Washington, D.C., May 6, 2014, — Today, we released the third National Climate Assessment report, by far the most comprehensive look ever at climate change impacts in the United States.
Based on four years of work by hundreds of experts from government, academia, corporations, and public-interest organizations, the Assessment confirms abundant data and examples that climate change isn’t some distant threat — it’s affecting us now.
