- -New Analysis of 2 Million Years of Data Suggests Bad Outcome for Life on Earth (Nature.com)
"A comparison of the new temperature reconstruction with radiative forcing from greenhouse gases estimates an Earth system sensitivity of 9 degrees Celsius (range 7 to 13 degrees Celsius, 95 per cent credible interval) change in global average surface temperature per doubling of atmospheric carbon dioxide over millennium timescales. This result suggests that stabilization at today’s greenhouse gas levels may already commit Earth to an eventual total warming of 5 degrees Celsius (range 3 to 7 degrees Celsius, 95 per cent credible interval) over the next few millennia as ice sheets, vegetation and atmospheric dust continue to respond to global warming."
Editor's Note: A simple statement of the author's conclusion is that if current greenhouse gas levels stay the same as they are now for the next few thousand years, we can expect that global temperatures may rise 5 dgrees Celsius. Most climatologists predict that a rise in global temperature of 5 degrees Celsius would be catastrophic. 09-06
