-destroying, job-destroying ideas on trade nationalism.   But all we get on trade are a few lone voices who have the patience to keep refuting the same bad arguments (thanks Don Boudreaux and Mark Perry) and instead we get a women's march to protest the Republican who, among the last season's Presidential candidates, has historically been the furthest to the Left on women's issues.    It is going to be a long four years, even longer if the Left can't figure out how to mount a reasonable opposition.

Postscript:  All of this is without even mentioning how the Left's over-the-top disruption tactics seem to just feed Trump's energy.  At some point, Hercules figured out that cutting heads off the hydra was only making things worse and switched tactics.  If only I could be so confident about the Left.

I Was Right About the December Surprise, But For the Wrong Reasons

I have observed in the past that the media will run negative pieces about legislation they favor, but only after the legislation is passed and the information is not longer useful to the debate.  I suppose they do this to retroactively create a paper trail for being even-handed.  So I hypothesized that we might see a December surprise once Hillary won, raising issues about her more forthrightly than they were willing to before the election.

Well, I was sortof right.  We are seeing a December surprise -- the silly Russian hacking story being pushed by the Clinton campaign and the White House -- but for completely different reasons.   These stories are clearly to try to de-legitimize Trump's election, either just as general battle-space preparation or more specifically ahead of the Electoral College vote.

By the way, speaking of fake news, it strikes me there is an interesting bait and switch in how this story is presented.  The story itself is about the appropriation and publication of the emails of Democratic insiders.  To my knowledge, no one has claimed the emails have been altered or faked, so one could argue that most of the damage is self-inflicted on Democrats -- if they had not been writing about inciting violence at Trump rallies, there would be nothing salacious to leak.

But the media shorthands all this as just "hacking" which I suspect many low information voters think refers to actually altering vote tabulations.  Certainly this is the assumption that Jill Stein and all the suckers who donated to her money-hole recount effort ran with.  But of course there is zero evidence of this and it is almost impossible to imagine happening in any kind of wholesale manner.  But I think that some in the media and many in the Democrat camp are purposely throwing around the "hacking" term in the hopes that people will get this false impression.

Postscript:  I have a new standard we should apply to any government regulatory effort aimed at a private company selling a product or service thought to be fraudulent:  No private individual can be prosecuted for selling any product or service that is less of a scam than Jill Stein's recount eff0rt (which, oh wait, may get spent on something else, anything else they want).   Ordinary people are being suckered into giving money to this on completely false, really absurd, principles.  It infuriates me when politicians get all pious about, say, Exxon misleading the public about global warming when they sell crap like this.  At least when I pay my $3 to Exxon, I get a gallon of gas that actually runs my car as promised.  What will any of these donors get from Stein's effort?

Politicians Are Going to Use "Fake News" Panic as A Wedge to Enhance Censorship

This is simply a terrible idea and demonstrates the point I made after the last election, that "fake news" is the new "hate speech" -- in other words, an ill-defined, amorphous term that will be the excuse for censorship.  Every politician thinks that every criticism of themselves is "fake news".   Note the absolute relish with which the millennial Endgadget author greets this awful idea:

Fake news and hate speech are sadly unavoidable on social media, but that might change soon... in Germany, anyway. Late last week, Thomas Oppermann — chairman of the German Social Democratic Party — proposed a stringent law meant to hold companies like Facebook responsible when fake news makes the rounds. As reported by Der Spiegel(and translated by Deusche Well), Oppermann's plan would require Facebook to actively combat fake news all day, everyday. Here's the fascinating bit: if a fake news item pops up and Facebook can't address it within 24 hours, it would be subject to a €500,000 (or $522,575) for each post left untouched.

Oh, it gets better. Facebook and other "market-dominating platforms" would be required to to have teams in Germany dedicated to fielding reports of fake news and hate-filled posts. Fortunately for Oppermann — and German web users, most likely — the push to penalize companies for letting false, misleading or malicious content run wild has received plenty of support from the other major party in German politics, too. The country's Christian Democratic Union hates all of that stuff just as much, prompting one senior party member to promise definitive action "at the beginning of next year." The CDU has also proposed legislation (with backing from Chancellor Angela Merkel, no less) that would make it illegal to post fake news entirely.

I Hate to Repeat Myself, But Trump Did Not Win: Clinton Lost

This article by Damon Linker totally mirrors my take on this election -- a competent Democratic candidate without Clinton's many flaws should have wiped the floor with Trump.  Biden would have won, I am absolutely convinced.  Anyway, I liked this bit from Linker:

Most of all, I don't want to hear about how unfairly Clinton was treated by the media. In comparison to whom? All the other candidates who've run for president while under criminal investigation by the FBI? (Maybe that substantial handicap should have overridden the party's presumption that she was owed the nomination because it was "her turn.") Or do you mean, instead, that she was treated badly in comparison to her opponent? Really? You mean the one whose 24/7 media coverage was overwhelmingly, relentlessly negative in tone and content? Either way, a halfway competent campaign should have been able to take advantage of the great good fortune of running against Donald J. Trump and left him bleeding in the ditch.

I am exhausted with folks talking about some fundamental political shift to a white male resurgence, or whatever.  There was no shift.  Trump got about the same number of votes as Romney and McCain.  He won no more white male votes than those guys and if anything performed better than them in traditional Democratic categories like single women and blacks.  The reason Trump won is because Clinton had 10 million fewer votes than Obama had in his first win.  Traditional Democratic supporters were unenthusiastic about Clinton and stayed home.

Um, What Part of "Off the Record" Doen't Anyone Understand

I don't know if this is coming from the media folks present in the room or the Trump side, but the New York Post has a pretty complete record of Trump's "off the record" meeting with the media.  Yet another reason not to trust the media -- they don't follow their own rules.

The Term "Fake News" Joins "Hate Speech" As A New Tool for Ideological Speech Suppresion

The term "hate speech" has become a useful tool for speech suppression, mostly from the Left side of the political aisle.  The reason it is such a dangerous term for free speech is that there is no useful definition of hate speech, meaning that in practice it often comes to mean, "confrontational speech that I disagree with."   I think most of us would agree that saying, "all black men should be lynched" is unambiguously hateful.  But what about saying something like "African Americans need to come to terms with the high rate of black on black violence."  Or even, "President Obama plays too much golf."   I would call both the latter statements opinions that, even if wrong, reasonably fit within the acceptable bounds of public discourse, but both have been called hate speech and racist.

The Left's new tool for speech suppression appears to be the term "fake news."  Certainly a news story that says, "American actually has 57 states" would be considered by most to be fake.  We understand (or most of us outside places like the New York Times, which still seems to get fooled) that sites like the Onion are fake.   But, as I suspected the very first time I heard the term, "fake news" also seems to be defined as "political sites with which I disagree."  Via Reason:

But Zimdars' list is awful. It includes not just fake or parody sites; it includes sites with heavily ideological slants like Breitbart,, Liberty Unyielding, and Red State. These are not "fake news" sites. They are blogs that—much like Reason—have a mix of opinion and news content designed to advance a particular point of view. Red State has linked to pieces from Reason on multiple occasions, and years ago I wrote a guest commentary for Breitbart attempting to make a conservative case to support gay marriage recognition....

Reporting on the alleged impact of fake news on the election is itself full of problems. BuzzFeed investigated how well the top "fake" election news stories performed on Facebook compared to the top "real" election news stories. The fake stories had more "engagement" on Facebook than stories from mainstream media outlets. There's basic problems with this comparison—engagement doesn't mean that people read the stories or even believed them (I know anecdotally that when a fake news story shows up in my feed, the "engagement" is often people pointing out that the story is fake).

