Sorry to butt in... I just re-joined the PDML after a lengthy break but I've been looking into this subject lately... Here's something to read: http://books.nap.edu/catalog/11676.html#toc That's a report from the National Academy of Sciences requested by Congress back in the late '90s. They released the report back at the end of summer. For some reason when I tried to read it just now the book section links are dead. If the links start working again you can read page 5 of the overview that they predict a 2-6 degree Celsius (3.6-11 degrees F) increase in global temperature this century. According to the charts that's unprecedented, at least over the last 2000 years. After some more web searching, here's the quote "Overview The Earth warmed by roughly 0.6°C (1°F) during the 20th century and is projected to warm by an additional ~2-6°C during the 21st century" Some more searching found this PDF (the quote is on pg. 19 of the PDF, pg. 5 of the document): http://www.house.gov/science/hot/climate%20dispute/NAS%20full%20report.pdf So it looks like 10 degrees F, while near the upper limit, is not out of the question. -Mark > keith_w wrote: >> TEN degrees?
