Another error in the influential reports from the Intergovernmental Panel on Climate Change (IPCC) reports has been identified. This one concerns the rate of expansion of sea ice around Antarctica.
While not an issue for estimates of future sea level rise (sea ice is floating ice which does not influence sea level), a significant expansion of Antarctic sea ice runs counter to climate model projections. As the errors in the climate change “assessment” reports from the IPCC mount, its aura of scientific authority erodes, and with it, the justification for using their findings to underpin national and international efforts to regulate greenhouse gases.
Some climate scientists have distanced themselves from the IPCC Working Group II’s (WGII’s) Fourth Assessment Report (AR4), Impacts, Adaptation, and Vulnerability, prefering instead the stronger hard science in the Working Group I (WGI) Report—The Physical Science Basis.…
How many times have you been told that the debate on the science of climate change is “over”? Probably almost as many times as Al Gore has traveled in private jets and limousines to urge audiences to repent of their fuelish ways.
Although tirelessly intoned by politicians, major media, advocacy groups, academics, and even some Kyoto critics, the “debate is over” mantra is just plain false. The core issues of climate-change attribution, climate sensitivity, and even anthropogenic detection remain very much in play.

The world has warmed overall during the past 130 years, as evidenced by melting glaciers, longer growing seasons, and both proxy and instrumental data. However, the main era of “anthropogenic” global warming supposedly began in the mid-1970s, and ongoing research by retired meteorologist Anthony Watts leaves no doubt that in recent decades, the U.S.…