There's also a problem when you look at the top stories from mainstream media outlets—they tend toward ideologically supported opinion pieces as well. Tim Carney over at The Washington Examinernoted that two of the top three stories are essentially opinion pieces:

Here's the top "Real News" stories: "Trump's history of corruption is mind-boggling. So why is Clinton supposedly the corrupt one?" As the headline suggests, this is a liberal opinion piece, complaining that the media doesn't report enough on Trump's scandals.

No. 2 is "Stop Pretending You Don't Know Why People Hate Hillary Clinton." This is a rambling screed claiming that people only dislike Clinton because she is a woman.

So in an environment where "fake news" is policed by third parties that rely on expert analysis, we could see ideologically driven posts from outlets censored entirely because they're lesser known or smaller, while larger news sites get a pass on spreading heavily ideological opinion pieces. So a decision by Facebook to censor "fake news" would heavily weigh in favor of the more mainstream and "powerful" traditional media outlets.

The lack of having a voice in the media is what caused smaller online ideology-based sites to crop up in the first place. Feldman noted that he's already removed some sites that he believes have been included "unfairly" in Zimdars' list. His extension also doesn't block access to any sites in any event. It just produces a pop-up warning.

Tellingly, in a quick scan of the sites, I don't see any major sites of the Left, while I see many from the Right (though Zero Hedge is on the list and writes from both the Left and the Right).   Daily Kos anyone?  There are conspiracy sites on the list but none that I see peddle conspiracies (e.g. 9/11 trutherism) of the Left.

This is yet another effort to impose ideological censorship but make it feel like it is following some sort of neutral criteria.

Update on My Letter to Princeton

Part of what I wrote to Princeton:

left-leaning kids ... today can sail through 16 years of education without ever encountering a contrary point of view. Ironically, it is kids on the Left who are being let down the most, raised intellectually as the equivalent of gazelles in a petting zoo rather than wild on the Serengeti.

Princeton gazelle student writing in the Daily Princetonian:

In the morning, I woke up to a New York Times news alert and social media feeds filled with disappointment. The United States had democratically elected a man who, among so many other despicable qualities and policies, is accused of and boasts about committing sexual assault. As a woman passionate about gender equality, women’s leadership, and ending sexual violence; as someone dedicated to the Clinton campaign and ready to make history; and, quite frankly, as a human being, I didn’t know how to process this. I still don’t. I felt for my friends and anyone who feels that this result puts their safety and their loved ones’ safety at risk, acknowledging that I am not the person this outcome will affect the most.

I didn’t leave my room Wednesday morning. I sat and sobbed and I still have the tissues all over my floor to prove it. When I absolutely had to get up for class, I put on my “Dare to say the F-word: Feminism” t-shirt and my “A woman belongs in the House and the Senate” sweatshirt to make myself feel stronger. Still crying, I left my room.

After hearing the election results, I had expected that the vandal would have torn down my angry note or left some snide comment. To my surprise, it was still there, and people had left supportive notes beside it. I have no idea whether the vandal is a Trump supporter or a misguided prankster unable to fathom the negative impact that a Trump presidency will have on so many people. But I know that the love and kindness others anonymously left gave me the support I needed Wednesday morning.

In every election since I was about 18 years old, I woke up on the day after the election to a President-elect I did not support, one who championed policies I thought to be misguided or even dangerous.   But I had the mental health to go on with my life;  and I had the knowledge, from a quality western history education (which no longer seems to be taught in high school or at Princeton), that our government was set up to be relatively robust to bad presidents; and I had the understanding, because I ate and drank and went to class and lived with many other students with whom I disagreed (rather than hiding in rubber room safe spaces created by my tribe), that supporters of other political parties were not demons, but were good and well-intentioned people with whom I disagreed.

News Selection Bias

When some sort of "bad" phenomenon is experiencing a random peak, stories about this peak flood the media.  When the same "bad" phenomenon has an extraordinarily quiet year, there are no stories in the media.  This (mostly) innocuous media habit (based on their incentives) creates the impression among average folks that the "bad" phenomenon is on the rise, even when there is no such trend.

Case in point: tornadoes.  How many stories have you seen this year about what may well be a record low year for US tornadoes?

Postscript: By the way, some may see the "inflation-adjusted" term in the heading of the chart and think that is a joke, but there is a real adjustment required. Today we have doppler radar and storm chasers and all sorts of other tornado detection tools that did not exist in, say, 1950. So tornado counts in 1950 are known to understate actual counts we would get today and thus can't be compared directly. Since we did not miss many of the larger tornadoes in 1950, we can adjust the smaller numbers based on the larger numbers. This is a well-known effect and an absolutely necessary adjustment, though Al Gore managed to completely fail to do so when he discussed tornadoes in An Inconvenient Truth. Which is why the movie got the Peace prize, not a science prize, from the crazy folks in Oslo.

Does My Generation Have More Tolerance for Spouses Who Don't Agree Politically?

Coming out of voting today, I met two different couples who I know who both said the same thing to me:  "we cancelled each other out".  Meaning, I think, that the husband and wife voted differently in key elections.  I know this is also true of my wife and I.  Which leads me to wonder if there is a generational difference in toleration for spouses with different political views, or if (as is often the case) nothing is really changing on this and the examples given in the media of intolerant millennials who won't socialize with people who don't pass various political litmus tests are just that, isolated examples.

Speaking of which, I took my daughter to vote for the first time today.  She was pretty excited, and planned her outfit in advance.


She asked me why I was not wearing my "I voted" sticker.  I told her that it made me feel like a sucker.  She told me that she had clearly come to vote her first time with the wrong person, and should have found a doe-eyed idealist.

The Higher Education Monoculture

I have written before that many universities have focused on creating true diversity of skin pigments and reproductive plumbing among their students but in their primary world of ideas, have created an intellectual monoculture.  If you don't believe it, check out this quote from a Yale dean in the Yale Daily News.

Despite ongoing campus discussions about free speech, Yale remains deeply unwelcoming to students with conservative political beliefs, according to a News survey distributed earlier this month.

Nearly 75 percent of 2,054 respondents who completed the survey — representing views across the political spectrum — said they believe Yale does not provide a welcoming environment for conservative students to share their opinions on political issues. Among the 11.86 percent of respondents who described themselves as either “conservative” or “very conservative,” the numbers are even starker: Nearly 95 percent said the Yale community does not welcome their opinions. About two-thirds of respondents who described themselves as “liberal” or “very liberal” said Yale is not welcoming to conservative students.


By contrast, more than 98 percent of respondents said Yale is welcoming to students with liberal beliefs. And among students who described themselves as “liberal” or “very liberal,” 85 percent said they are “comfortable” or “very comfortable” sharing their political views in campus discussions.

In an interview with the News, Yale College Dean Jonathan Holloway said the results of the survey were lamentable but unsurprising. Holloway attributed conservative students’ discomfort at sharing their views partly to the pervasiveness of social media.

“So much of your generation’s world is managed through smart phones. There’s no margin anymore for saying something stupid,” Holloway said. “People have been saying dumb things forever, but when I was your age word of mouth would take a while. Now it’s instantaneous, now context is stripped away.

So the reason Conservatives have a problem at Yale, according to the Yale administration, is that Yale people don't tolerate folks who are stupid.  LOL.  The Dean later tried to back away from this statement, arguing that he did not mean Conservatives said stupid things, but his comments don't make any sense in any other context.

