In this study, which was led by Oregan State University, funded by the US National Science Foundation's
Paleoclimate Program and just published in Science, researchers used «extensive sea and land surface temperature reconstructions»
of around 21,000 years ago — in stead
of the (late) Holocene temperature record that is mostly used.
The paleoclimatology community seems to be tightly coupled as indicated by our social network analysis, has rallied
around the [Mann] position, and has issued an extensive series

of which appear to support the conclusions
of MBH98 / 99... Our findings from this analysis suggest that authors in the area

of residence time having what I see as at least three problems: fallacious appeal to
paleoclimate, irrelevance
of average residence time per molecule, and neglect
of disequilibrium coefficients.
Based on
paleoclimate trends, scientists are putting the odds
of the U.S. Southwest sliding into a decades - long megadrought at
around 50/50.
