Scientists and Economists' Call to Action
The U.S. Scientists and Economists' Call for Swift and Deep Cuts in Greenhouse Gas Emissions is a call to our nation's leaders to require immediate, deep reductions in heat-trapping emissions that cause global warming. The statement is endorsed by more than 1,700 scientists and economists with expertise relevant to our understanding of the scientific and economic dimensions of climate change, its impacts, and solutions. This marks the first time leading U.S. scientists and economists have joined together to make such an appeal.