The institution is certainly hurt by this sort of narrow-mindedness.  It is more of a mixed bag for students.  While Conservatives are certainly frustrated they are frequently not allowed to bring speakers from their side of political issues to campus, there is potentially a silver lining.  As I wrote previously in my letter to Princeton:

I suppose I should confess that this has one silver lining for my family. My son just graduated Amherst College, and as a libertarian he never had a professor who held similar views. This means that he was constantly challenged to defend his positions with faculty and students who at a minimum disagreed, and in certain cases considered him to be a pariah. In my mind, he likely got a better education than left-leaning kids who today can sail through 16 years of education without ever encountering a contrary point of view. Ironically, it is kids on the Left who are being let down the most, raised intellectually as the equivalent of gazelles in a petting zoo rather than wild on the Serengeti,.

December Surprise

I have written a number of times in the past that the media is often reluctant to publish potential issues about pending legislation that they support -- but, once the legislation is passed, the articles about problems with the legislation or potential unintended consequences soon come out, when it is too late to affect the legislative process.  My guess is that these media outlets want the legislation to pass, but they want to cover their butts in the future, so they can say "see, we discussed the potential downsides -- we are even-handed."

I don't know if this practice spills over from legislation to elections, but if it does, we should see the hard-hitting articles about Hillary Clinton sometime in December.

EEK! Those Power Plants Are Spewing Water Into the Atmosphere!

Yet another media article on CO2 illustrated with steam plumes

Postscript:  This is even funnier, potentially, since given the size and design of those cooling towers, this is very likely a nuclear plant, which of course has no CO2 emissions at all.

Postscript #2:  I tried a reverse image search to try to confirm my guess this is a nuclear plant.  This is what Google returned:


That will give you some idea how often the media has used this stock image of water vapor to illustrate CO2 articles.

Guide for Politicians: How to Lie in the 21st Century

Lying is an old, old skill among politicians.  What is new in the 21st century is that with the advent of the Internet and alternative media, it is much more likely for a politician to get caught publicly in a lie.  Based on my observations over the last year of the political-media process, here is my brief guide for politicians on how to lie, or more accurately, how to manage affairs when caught lying.

First, there must be a lie, as represented by this chart:

21st century lying

There is some underlying truth out there (shown with the blue dot), and given the squishiness of the English language at times, there are a variety of ways that truth could reasonably be restated, shown by the blue circle around it.  On the left we will assume someone has lied or made an incorrect statement about that truth, and again there is a reasonable range of meanings around that untrue statement, shown by the red circle around it.  Note that the reasonable range of meanings for the original statement do not encompass the truth.

So what happens next?  Well, one possibility is that no one calls you on the untruth.  Congratulations, you are done!  The other possibility, though, is that some crazy dude on the Internet found a cell phone video embedded in a World of Warcraft chat room that reveals you did not tell the truth.  So what now?

The thing to remember at this point is that you have two assets.  First, you presumably have supporters.  Your supporters want to believe you.  They are looking for some explanation or statement from you that is even minimally convincing, and they are ready to trumpet that explanation like it is the Word of God to the rest of the world.

Your second asset is the media.  Your original lie was maybe a week ago.  That is the Jurassic Period for the media.  They don't have the staff to track down what is happening today, much less go back over something from a week ago.

Taking these two assets in mind, you are going to restate your original untrue statement, as so in orange:


The key for this to work is to make sure the range of meanings from your original statement and the range of possible meanings from your new statement overlap.  By doing so, you haven't admitted to lying or changed your position -- you have clarified.  Cognitive dissonance in your supporters will cause their brains to immediately substitute all instances of your first statement in their memories with your new restatement.

OK, but what happens when that dude in his pajamas does it again, and claims you are still lying with your new restatement.  What do you do?  Same thing as last time: another restatement.  If necessary, you will keep restating until the range of meanings of your restatement overlaps with the truth:


Yay!  You are done.  If you really want to win the news cycle, take your final restatement to Politifact and get them to rate it as mostly true.   Sure, some crazies on the other side of the aisle are going to be screaming that the ultimate truth does not at all resemble your original statement, but just claim that they are dredging up old news and that it has already been settled.  For extra points, if you are a female and/or the member of an ethnic minority, claim discrimination, saying that the opposition is driven by racism, misogyny, etc.

I think this is all clearer with an example.  So let's take the case of Philander J. Donkeyphant, who is running for reelection.  Phil decides to lie about the vehicle he was driving yesterday.  Why does he lie?  Who knows, but Phil is a successful politician and senior government official and therefore one of our betters and let's not question his tactics.   So let's see how his lie plays out:

Lie:  I drove a red car yesterday

Soon, Philander has a problem.  Some crazy lady finds a traffic camera video and proves no red car drove by that could have been Philander's.  So Phil is forced into his first restatement:

First Restatement:  I was driving a deep-red pickup truck

A bit of a stretch but we can't really call it changing his story, since many folks might refer to the family car and actually be talking about a pickup truck.  And the "deep red" comment seems downright helpful, trying to provide more detail.  But wouldn't you know it, that lady can't find any deep red pickup trucks on camera.  So Phil moves to his second restatement:

Second Restatement:  I was driving a violet truck.

Again, a bit of a stretch, but violet is not far from deep-red.  He has dropped the detail of it being a pickup truck, now it is just a truck, but still arguably consistent with his immediately previous statement.

Finally, our annoying blogger-lady finds Philander and his vehicle on a video.  It turns out:

Truth:  He was driving a purple 18-wheeler.

When shown the video, old Phil says, "Sure, that's what I said.  A violet truck.  Obviously my opposition has nothing better to do than make stupid issues like this out of nothing.  Politifact confirms that "violet truck" is a truthful way to describe a "purple 18-wheeler" so the issue is closed.

Perfect Example of Blaming the Free Market for Government Interventions

Hillary Clinton, along with many politicians and most of the media, is arguing that the recent large price increase in Epipens is some sort of market failure requiring government intervention to solve.

Democratic presidential nominee Hillary Clinton jumped into the fray over rapid price increases for the EpiPen, a life-saving injection for people who are having severe allergic reactions.

Mrs. Clinton called the recent price hikes of the EpiPen “outrageous, and just the latest example of a company taking advantage of its consumers.”

In a written statement calling for Mylan to scale back EpiPen prices, Clinton added, “It’s wrong when drug companies put profits ahead of patients, raising prices without justifying the value behind them.”

Why aren't similar government interventions required to curb greed in the pricing of paint, or tacos, or toilet paper?  Because the markets are allowed to operate and competitors know that if they raise prices too high, their existing competitors will take sales from them, and new competitors may enter the market.  The reason this is not happening with Epipens is that the Federal government blocks other companies from competing with Mylan for the Epipen business with a tortuous and expensive and pointless regulatory process (perhaps given even more teeth because Mylan's CEO has a lot of political pull).  The MSNBC article fails to even mention why Mylan has no competition, and in fact essentially assumes that Epipens are a natural monopoly and should be treated as such, despite the fact that there are 3 or 4 different companies that have tried (and failed) to clear the regulatory process over the last several years with competing products.  Perhaps these other companies would have been smarter to appoint a Senator's daughter to a senior management position.

Hillary Clinton is proposing a dumb government intervention to try to fix some of the symptoms of a previous dumb government intervention.  It would be far better to work the root cause instead.

Postscript:  Credit Vox with the stupid argument of the day:  

Other countries do this for drugs and medical care – but not other products, like phones or cars – because of something fundamentally unique about medication: If consumers can’t afford the product, they could have worse odds of living. In some cases, they face quite certain odds of dying. So most governments have decided that keeping these products affordable is a good reason to introduce more government regulation.

