P.S. A friend points out:

Check out the USA Today graph accompanying the AP story on the international global- warming report. It makes it appear that the earth’s temperatures have been shooting upward. But upon closer examination, it only shows an increase of 1.2 degrees—over the last 150 years. 1860, according to the chart, is when “accurate measurements began.” Really? They could accurately measure the temperature, around the globe, to the tenth of a degree, in 1860? And as accurately as we can today with satellites?
When you have to stretch something that far, it’s usually best to start over.
