One of the fathers of Germany’s modern green movement, Professor Dr. Fritz Vahrenholt, a social democrat and green activist, decided to author a climate science skeptical book together with geologist/paleontologist Dr. Sebastian Lüning. Vahrenholt’s skepticism started when he was asked to review an IPCC report on renewable energy. He found hundreds of errors. When he pointed them out, IPCC officials simply brushed them aside. Stunned, he asked himself, “Is this the way they approached the climate assessment reports?”

I have not seen the book nor the Der Spiegel feature, but I can say that, contrary to the various memes running around, many science-based skeptics became such by exactly this process — looking at the so-called settled science and realizing a lot of it was really garbage.  Not because we were paid off in oil money or mesmerized by Rush Limbaugh, but because the actual detail behind many of the IPCC conclusions is really a joke.

For tomorrow, I am working on an article I have been trying to write literally for years.  One of the confusing parts of the climate debate is that there are really portions of the science that are pretty solid.  When skeptics point to other parts of the science that is not well-done, defenders tend to run back to the solid parts and point to those.  That is why Michael Mann frequently answers his critics by saying that skeptics are dumb because they don’t accept greenhouse gas theory, but most skeptics do indeed accept greenhouse gas theory, what they don’t accept is the separate theory that the climate is dominated by positive feedbacks that amplify small warming from CO2 into a catastrophe.

This is an enormous source of confusion in the debate, facilitated by a scientifically illiterate press and alarmists who explicitly attempt to make this bate and switch so they can avoid arguing the tough points.  Even the author linked above is confused on this

Skeptic readers should not think that the book will fortify their existing skepticism of CO2 causing warming. The authors agree it does. but have major qualms about the assumed positive CO2-related feed-backs and believe the sun plays a far greater role in the whole scheme of things.

This is in fact exactly the same position that most skeptics, at least the science-based non-talkshow-host ones have.  Look for my Forbes piece tomorrow.

Certainly it strikes most folks as unethical to lose the assets in your customers’ brokerage accounts making bets for the house.  But it turns out, it may have been entirely legal.  This article is quite good, and helps explain what was going on, what this “hypothecation” thing is (basically a fancy term for leveraging up assets by using them as collateral on loans), and why it may have been legal.

In short, the article discusses two regulatory changes that seemed to be important.  The first was a 2000 (ie Clinton era, for those who still think these regulatory screwups are attributable to a single Party) relaxation in how brokerages could invest customers’ collateral in their trading accounts.  The second was a loophole where brokerages created subsidiaries in countries with no controls on how client money was re-used (in this case mostly the UK) and used those subsidiaries to reinvest money even in US brokerage accounts.

The increase in leverage was staggering.  Already, cash in most commodities trading accounts is leveraged – customers might have only 30% of the value of their trading positions as collateral on their margin account.  Then the brokerage houses took this collateral and used it as collateral on new loans.  Those receiving the collateral on the other end often did the same.

MF Global would be bad if it were fraud.  But it is even worse if MF Global is doing legally what every other brokerage house is still doing.

Here is the minimum one should do:  Diversify brokerage accounts.  We diversify between bonds and stocks and other investments, but many people have everything in one account with one company.  I am not sure anyone can be trusted any more.  My mutual funds are now spread across three firms and, if I grow my brokerage account for individual stocks and investments (right now it is tiny) I will split that as well.

At first I thought this was about an end to self-segregation of the middle class.  After all, if middle class neighborhoods are gone, but middle class people are still living somewhere, then they must be living mixed up with other groups.

But then Drum says the problem is the increasing self-segregation of the middle class.  Huh?  How can they be self-segregating more but we end up with fewer all middle class neighborhoods?

But then the problem appears to be that the middle class want to hang out with the rich people.    Um, OK, I don’t find this wildly surprising, though the evidence he cites for this is awful, the typical low standard of science practiced by sociologists everywhere.  But Drum himself admits he self-segregates with more educated people, so there you have your proof.

