Paleoclimate Record Points Toward Potential Rapid Climate Changes (December 8, 2011)

This report summarises records from which one can infer ancient climates and corresponding ice and sea level changes. The current rate of rise in atmospheric CO2 is roughly 10,000 times the rate of past naturally occurring fluctuations, calling for the utmost alarm and concern over expected nonlinear feedbacks in ice cover and sea levels, even within a 2-degree Celsius maximum temperature increase. Co-author James Hansen of NASA is quoted as saying: “The paleoclimate record reveals a more sensitive climate than thought, even as of a few years ago. Limiting human-caused warming to 2 degrees is not sufficient …It would be a prescription for disaster.”

Americans’ Knowledge of Climate Change (October 12, 2010)

This Yale study, albeit based on polling methods which have their critics, indicate a significant lack of basic knowledge on anthropogenic climate change, but a large majority endorsing mass education.

State of the Climate in 2009 (August 3, 2010)

“Global average surface and lower-troposphere temperatures during the last three decades have been progressively warmer than all earlier decades, and the 2000s
(2000–09) was the warmest decade in the instrumental record. This warming has been particularly apparent in the mid- and high-latitude regions of the Northern Hemisphere…” Numerous variables and phenomena are tracked and described.

Report Calls for Coordinated Information on Climate Change (July 23, 2010)

The Copenhagen Climate Conference highlighted concerns about the willingness of major governments to tackle climate change urgently. In this news item, a report by the National Research Council requested by the U.S. Congress states: “Federal policies should not unnecessarily supersede measures already being taken regionally or locally…”. While calling for “reliable data coordinated through climate services and a greenhouse gas monitoring and management system to provide timely information tailored to decision makers at all levels” this report, subsumed under a program called America’s Climate Choices also calls for “urging federal agencies to support training for researchers on how to communicate complex climate change information and uncertainties to different audiences”.

Revised MIT climate model sounds alarm. New analysis shows warming could be double previous estimates (May 20, 2009)

A summary of a groundbreaking modeling effort from MIT in 2009, that incorporated economic factors into climate projections. “The new projections… indicate a median probability of surface warming of 5.2 degrees Celsius by 2100, with a 90 percent probability range of 3.5 to 7.4 degrees. This can be compared to a median projected increase in the 2003 study of just 2.4 degrees. The difference is caused by several factors rather than any single big change. Among these are improved economic modeling and newer economic data showing less chance of low emissions than had been projected in the earlier scenarios.”
