Washington, May 8 (RHC)-- A new report warns human-driven climate change is having dramatic health, ecological and financial impacts across the United States.

The White House’s "National Climate Assessment" is reportedly the largest, most comprehensive U.S.-focused climate change study ever produced. It details how the consequences of climate change are hitting on several fronts — rising sea levels along the coasts, droughts and fires in the Southwest, and extreme rainfall across the country.

President Barack Obama’s science adviser, John Holdren, said climate change is no longer a future threat, but happening in the present. Holdren said: "The contents confirm that climate change is not a distant threat. It is affecting the American people already. And climate disruptions to water resources and agriculture have been increasing."

The report warns that unless greenhouse emissions are curbed, U.S. temperatures could increase up to 10 degrees Fahrenheit by the end of the century.