Hmm, let me pick a slightly different example -- food.  I will substitute that into the Vox comment.   I think it would be perfectly correct to say that there is not price regulation of food in the US, and that "If consumers can’t afford [food], they could have worse odds of living. In some cases, they face quite certain odds of dying."  In fact, the best place today to face high odds of dying due to lack of food is Venezuela, where the government heavily regulates food prices in the way Vox wished to regulate drugs prices.

Being A Victim Apparently Has More Status Now Than Being A Gold Medal Winner -- Ryan Lochte Channels "Jackie"

There appears to be no rational way to explain Ryan Lochte's bizarre need to make up a story about being the victim of an armed robbery.  The media seems to be pushing the notion that he made up the story to cover up his own vandalism at a gas station, but that makes zero sense.  He had already defused the vandalism incident with a payment of cash to the station owner.  The rational response would be to just shut up about the whole thing and let it be forgotten.

But instead, he purposely made a big deal about the incident, switching around the facts until he was a victim of an armed assault by men posing as police officers, up to and including harrowing details of a cocked gun being jammed into his forehead.  The incident, likely ignored otherwise, suddenly became a BIG DEAL and subsequent investigation (including multiple video sources) showed Lochte to be a bald-faced liar.

The only way I can explain Lochte's motivation is to equate it with the lies by "Jackie" at the University of Virginia, whose claims of being gang-raped as published in the Rolling Stone turned out to be total fabrications.  Like Lochte, she dressed up the story with horrifying details, such as being thrown down and raped on a floor covered in broken glass.  The only real difference I can see, in fact, between Lochte and Jackie  is that the media still protects Jackie (via anonymity) from well-deserved humiliation for her lies while it is piling on Lochte.

I can sort of understand Jackie's motivation -- she was by all accounts a frustrated, perhaps disturbed, certainly lonely young woman who was likely looking for some way to dramatically change her life.  But Lochte?  Ryan Lochte has won multiple Olympic medals, historically in the sports world a marker of the highest possible status.  But in today's world, Lochte viewed victimhood as even higher status.

Update:  This is probably the fairest account of the whole incident.

Uncertainty Intervals and the Olympics

If I had to pick one topic or way of thinking that engineers and scientists have developed but other folks are often entirely unfamiliar with, I might pick the related ideas of error, uncertainty, and significance.  A good science or engineering education will spend a lot of time on assessing the error bars for any measurement, understanding how those errors propagate through a calculation, and determining which digits of an answer are significant and which ones are, as the British might say, just wanking.

It is quite usual to see examples of the media getting notions of error and significance wrong.  But yesterday I saw a story where someone actually dusted these tools off and explained why the Olympics don't time events to the millionths of a second, despite clocks that are supposedly that accurate:

Modern timing systems are capable of measuring down to the millionth of a second—so why doesn’t FINA, the world swimming governing body, increase its timing precision by adding thousandths-of-seconds?

As it turns out, FINA used to. In 1972, Sweden’s Gunnar Larsson beat American Tim McKee in the 400m individual medley by 0.002 seconds. That finish led the governing body to eliminate timing by a significant digit. But why?

In a 50 meter Olympic pool, at the current men’s world record 50m pace, a thousandth-of-a-second constitutes 2.39 millimeters of travel. FINA pool dimension regulations allow a tolerance of 3 centimeters in each lane, more than ten times that amount. Could you time swimmers to a thousandth-of-a-second? Sure, but you couldn’t guarantee the winning swimmer didn’t have a thousandth-of-a-second-shorter course to swim. (Attempting to construct a concrete pool to any tighter a tolerance is nearly impossible; the effective length of a pool can change depending on the ambient temperature, the water temperature, and even whether or not there are people in the pool itself.)

By this, even timing to the hundredth of a second is not significant.  And all this is even before talk of currents in the Olympic pool distorting times.

Wow, With This Level of Understanding of How Government Works, It's Hard To Believe We Struggle to Have Meaningful Public Discourse

I don't have any particular comment on the Supreme Court decision in Voisine v. United States, but I have to highlight the headline that was just shared with me on Facebook:

Another Big Win: SCOTUS Just Banned Domestic Abusers From Owning Firearms

Um, pretty sure that is not what happened.

First, convicted domestic abusers generally are already banned from owning firearms.

Second, I am fairly certain that SCOTUS did not ban anything (not surprising since they don't have a Constitutional power to ban anything).  There was some legal uncertainty in the definitions of certain terms in a law (passed by Congress and signed by the President) that restricted gun ownership based on certain crimes.  This dispute over the meaning of these terms bounced back and forth in the courts until the Supreme Court took the case and provided the final word on how the terms should be interpreted by the judicial system.

This decision strikes me as a pretty routine sort of legal result fixing a niche issue in the interpretation of terms of the law.  How niche?  Well apparently Voisine was convicted (multiple times) of "“intentionally, knowingly, or recklessly” hurting his girlfriend.  The facts of the case made it pretty clear that he was beating on her on purpose, but he argued that due to the "or" in the wording of the crime he was convicted of, as far as the law is concerned he might have only been convicted of recklessness which shouldn't be covered under the gun ownership ban.  Really, this silliness should never have reached the Supreme Court, and did (in my interpretation) only because second amendment questions were involved, questions stripped off by SCOTUS.  Freed on any Second Amendment implications, SCOTUS rightly slapped his argument down as stupid and said he was subject to the ban.  Seems sensible to me, and this sort of thing happens literally constantly in the courts -- the only oddball thing in my mind was how this incredibly arcane niche issue made it to the SCOTUS.

Instead, the article is breathless about describing this incredibly niche case as closing a "gaping loophole."  It is written as if it is some seminal event that overturns a horror just one-notch short of concentration camps  -- "This is a win for feminism, equality in the home, and in finally making movements on reigning in this country’s insane, libertarian approach to gun-owning."    And then of course the article bounces around in social media, making everyone who encounters it just a little bit dumber.

The Lifestyle Charity Fraud

For decades I have observed an abuse of charities that I am not sure has a name.  I call it the "lifestyle" charity or non-profit.  These are charities more known for the glittering fundraisers than their actual charitable works, and are often typified by having only a tiny percentage of their total budget flowing to projects that actually help anyone except their administrators.  These charities seem to be run primarily for the financial maintenance and public image enhancement of their leaders and administrators.  Most of their funds flow to the salaries, first-class travel, and lifestyle maintenance of their principals.

I know people first hand who live quite nicely as leaders of such charities -- having gone to two different Ivy League schools, it is almost impossible not to encounter such folks among our alumni.  They live quite well, and appear from time to time in media puff pieces that help polish their egos and reinforce their self-righteous virtue-signaling.  I have frequently attended my university alumni events where these folks are held out as exemplars for folks working on a higher plane than grubby business people like myself.  They drive me crazy.  They are an insult to the millions of Americans who do volunteer work every day, and wealthy donors who work hard to make sure their money is really making a difference.  My dad, who used his substantial business success to do meaningful things in the world virtually anonymously (like helping save a historically black college from financial oblivion), had great disdain for these people running lifestyle charities.

So I suppose the one good thing about the Clinton Foundation is it is raising some awareness about this kind of fraud.   This article portrays the RFK Human Rights charity as yet another example of this lifestyle charity fraud.

The Media's Role in Generating Polarization

A while back, I was asked to write a short essay answering the question of whether the National Parks should be privatized.  Here is my full answer.

Let me show you the first paragraph and a half of my answer, because I want to use it to make a point:

Should National Park’s be privatized, in the sense that they are turned entirely over to private owners?  No.  Public lands are in public hands for a reason — the public wants the government, not, say, Ritz-Carlton, to decide the use and character and access to the land.  No one wants a McDonald’s in front of Old Faithful, a common fear I hear time and again when privatization is mentioned.

