A group of interested individuals (amateur climate enthusiasts) took serious issue with the mathematical/statistical techniques used by climate-scientists to reconstruct Antarctic temperatures in a 2009 peer-reviewed study. As it turns out, this group of amateurs were better versed in proper mathematical/statistical analysis than the experts, and they brought that specific expertise to bear on the 2009 temperature reconstruction study. Objectively, even AGW alarmists are praising their work!
The result of this new peer-reviewed study? The Antarctic climate is not this monolithic warming environment that the IPCC Climategate "experts" attempted to portray to the politicians and taxpayers in the 2009 study. Instead, like all other large regions of the globe, Antarctica exhibits areas of warming, cooling and temperature stability. [Ryan O’Donnell, Nicholas Lewis, Steve McIntyre, Jeff Condon (2010)]
Based on this new analysis (O’Donnell et al.), modern temperature trends are no threat to the continent-sized ice sheets. Antarctica is soooo cold, a half-degree per decade, either way, is of zero significance.
The image on the left indicates the corrected decadal temperature trends, which are miniscule: from -0.5 degrees to +0.5 degrees per decade. The image on the right is from the 2009 study, designed to show significant Antarctic warming across the entire continent. (click on image to enlarge)
