A landmark report to be formally launched at the White House tomorrow will warn Americans that climate change is not a far-off, future doomsday event–it’s a clear and imminent danger. Compiled by over 240 leading scientists and experts, the National Climate Assessment (NCA) is a 1,300-page report that will guide the Obama administration on future climate and energy policies. According to The Guardian, this exhaustive study is “meant to be the definitive account of the effects of climate change on the US.”

“Climate change, once considered an issue for a distant future, has moved firmly into the present,” starts the draft version of the report in its introduction. The draft continues: “Americans are noticing changes all around them. Summers are longer and hotter, and periods of extreme heat last longer than any living American has ever experienced. Winters are generally shorter and warmer. Rain comes in heavier downpours, though in many regions there are longer dry spells in between.”

The NCA goes on to present and assess observations on the impacts of climate change from around the country, from water shortages on Native American tribal lands to the decreased yields of Iowa corn producers. The NCA also notes that the average temperature in the US has increased by about 1.5 Fahrenheit since 1895, with over 80 percent of that rise since 1980. As the first report to fully assess how the U.S. has been mitigating and adapting to climate change, the NCA is expected to play a large role in guiding Obama’s environmental agenda for the next two years.