However, once the agency determines the character of and facilities on the land, should their operation (as opposed to their ownership) be privatized?  Sure.   The NPS faces hundreds of millions of dollars in capital needs and deferred maintenance.  It is crazy to use its limited budget to have Federal civil service employees cleaning bathrooms and manning the gatehouse, when private companies have proven they can do a quality job so much less expensively....

It goes on from there, but I think that is a fairly nuanced and balanced answer, particularly given that I am probably the most vocal advocate in the country for public-private partnerships in public recreation.

But that nuance is not really interesting to the media.  They like point-counterpoint polarization.  So a web site called Blue Ridge Outdoors reprints me answer, but they edit it:


No one wants a McDonald’s in front of Old Faithful, a fear I hear time and again when privatization is mentioned. However, once the government determines how to manage a particular park, should its operation be privatized? Sure. The National Park Service faces hundreds of millions of dollars in capital needs and deferred maintenance. It is crazy to use that limited budget for federal employees to clean bathrooms and man the gatehouse, when private companies have proven they can do a quality job much less expensively.

So my answer, which is pretty much "no" gets edited to a "YES" and the entire first paragraph of nuance is deleted.    And we wonder why the world seems polarized?

The Middle Class Is Shrinking Because They Are Becoming Rich

I have made this point before, but Tyler Cowen has a great chart from a new study.  The explanation is here, but basically they have defined the bands based on some income break points corrected for family size and inflation over time.


A reader sent me a nice note with this link, saying that I had been right many years ago when I began making this point.  That's good, but I will also confess to be wrong on a related point -- I said 8 years ago that the one good thing about having a Democratic President was that the media would become much more positive suddenly about the economy.  On that, I was wrong.  The media still has a strong bias towards telling everyone that their life is getting ever worse, even when no such thing is true.

Citizens United Haters, Is This Really What You Want? John Oliver Brexit Segment Forced to Air After Vote

A lot of folks, particularly on the Left, despise the Citizens United decision that said it was unconstitutional to limit third party political speech, particularly prior to an election (even if that speech was made by nasty old corporations).  The case was specifically about whether the government could prevent the airing of a third-party produced and funded documentary about one of the candidates just before an election.  The Supreme Court said that the government could not put in place such limits (ie "Congress shall make no law...") but Britain has no such restrictions so we can see exactly what we would get in such a regime.  Is this what you want?

As Britain gears up to vote in the EU referendum later this week, broadcasters are constantly working to ensure their coverage remains impartial. One such company is Sky, which has this week been forced to delay the latest instalment of John Oliver's Last Week Tonight HBO show. Why? Because it contains a 15-minute diatribe on why the UK should remain part of Europe.

Instead of airing the programme after Game of Thrones on Sky Atlantic on Monday night, like it does usually, Sky has pushed it back until 10:10pm on Thursday, just after the polls close. Social media users are up in arms about the decision, but in reality, Sky appears to be playing everything by the book.

Sky's decision allows it to adhere to Ofcom rules that come into effect during elections and referendums. "Sky have complied with the Ofcom broadcasting restrictions at times of elections and referendums that prohibit us showing this section of the programme at this moment in time. We will be able to show it once the polls close have closed on Thursday," a Sky spokesperson told Engadget.

In March, the regulator warned broadcasters that they'd need to take care when covering May's local elections and the subsequent Brexit vote. Section Five (which focuses on Due Impartiality) and Section Six (covering Elections and Referendums) of Ofcom's Code contain guidelines that are designed stop companies like Sky from influencing the public vote. Satirical content is allowed on UK TV networks during these times, but Oliver's delivery is very much political opinion based on facts, rather than straight humour.

By the way, the fact vs. satire distinction strikes me as particularly bizarre and arbitrary.

When will folks realize that such speech limitations are crafted by politicians to cravenly protect themselves from criticism.  Take that Citizens United decision.  Hillary Clinton has perhaps been most vociferous in her opposition to it, saying that if President she will appoint Supreme Court judges that will overturn it.  But note the specific Citizens United case was about whether a documentary critical of .... Hillary Clinton could be aired.  So Clinton is campaigning that when she takes power, she will change the Constitution so that she personally cannot be criticized.  And the sheeple on the Left nod and cheer as if shielding politicians from accountability is somehow "progressive."


Denying the Climate Catastrophe: 5a. Arguments For Attributing Past Warming to Man

This is part A of Chapter 5 of an ongoing series.  Other parts of the series are here:

  1. Introduction
  2. Greenhouse Gas Theory
  3. Feedbacks
  4.  A)  Actual Temperature Data;  B) Problems with the Surface Temperature Record
  5. Attribution of Past Warming:  A) Arguments for it being Man-Made (this article); B) Natural Attribution
  6. Climate Models vs. Actual Temperatures
  7. Are We Already Seeing Climate Change
  8. The Lukewarmer Middle Ground
  9. A Low-Cost Insurance Policy

Having established that the Earth has warmed over the past century or so (though with some dispute over how much), we turn to the more interesting -- and certainly more difficult -- question of finding causes for past warming.  Specifically, for the global warming debate, we would like to know how much of the warming was due to natural variations and how much was man-made.   Obviously this is hard to do, because no one has two thermometers that show the temperature with and without man's influence.

I like to begin each chapter with the IPCC's official position, but this is a bit hard in this case because they use a lot of soft words rather than exact numbers.  They don't say 0.5 of the 0.8C is due to man, or anything so specific.   They use phrases like "much of the warming" to describe man's affect.  However, it is safe to say that most advocates of catastrophic man-made global warming theory will claim that most or all of the last century's warming is due to man, and that is how we have put it in our framework below:

click to enlarge

By the way, the "and more" is not a typo -- there are a number of folks who will argue that the world would have actually cooled without manmade CO2 and thus manmade CO2 has contributed more than the total measured warming.  This actually turns out to be an important argument, since the totality of past warming is not enough to be consistent with high sensitivity, high feedback warming forecasts.  But we will return to this in part C of this chapter.

Past, Mostly Abandoned Arguments for Attribution to Man

There have been and still are many different approaches to the attributions problem.  In a moment, we will discuss the current preferred approach.  However, it is worth reviewing two other approaches that have mostly been abandoned but which had a lot of currency in the media for some time, in part because both were in Al Gore's film An Inconvenient Truth.

Before we get into them, I want to take a step back and briefly discuss what is called paleo-climatology, which is essentially the study of past climate before the time when we had measurement instruments and systematic record-keeping for weather.   Because we don't have direct measurements, say, of the temperature in the year 1352, scientists must look for some alternate measure, called a "proxy,"  that might be correlated with a certain climate variable and thus useful in estimating past climate metrics.   For example, one might look at the width of tree rings, and hypothesize that varying widths in different years might correlate to temperature or precipitation in those years.  Most proxies take advantage of such annual layering, as we have in tree rings.

One such methodology uses ice cores.  Ice in certain places like Antarctica and Greenland is laid down in annual layers.  By taking a core sample, characteristics of the ice can be measured at different layers and matched to approximate years.  CO2 concentrations can actually be measured in air bubbles in the ice, and atmospheric temperatures at the time the ice was laid down can be estimated from certain oxygen isotope ratios in the ice.  The result is that one can plot a chart going back hundreds of thousands of years that estimates atmospheric CO2 and temperature.  Al Gore showed this chart in his movie, in a really cool presentation where the chart wrapped around three screens:

click to enlarge

As Gore points out, this looks to be a smoking gun for attribution of temperature changes to CO2.  From this chart, temperature and CO2 concentrations appear to be moving in lockstep.  From this, CO2 doesn't seem to be a driver of temperatures, it seems to be THE driver, which is why Gore often called it the global thermostat.

