National Climate Assessment
By Dr. Tamara Dickinson A year ago today, hundreds of the country’s top climate scientists confirmed that climate change is affecting every region across America in the third U.S. National Climate Assessment (NCA) – the most comprehensive scientific report on domestic climate change impacts ever generated. Since then, communities, localities, and
