A national round of workshops for researchers and a top-level dialogue on the financial risks of climate change are among the new initiatives.

Reducing greenhouse gas emissions or adapting to their consequences are the best-known strategies for dealing with climate change, but geoengineering strategies deserve closer attention, experts said at a Capitol Hill briefing.

Researchers searching for ways to be effective ambassadors for U.S. science policy—and to prevent crippling cuts to the federal R&D budget—must learn the challenges facing Congress in order to become successful advocates, according to a guide published by AAAS.

A panel of distinguished scientists, appearing at a Capitol Hill briefing organized by AAAS, surveyed a broad range of data and research that affirm a clear human link to global climate disruptions.

While climate change science has been subject to sometimes vitriolic attacks in recent months, the briefing took a tempered tone. The speakers emphasized the value of bucking conventional scientific wisdom, but showed that the arguments commonly used by climate change skeptics tend to fall apart when subjected to close scrutiny.

The percentage of Americans who believe global warming is real dropped slightly from 80% in 2008 to 75% late last year, still a robust majority that reflects a continued agreement with the conclusions of climate science, a leading specialist on survey research told a Capitol Hill briefing co-sponsored by AAAS.
