The landmark new report, which comes from more than a dozen federal agencies and is known as the National Climate Assessment, includes more than 1,000 pages and the work of more than 300 authors breaking down climate change’s impacts in specific regions across the country, touching on everything from agricultural changes to sea-level rise to health effects.


The changes highlighted in the report “threaten the health and wellbeing of the American people” and “further disrupt many areas of life, exacerbating existing challenges and revealing new risks,” says David Easterling, a report author and scientist at the National Oceanic and Atmospheric Administration (NOAA).

The report is the second volume of a non-partisan work of science mandated by Congress to inform policymakers about the reality of global warming, and it represents a sweeping view of the scientific consensus. “Any remaining debate on the reality of climate change is over,” says Lou Leonard, SVP for climate change and energy at the World Wildlife Fund. “The Bush, Obama and now Trump Administrations have all published reports showing the current and future impacts to the United States from climate change.”