But there turned out to be a problem, which is why this analysis no longer is treated as a smoking gun, at least for the attribution issue.  Over time, scientists got better at taking finer and finer cuts of the ice cores, and what they found is that when they looked on a tighter scale, the temperature was rising (in the black spikes of the chart) on average 800 years before the CO2 levels (in red) rose.

This obviously throws a monkey wrench in the causality argument.  Rising CO2 can hardly be the cause of rising temperatures if the CO2 levels are rising after temperatures.

It is now mostly thought that what this chart represents is the liberation of dissolved CO2 from oceans as temperatures rise.  Oceans have a lot of dissolved CO2, and as the oceans get hotter, they will give up some of this CO2 to the atmosphere.

The second outdated attribution analysis we will discuss is perhaps the most famous:  The Hockey Stick.  Based on a research paper by Michael Mann when he was still a grad student, it was made famous in Al Gore's movie as well as numerous other press articles.  It became the poster child, for a few years, of the global warming movement.

So what is it?  Like the ice core chart, it is a proxy analysis attempting to reconstruct temperature history, in this case over the last 1000 years or so.  Mann originally used tree rings, though in later versions he has added other proxies, such as from organic matter laid down in sediment layers.

Before the Mann hockey stick, scientists (and the IPCC) believed the temperature history of the last 1000 years looked something like this:

click to enlarge

Generally accepted history had a warm period from about 1100-1300 called the Medieval Warm Period which was warmer than it is today, with a cold period in the 17th and 18th centuries called the "Little Ice Age".  Temperature increases since the little ice age could in part be thought of as a recovery from this colder period.  Strong anecdotal evidence existed from European sources supporting the existence of both the Medieval Warm Period and the Little Ice Age.  For example, I have taken several history courses on the high Middle Ages and every single professor has described the warm period from 1100-1300 as creating a demographic boom which defined the era (yes, warmth was a good thing back then).  In fact, many will point to the famines in the early 14th century that resulted from the end of this warm period as having weakened the population and set the stage for the Black Death.

However, this sort of natural variation before the age where man burned substantial amounts of fossil fuels created something of a problem for catastrophic man-made global warming theory.  How does one convince the population of catastrophe if current warming is within the limits of natural variation?  Doesn't this push the default attribution of warming towards natural factors and away from man?

The answer came from Michael Mann (now Dr. Mann but actually produced originally before he finished grad school).  It has been dubbed the hockey stick for its shape:


click to enlarge

The reconstructed temperatures are shown in blue, and gone are the Medieval Warm Period and the Little Ice Age, which Mann argued were local to Europe and not global phenomena.  The story that emerged from this chart is that before industrialization, global temperatures were virtually flat, oscillating within a very narrow band of a few tenths of a degree.  However, since 1900, something entirely new seems to be happening, breaking the historical pattern.  From this chart, it looks like modern man has perhaps changed the climate.  This shape, with the long flat historical trend and the sharp uptick at the end, is why it gets the name "hockey stick."

Oceans of ink and electrons have been spilled over the last 10+ years around the hockey stick, including a myriad of published books.  In general, except for a few hard core paleoclimatologists and perhaps Dr. Mann himself, most folks have moved on from the hockey stick as a useful argument in the attribution debate.  After all, even if the chart is correct, it provides only indirect evidence of the effect of man-made CO2.

Here are a few of the critiques:

  • Note that the real visual impact of the hockey stick comes from the orange data on the far right -- the blue data alone doesn't form much of a hockey stick.  But the orange data is from an entirely different source, in fact an entirely different measurement technology -- the blue data is from tree rings, and the orange is form thermometers.  Dr. Mann bristles at the accusation that he "grafted" one data set onto the other, but by drawing the chart this way, that is exactly what he did, at least visually.  Why does this matter?  Well, we have to be very careful with inflections in data that occur exactly at the point that where we change measurement technologies -- we are left with the suspicion that the change in slope is due to differences in the measurement technology, rather than in the underlying phenomenon being measured.
  • In fact, well after this chart was published, we discovered that Mann and other like Keith Briffa actually truncated the tree ring temperature reconstructions (the blue line) early.  Note that the blue data ends around 1950.  Why?  Well, it turns out that many tree ring reconstructions showed temperatures declining after 1950.  Does this mean that thermometers were wrong?  No, but it does provide good evidence that the trees are not accurately following current temperature increases, and so probably did not accurately portray temperatures in the past.
  • If one looks at the graphs of all of Mann's individual proxy series that are averaged into this chart, astonishingly few actually look like hockey sticks.  So how do they average into one?  McIntyre and McKitrick in 2005 showed that Mann used some highly unusual and unprecedented-to-all-but-himself statistical methods that could create hockey sticks out of thin air.  The duo fed random data into Mann's algorithm and got hockey sticks.
  • At the end of the day, most of the hockey stick (again due to Mann's averaging methods) was due to samples from just a handful of bristle-cone pine trees in one spot in California, trees whose growth is likely driven by a number of non-temperature factors like precipitation levels and atmospheric CO2 fertilization.   Without these few trees, most of the hockey stick disappears.  In later years he added in non-tree-ring series, but the results still often relied on just a few series, including the Tiljander sediments where Mann essentially flipped the data upside down to get the results he wanted.  Taking out the bristlecone pines and the abused Tiljander series made the hockey stick go away again.

There have been plenty of other efforts at proxy series that continue to show the Medieval Warm Period and Little Ice Age as we know them from the historical record


click to enlarge

As an aside, Mann's hockey stick was always problematic for supporters of catastrophic man-made global warming theory for another reason.  The hockey stick implies that the world's temperatures are, in absence of man, almost dead-flat stable.   But this is hardly consistent with the basic hypothesis, discussed earlier, that the climate is dominated by strong positive feedbacks that take small temperature variations and multiply them many times.   If Mann's hockey stick is correct, it could also be taken as evidence against high climate sensitivities that are demanded by the catastrophe theory.


The Current Lead Argument for Attribution of Past Warming to Man

So we are still left wondering, how do climate scientists attribute past warming to man?  Well, to begin, in doing so they tend to focus on the period after 1940, when large-scale fossil fuel combustion really began in earnest.   Temperatures have risen since 1940, but in fact nearly all of this rise occurred in the 20 year period from 1978 to 1998:


click to enlarge

To be fair, and better understand the thinking at the time, let's put ourselves in the shoes of scientists around the turn of the century and throw out what we know happened after that date.  Scientists then would have been looking at this picture:

click to enlarge

Sitting in the year 2000, the recent warming rate might have looked dire .. nearly 2C per century...

click to enlarge

Or possibly worse if we were on an accelerating course...

click to enlarge

Scientists began to develop a hypothesis that this temperature rise was occurring too rapidly to be natural, that it had to be at least partially man-made.  I have always thought this a slightly odd conclusion, since the slope from this 20-year period looks almost identical to the slope centered around the 1930's, which was very unlikely to have much human influence.

But never-the-less, the hypothesis that the 1978-1998 temperature rise was too fast to be natural gained great currency.  But how does one prove it?

