Gerda wanted a scrap so here it is. :-)
Normally, I put things like this on my blog, but that typically is only read by porn/Viagra/Eastern Bloc Mail Order Bride e-mail address harvesters so I thought I would provide it here instead.
Eos, for those that don't know it by name, is the weekly newsletter of the American Geophysical Union. Articles in Eos are peer-reviewed and written at a general level where "general" means easily understood by anyone with a degree in some form of earth science or physics or chemistry. They are well-worth tackling for the advanced layman.
Ok, The December 2, 2008 issue of Eos (vol. 89, No. 49), on Page 501 (front page) has an article titled "Pliocene Role in Assessing Climate Impacts." It's a very interesting article drawing analogies between what is known about the warm period 3 million years ago and the warming projected for 2100. (I would provide a link, but Eos is a stickler for access so it wouldn't do any good.)
There is also an interesting article in the December 28, 2008 issue (vol. 89, No. 53), "Does Global Warming Influence Tornado Activity?" (Definite maybe, according to the article.)