Finally, as usually is the case with the Left, the problem turns out to be not with the middle class at all but with rich people

We’ve been fretting for a long time about the rise of gated communities, the abandonment of public schools by prosperous city residents, and the booming market in McMansions. And more and more, this kind of segregation doesn’t apply only to the truly rich. Increasingly, even the merely well off hardly have any social interaction outside their own class: they live in different neighborhoods, eat in different restaurants, send their kids to different schools and different sports leagues, and vacation in different places.

Really?  Like you had a much better chance as a poor person to be hanging out with Andrew Carnegie at the pub than you do today chilling with Bill Gates at a Starbucks?  When was this magic past time when the affluent liked to mix more with the unwashed?  I hate to just use my personal observations, but Drum does, so here is mine:  I feel like many of our meeting places today are less rather than more exclusive.  I know a lot of very rich folks, and they simply don’t cloister themselves in exclusive clubs and stores like they used to — I am not at all surprised to see them in the Costco or at the public golf course.

I can be persuaded to accept schools as an exception to this, but this hardly does much to help Drum’s argument as the government school system has been run (and run into the ground) by his fellow progressives for decades.  It says a lot about private vs. public solutions that Costco has found a way to appeal equally to rich and poor but the public schools have not.

Update:  From the NYT article on the underlying study, note the problem on these maps- the urban boundary in the study is static, so as the city expands, more of the metro area is outside the bounds of the study area.  What group likely is the predominent occupant of new suburbs on the leading edge of urban boundaries?  Dare I say middle class?

The central core of older American cities has always been where the richest and poorest live.You can see this on the Philadelphia maps.  The pattern is not changing, just each area is getting larger.  A full picture would show the middle class area expanding out as well, but the study cuts off the boundary at arbitrary country lines and never expands the boundary as the city’s geographic size grows.  The “trend” they are supposedly seeing are middle class continuing to move outwards from the city center, and their flawed study methodology  loses visibility to them.  This makes more sense than the study’s finding, that somehow there is this weird lake Wobegon-type effect where no one is in the middle band of the percentile range.

Seriously, is this really their mission?

Re:  Currency Exchange Rate Oversight Reform Act of 2011

Dear Senators:

Thanks!  For years, our government has pursued a currency and trade policy that has subsidized your American consumers at the expense of our own here in China, and while we are unsure exactly why you would want to end this arrangement (we presume due to powerful lobby by your large manufacturers), we are happy that you are doing so….

A low yuan makes Chinese products cheap for Americans but makes imports relatively dear for Chinese.  So-called “dumping” represents an even clearer direct subsidy of American consumers over their Chinese counterparts.  And limiting foreign exchange re-investments to low-yield government bonds has acted as a direct subsidy of American taxpayers and the American government, saddling China with extraordinarily low yields and creating inflationary pressures.

Every single step China takes to promote exports is in effect a transfer of wealth from Chinese citizens to Americans, and we are tired of it.

Read it all.

On 9/11, I was sitting in the restaurant at the W hotel in Midtown Manhattan having breakfast with some bankers. I had recently been hired to see if I could make something out of a startup that was trying to manage aircraft parts sales and inventories over the web. My incredibly ill-timed pitch to the bankers was that the commercial aviation business, which had been somewhat in the doldrums, was on the verge of a turnaround. Oops.

My wife came down to breakfast to tell us something funny was going on in the news. We ended up going to one of the banker’s hotel rooms — he had a penthouse suite with a balcony from which we watched the now-famous and horrible events play out.

The rest of the day was odd to say the least. People on the street flinched whenever a plane flew over. The entire island emptied out, such that in the evening, we walked through Times Square and not a single care came through in 5 minutes. Someone was skateboarding in lazy circles, I suppose just because he could.

For us, 9/11 fortunately was only a hassle. We scrambled to find someone to watch our kids in Seattle, and found the last rent car in the city and ended up driving all the way back to Seattle from New York. We still made it back before air travel resumed.

Many of our friends were not so lucky. As both my wife and I were grads of the Harvard Business School, we knew scores of people who worked in the WTC. Over the coming weeks, word floated in of friends that had died that day, including our friend Steve who did not work there but got talked into going to a training session he really did not want to be at. I actually think of him many times, when I am asked to do tedious business trips I see not value in. I have learned to skip a lot of them. Life is too short.