What scientists did was to build computer models to simulate the climate.  They then ran the computer models twice.  The first time they ran them with only natural factors, or at least only the natural factors they knew about or were able to model (they left a lot out, but we will get to that in time).  These models were not able to produce the 1978-1998 warming rates.  Then, they re-ran the models with manmade CO2, and particularly with a high climate sensitivity to CO2 based on the high feedback assumptions we discussed in an earlier chapter.   With these models, they were able to recreate the 1978-1998 temperature rise.   As Dr. Richard Lindzen of MIT described the process:

What was done, was to take a large number of models that could not reasonably simulate known patterns of natural behavior (such as ENSO, the Pacific Decadal Oscillation, the Atlantic Multidecadal Oscillation), claim that such models nonetheless accurately depicted natural internal climate variability, and use the fact that these models could not replicate the warming episode from the mid seventies through the mid nineties, to argue that forcing was necessary and that the forcing must have been due to man.

Another way to put this argument is "we can't think of anything natural that could be causing this warming, so by default it must be man-made.  With various increases in sophistication, this remains the lead argument in favor of attribution of past warming to man.

In part B of this chapter, we will discuss what natural factors were left out of these models, and I will take my own shot at a simple attribution analysis.

The next section, Chapter 6 Part B, on natural attribution is here

Denying the Climate Catastrophe: 4a. Actual Temperature Data

This is the fourth chapter of an ongoing series.  Other parts of the series are here:

  1. Introduction
  2. Greenhouse Gas Theory
  3. Feedbacks
  4.  A)  Actual Temperature Data (this article);   B) Problems with the Surface Temperature Record
  5. Attribution of Past Warming:  A) Arguments for it being Man-Made; B) Natural Attribution
  6. Climate Models vs. Actual Temperatures
  7. Are We Already Seeing Climate Change
  8. The Lukewarmer Middle Ground
  9. A Low-Cost Insurance Policy

In our last chapter, we ended a discussion on theoretical future warming rates by saying that no amount of computer modelling was going to help us choose between various temperature sensitivities and thus warming rates.  Only observational data was going to help us determine how the Earth actually responds to increasing CO2 in the atmosphere.  So in this chapter we turn to the next part of our framework, which is our observations of Earth's temperatures, which is among the data we might use to support or falsify the theory of catastrophic man-made global warming.

The IPCC position is that the world (since the late 19th century) has warmed about 0.8C.  This is a point on which many skeptics will disagree, though perhaps not as substantially as one might expect from the media.   Most skeptics, myself included, would agree that the world has certainly warmed over the last 100-150 years.  The disagreement tends to be in the exact amount of warming, with many skeptics contending that the amount of warming has been overstated due to problems with temperature measurement and aggregation methodology.

For now, we will leave those issues aside until part B of this section, where we will discuss some of these issues.  One reason to do so is to focus, at least at first, on the basic point of agreement that the Earth has indeed warmed somewhat.  But another reason to put these differences over magnitude aside is that we will find, a few chapters hence, that they essentially don't matter.  Even the IPCC's 0.8C estimate of past warming does not support its own estimates of temperature sensitivity to CO2.

Surface Temperature Record

The most obvious way to measure temperatures on the Earth is with thermometers near the ground.   We have been measuring the temperature at a few select locations for hundreds of years, but it really is only in the last century that we have fairly good coverage of the land surface.  And even then our coverage of places like the Antarctic, central Africa, parts of South America, and all of the oceans (which cover 75% of the Earth) is even today still spotty.  So coming up with some sort of average temperature for the Earth is not a straight averaging exercise -- data must be infilled and estimated, making the process complicated and subject to a variety of errors.

But the problem is more difficult than just data gaps.  How does one actually average a temperature from Denver with a temperature from San Diego?  While a few folks attempt such a straight average, scientists have developed a theory that one can more easily average what are known as temperature anomalies than one can average the temperature itself.  What is an anomaly?  Essentially, for a given thermometer, researchers will establish an average for that thermometer for a particular day of the year.  The exact time period or even the accuracy of this average is not that important, as long as the same time period is used consistently.  Then, the anomaly for any given measurement is the deviation of the measured temperature from its average.   So if the average historical temperature for this day of the year is 25C and the actual measured for the day is 26C, the anomaly for today at this temperature station is +1.0C.

Scientists then develop programs that spatially average these temperature anomalies for the whole Earth, while also adjusting for a myriad of factors, from time-of-day changes in measurement to technology changes over time of the temperature stations to actual changes in the physical location of the measurement.  This is a complicated enough a task, with enough explicit choices that must be made about techniques and adjustments, that there are many different temperature metrics floating around out there, many of which get different results from essentially the same data.  The Hadley Center in England's CRUT4 global temperature metric is generally considered the gold standard, and is the one used preferentially by the IPCC.  Its metric is shown below, with the monthly temperature anomaly in dark blue and the 5 year moving average (centered on its mid-point):

Again, the zero point of the chart is arbitrary and merely depends on the period of time chosen as the base or average.  Looking at the moving average, one can see the temperature anomaly bounces around -0.3C in the late 19th century and has been around +0.5C over the last several years, which is how we get to about 0.8C warming.

Satellite Temperature Record

There are other ways to take temperature measurements, however.  Another approach is to use satellites to measure surface temperatures (or at least near-surface temperatures).   Satellites measure temperature by measuring the thermal microwave emissions of oxygen atoms in the lower troposphere (perhaps 0-3 miles above the Earth).  Satellites have the advantage of being able to look at the entire Earth without gaps, and are not subject to siting biases for surface temperatures stations (which will be discussed in our part B of this chapter).

The satellite record does, however, rely on a shifting array of satellites all of which have changing orbits for which adjustments must be made.  Of necessity, the satellite record cannot reach as far back into the past.  And the satellites are not actually measuring the temperature of the Earth, but rather a temperature a mile or two up.  Whether that matters is subject to debate, but the clincher for me is that the IPCC and most climate models have always shown that the first and most anthropogenic warming should show up in exactly this spot -- the lower troposphere -- which makes observation of this zone a particularly good way to look for a global warming signal.

Roy Spencer and John Christy have what is probably the leading satellite temperature metric, called "UAH" as a shorthand for University of Alabama, Huntsville's space science center.  The UAH record looks like this:

Note that the absolute magnitude of the anomaly isn't comparable between the surface and satellite record, as they use different base periods, but changes and growth rates in the anomalies should be comparable between the two indices.

The first thing to note is that, though they are different, both the satellite and surface temperature records show warming since 1980.  For all that some skeptics may want to criticize the authors of the surface temperature databases, and there indeed some grounds for criticism, these issues should not distract us from the basic fact that in every temperature record we have (including other technologies like radiosonde balloons), we see recent warming.

In terms of magnitude, the two indices do not show the same amount of warming -- since 1980 the satellite temperature record shows about 30% less warming than does  the surface temperature record for the same period.   So which is right?  We will discuss this in more depth in part B, but the question is not made any easier by the fact that the surface records are compiled by prominent alarmist scientists while the satellite records are maintained by prominent skeptic scientists.  Which causes each side to accuse the other of having its thumb on the scale, so to speak.  I personally like the satellite record because of its larger coverage areas and the fact that its manual adjustments (which are required of both technologies) are for a handful of instruments rather than thousands, and are thus easier to manage and get right.  But I am also increasingly of the opinion that the differences are minor, and that neither are consistent with catastrophic forecasts.

So instead of getting ourselves involved in the dueling temperature data set food fight (we will dip our toe into this in part B), let's instead apply both these data sets to several propositions we see frequently in the media.  We will quickly see the answers we reach do not depend on the data set chosen.

Test #1:  Is Global Warming Accelerating

One frequent meme you will hear all the time is that "global warming is accelerating."  As of today it had 550,000 results on Google.  For example:

So.  Is that true?  They can't print it if its not true, right (lol)?  Let's look first at the satellite record through the end of 2015 when this presentation was put together (there is an El Nino driven spike in 2 months after this chart was made, which does not affect the conclusions that follow in the least, but I will update to include ASAP).

