In 2008, at the request of the U.S. Congress, the U.S. National Research Council organized a series of studies designed to create recommendations on what should be done about climate change. Dr. Chameides is vice chair of the Committee on America’s Climate Choices, which oversaw the studies whose results were released in May 2011.
