Dueling Studies at NASA, and Other Warmist News

A group of 25 retired NASA scientists has released a report (PDF file) throwing lots of cold water on catastrophic global warming scenarios, and it’s probably important that emphasize that they are “retired” NASA scientists, because it they were still active in the agency they might be getting stern looks, and assigned to smaller offices, by the higher ups in space command.  From the summary:

We have concluded that, at most, 0.7 degrees C AGW has occurred since 1850, but that it is possible that some of this observed warming was caused by naturally occurring cycles of global temperature variation. Other small amounts of global warming since 1850 were caused by an increase in solar irradiance. The naturally occurring global temperature cycles are clearly evident in the 8000 years of climate data before the dawn of the Industrial Age. Earlier, much greater changes in global temperature were exhibited during the ice age cycles, and are destined to occur again as the current Holocene ice age cycle unfolds.