If you want a name for this chart, I could call it the "bowl of cherries" because it has become a cherry-picker's delight.   Everyone in the debate can find a starting point and an end point in this jagged data to find any trend they want to find.  So how do we find an objective basis to define end points for this analysis?  Well, my background is more in economic analysis.  Economists have the same problem in looking at trends for things like employment or productivity because there is a business cycle that adds volatility to these numbers above and beyond any long term trend.  One way they manage this is to measure variables from peak to peak of the economic cycle.

I have done something similar.  The equivalent cyclical peaks in the temperature world are probably the very high Pacific Decadal Oscillation, or El Nino, events.  There was one in 1998 and there is one occurring right now in late 2015/early 2016.  So I defined my period as 18 years from peak to peak.  By this timing, the satellite record shows temperatures to be virtually dead flat for those 18 years.  This is "the pause" that you may have heard of in climate debates.   Such an extended pause is not predicted by global warming theory, particularly when the theory (as in the IPCC main case) assumes high temperature sensitivities to CO2 and low natural variation in temperatures.

So if global warming were indeed accelerating, we would expect the warming rate over the last 18 years to be higher than the rate over the previous 18 years.  But just the opposite is true:

While "the pause" does not in and of itself disprove the theory of catastrophic manmade global warming, it does easily falsify the myriad statements you see that global warming is accelerating.  At least for the last 20 years, it has been decelerating.

By the way, this is not somehow an artifact of just the satellite record.  This is what the surface record looks like for the same periods:

Though it shows (as we discussed earlier) higher overall warming rates, the surface temperature record also shows a deceleration rather than acceleration over the last 20 years.


Test #2:  Are Temperatures Rising Faster than Expected

OK, let's consider another common meme, that the "earth is warming faster than predicted."

click to enlarge

Again, there over 500,000 Google matches for this meme.  So how do we test it?  Well, certainly not against the last IPCC forecasts -- they are only a few years old.  The first real high-sensitivity or catastrophic forecast we have is from James Hansen, often called the father of global warming.

click to enlarge

In June of 1988, Hanson made a seminal presentation to Congress on global warming, including this very chart (sorry for the sucky 1980's graphics).  In his testimony, he presented his models for the Earth's temperature, which showed a good fit with history**.  Using his model, he then created three forecasts:  Scenario A, with high rates of CO2 emissions;  Scenario B, with more modest emissions; and scenario C, with drastic worldwide emissions cuts (plus volcanoes, that tend to belch dust and chemicals that have a cooling effect).  Surprisingly, we can't even get agreement today about which forecast for CO2 production was closer to the mark (throwing in the volcanoes makes things hard to parse) but it is pretty clear that over the 30 years after this forecast, the Earth's CO2 output has been somewhere between A and B.

As it turns out, it doesn't matter whether we actually followed the CO2 emissions from A or B.  The warming forecasts for scenario A and B turn out to be remarkably similar.  In the past, I used to just overlay temperature actuals onto Hansen's chart, but it is a little hard to get the zero point right and it led to too many food fights.  So let's pull the scenario A and B forecasts off the chart and compare them a different way.

click to enlarge

The left of chart shows Hanson's scenario A and B, scanned right from his chart.  Scenario A implies a warming rate from 1986 to 2016 of 3.1C per century.  Scenario B is almost as high, at 2.8C per century.  But as you can see on the right, the actual warming rates we have seen over the same period are well below these forecasts.  The surface temperature record shows only about half the warming, and the satellite record shows only about a third the warming, that Hansen predicted.   There is no justification for saying that recent warming rates have been higher than expected or forecast -- in fact, the exact opposite has been true.

We see the same thing when looking at past IPCC forecasts.  At each of its every-five-year assessments, the IPCC has included a forecast range for future temperatures.  In this case, though, we don't have to create a comparison with actuals because the most recent (5th) IPCC Assessment did it for us:

The colored bands are their past forecasts.  The grey areas are the error bands on the forecast.  The black dots are global temperatures (which actually are shown with error bars, which is good practice but seldom done except perhaps when they are trying to stretch to get into the forecast range).  As you can see, temperatures have been so far below forecasts that they are dropping out of the low end of even the most generous forecast bands.  If temperatures were rising faster than expected, the black dots would be above the orange and yellow bands.  We therefore have to come to the conclusion that, at least for the last 20-30 years, temperatures have not been rising faster than expected, they have been rising slower than expected.

Day vs. Night

There is one other phenomenon we can see in the temperature data that we will come back to in later chapters:  that much of the warming over the last century has been at night, rather than in the daytime.   There are two possible explanations for this.  The first is that most anthropogenic warming models predict more night time warming than they do day time warming.  The other possibility is that a portion of the warming in the 20th century temperature record is actually spurious bias from the urban heat island effect due to siting of temperature stations near cities, since urban heat island warming shows up mainly at night.  We will discuss the latter effect in part B of this chapter.

Whatever the cause, much of the warming we have seen has occurred at night, rather than during the day.  Here is a great example from the Amherst, MA temperature station (Amherst was the first location where I gave this presentation, if that seems an odd choice).

Click to enlarge

As you can see, the warming rate since 1945 is 5 times higher at night than during the day.  This directly affects average temperatures since daily average temperature for a location in the historic record is the simple average of the daily high and daily low.  Yes, I know that this is not exactly accurate, but given technology in the past, this is the best that could be done.

The news media likes to cite examples of heat waves and high temperature records as a "proof" of global warming.   We will discuss this later, but this is obviously a logical fallacy -- one can't prove a trend in noisy data simply by citing isolated data points in one tail of the distribution.  But it is also fallacious for another reason -- we are not actually seeing any upwards trends in high temperature records, at least for daytime highs:

Click to enlarge

To get this chart, we obviously have to eliminate newer temperature stations from the data set -- any temperature station that is only 20 years old will have all of its all time records in the last 20 years (you would be surprised at how many otherwise reputable scientists miss simple things like this).  Looking at just the temperature stations in the US we have a long record for, we see with the black line that there is really no upwards trend in the number of high temperature records (Tmax) being set.   The 1930s were brutally hot, and if not for some manual adjustments we will discuss in part B of this section, they would likely still show as the hottest recent era for the US.   It turns out, with the grey line (Tmin), that while there is still no upward trend, we are actually seeing more high temperature records being set with daily lows (the highest low, as it were) than we are with daily highs.  The media is, essentially, looking in the wrong place, but I sympathize because a) broiling hot daytime highs are sexier and b) it is brutally hard to talk about highest low temperatures without being confusing as hell.

In our next chapter, or really part B of this chapter, we will discuss some of the issues that may be leading the surface temperature record to be exaggerated, or at least inaccurate.

Chapter 4, Part B on problems with the surface temperature record continues here.

If you want to skip Part B, and get right on with the main line of the argument, you can go straight to Chapter 5, part A, which starts in on the question of how much of past warming can be attributed to man.


** Footnote:  The history of Wall Street is full of bankrupt people whose models exactly matched history.  I have done financial and economic modeling for decades, and it is surprisingly easy to force multi-variable models to match history.  The real test is how well the model works going forward.  Both Hanson's 1988 models and the IPCC's many models do an awesome job matching history, but quickly go off the rails in future years.  I am reminded of a simple but famous example of the perfect past correlation between certain NFL outcomes and Presidential election outcomes.   This NFL model of presidential elections perfectly matches history, but one would be utterly mad to bet future elections based on it.
