Nov. 23, 2018 – “Policymakers can no longer afford to dismiss or ignore the overwhelming scientific evidence of climate change. The science on climate is clear, and we must face the facts in order to address the risks. We welcome the 4th National Climate Assessment and the work of scientists at federal agencies, national labs and academic institutions who provide significant research findings that increase our understanding of how climate change is affecting the United States and the world. ”

“We will continue to implore decision-makers at all levels – local, state, regional and national – to use scientific evidence as they find opportunities for communities to respond effectively to climate change. The scientific community stands ready to help inform your choices.”

— Rush Holt, chief executive officer, American Association for the Advancement of Science (AAAS)
