The White House released the most comprehensive U.S.-focused climate science assessment ever conducted on Tuesday. It makes clear that global warming is no longer a phenomenon that will rear its ugly head in a far-off time and place. Instead, it is affecting everyone in the U.S. already, be it a farmer in Oklahoma dealing with heat waves and drought, or a coastal resident in New York City, still recovering from Hurricane Sandy's flooding.
Here are some of the report's key findings, in graphics.
Average U.S. temperatures have increased by between 1.3 and 1.9 degrees Fahrenheit since 1895. The country may be in for another 10 degrees Fahrenheit of warming by 2100, depending on the rate and magnitude of greenhouse gas emissions. Warming has affected every region of the country, especially since 1970.
Warming ocean temperatures and melting ice sheets are causing sea levels to rise, threatening coastal cities such as Miami, Florida, and Boston, Massachusetts, with increased coastal flooding during high tides and storm surge events.
The Northeast and Midwest are getting wetter and have seen a startling rise in extreme precipitation events. In other words, when it rains or snows, it really rains or snows.
But the Southwest is getting drier, hotter and is seeing a sharp uptick in large wildfires.
A tighter water supply will affect the lives and economies of nearly 60 million people in the Southwest, as population growth continues but water becomes more scarce.
Today's oceans look almost nothing like what people were used to throughout human history, as carbon dioxide emissions make the ocean more acidic, warmer and with reduced seasonal sea ice.
Climate change is already affecting agricultural production in the U.S., and may significantly curb the yields of some important crops. Many climate variables affect agriculture, from the number of dry days to the length of the frost-free season.
