Global Warming Will Make People Dumber

I have just come across a book, Race Differences in Intelligence: An Evolutionary Analysis, which has given me something new to worry about. Global warming - if it lasts long enough - will cause the average IQ of the human race to decline.

Here is a bit from a review of the book.

The book's central finding: the world average IQ is no more than 90, and declines from north to south. An IQ of 90 is equivalent to the mental age of a White14-year-old. (Standardized IQ tests are normed to 100, the mental age of the average white 16-year-old.). Lynn also draws attention to the fact that a north-south IQ continuum has evolved, apparently through selection for survival in cold winters.
The danger is obvious. If the planet stays warm enough for long enough the average IQ in the cooler climates will decline. OTOH that could be a good thing for eliminating the disparities in wealth that are caused by intelligence differences. So in the long run global warming could lead to a more egalitarian world. But there is a small problem. Such a decline in average IQ may reduce the opportunities for women. What to do? What to do?

Well, I suppose I could follow Johnny Horton's advice and move North to Alaska. And I KNOW that I would much prefer Sarah Palin to my current bozo governor.

On second thought, maybe I will just stay here and read a different book.

Good evidence that universal education is worthless.
