Coyote on the Real Clear Radio Hour

Bill Frezza interviewed me for his show the other day.  I felt it was not one of my better performances but he says he is a wizard of editing so we will see.  Anyway, I am actually sharing the show with Coyote-favorite Dr. Richard Lindzen, so at least that half of the show should be worth your time.  Here are the details:

Tune in Saturday, February 13th to RealClear Radio Hour with Bill Frezza with guests Richard Lindzen and Warren Meyer.

You can listen live on Bloomberg’s Boston iHeartRadio or Bloomberg’s San Francisco iHeartRadioSaturdays at 10a PT/ 1p ET, 4p PT/ 7p ET or Sundays at 1a PT/ 4a ET.

Government Science Monopoly

Richard Lindzen, atmospheric physicist, MIT professor emeritus, and lead author of the “Physical Climate Processes and Feedbacks” chapter of the 2001 Intergovernmental Panel on Climate Change report, attributes climate hype to politics, money, and propaganda. Lindzen particularly takes issue with the “97% consensus” claim that is being used to stifle debate and demonize skeptics.

Rescuing Public Parks

Warren Meyer, founder and president of Recreation Resource Management, shares how he has successfully managed public parks for nearly 25 years. Meyer advocates for whole park concessions—privatized management of public parks—to save them from closure and agency mismanagement.

We Are All Lukewarmers Now

Matt Ridley has another very good editorial in the WSJ that again does a great job of outlining what I think of as the core skeptic position.  Read the whole thing, but a few excerpts:

The United Nations' Intergovernmental Panel on Climate Change will shortly publish the second part of its latest report, on the likely impact of climate change. Government representatives are meeting with scientists in Japan to sex up—sorry, rewrite—a summary of the scientists' accounts of storms, droughts and diseases to come. But the actual report, known as AR5-WGII, is less frightening than its predecessor seven years ago.

The 2007 report was riddled with errors about Himalayan glaciers, the Amazon rain forest, African agriculture, water shortages and other matters, all of which erred in the direction of alarm. This led to a critical appraisal of the report-writing process from a council of national science academies, some of whose recommendations were simply ignored.

Others, however, hit home. According to leaks, this time the full report is much more cautious and vague about worsening cyclones, changes in rainfall, climate-change refugees, and the overall cost of global warming.

It puts the overall cost at less than 2% of GDP for a 2.5 degrees Centigrade (or 4.5 degrees Fahrenheit) temperature increase during this century. This is vastly less than the much heralded prediction of Lord Stern, who said climate change would cost 5%-20% of world GDP in his influential 2006 report for the British government.

It is certainly a strange branch of science where major reports omit a conclusion because that conclusion is not what they wanted to see

The IPCC's September 2013 report abandoned any attempt to estimate the most likely "sensitivity" of the climate to a doubling of atmospheric carbon dioxide. The explanation, buried in a technical summary not published until January, is that "estimates derived from observed climate change tend to best fit the observed surface and ocean warming for [sensitivity] values in the lower part of the likely range." Translation: The data suggest we probably face less warming than the models indicate, but we would rather not say so.

Readers of this site will recognize this statement

None of this contradicts basic physics. Doubling carbon dioxide cannot on its own generate more than about 1.1C (2F) of warming, however long it takes. All the putative warming above that level would come from amplifying factors, chiefly related to water vapor and clouds. The net effect of these factors is the subject of contentious debate.

I have reluctantly accepted the lukewarmer title, though I think it is a bit lame.

In climate science, the real debate has never been between "deniers" and the rest, but between "lukewarmers," who think man-made climate change is real but fairly harmless, and those who think the future is alarming. Scientists like Judith Curry of the Georgia Institute of Technology and Richard Lindzen of MIT have moved steadily toward lukewarm views in recent years.

When I make presentations, I like to start with the following (because it gets everyone's attention):  "Yes, I am a denier.  But to say 'denier', implies that one is denying some specific proposition.  What is that proposition?  It can't be 'global warming' because propositions need verbs, otherwise it is like saying one denies weather.  I don't deny that the world has warmed over the last century.  I don't deny that natural factors play a role in this (though many alarmists seem to).  I don't even deny that man has contributed incrementally to this warming.  What I deny is the catastrophe.  Specifically, I deny that man's CO2 will warm the Earth enough to create a catastrophe.  I define "catastrophe" as an outcome where the costs of immediately reducing CO2 output with the associated loss in economic growth would be substantially less than the cost of future adaption and abatement. "

It is Important to Call Foul on One's Allies as Well, and This From Christopher Monkton is Bad Stuff

Christopher Monkton has been a very public supporter of the climate skeptic position.  I think he sometimes gets his science wrong, but he is glib and entertaining and by his position as peer of the realm he gets media space not available to many of us.

But this is bad, bad, bad.  He is calling for using British libel law against an alarmist who merely disagrees.  I have not problem with most of his factual defenses of Richard Lindzen.  But the points he labels "lies" are more accurately described as areas where people disagree on data source and interpretation.  Turning this into libel, under the egregiously onerous British libel laws, is a terrible precedent.

The climate debate is already over-full with vilification and ad hominem attacks.  The last thing we need is to throw British courts into the equation.

Lindzen on Global Warming

Richard Lindzen has a great article out that summarizes much of the skeptic's case.  I do not have time to excerpt it right now, but I don't have to because Bruce McQuain does such good job.  If you find Lindzen's arguments interesting, I encourage you to watch my climate video that makes many of the same points with the addition of graphics and charts to make the points clearer to those who don't spend all their time wallowing around in these climate issues.

The Crux of the Climate Debate

Cross-posted from Climate Skeptic

I wanted to link to Richard Lindzen's Congressional testimony.  For slides, they are pretty easy to follow as they are mostly text.  I want to particularly point out slide 4, which I think on one page outlines the single most important point to understand about anthropogenic global warming theory.  When given just one minute to discuss climate, this slide embodies the message I give.

Here are two statements that are completely agreed on by the IPCC. It is crucial to be aware of their implications.

1. A doubling of CO2, by itself, contributes only about 1C to greenhouse warming. All models project more warming, because, within models, there are positive feedbacks from water vapor and clouds, and these feedbacks are considered by the IPCC to be uncertain.

2. If one assumes all warming over the past century is due to anthropogenic greenhouse forcing, then the derived sensitivity of the climate to a doubling of CO2is less than 1C. The higher sensitivity of existing models is made consistent with observed warming by invoking unknown additional negative forcings from aerosols and solar variability as arbitrary adjustments.

Given the above, the notion that alarming warming is "˜settled science' should be offensive to any sentient individual, though to be sure, the above is hardly emphasized by the IPCC. 4

My most recent climate video, which discusses this issue and more, is here.  I also have an older, shorter video focusing on just the issues in Lindzen's fourth slide here.
