Massive Government Report Says Climate Is Warming, Humans Are The Cause

"It is 'extremely likely' that human activities are the 'dominant cause' of global warming, according to the most comprehensive study ever of climate science by U.S. government researchers.

The climate report, obtained by NPR, notes that the past 115 years are "the warmest in the history of modern civilization." The global average temperature has increased by about 1.8 degrees Fahrenheit over that period. Greenhouse gases from industry and agriculture are by far the biggest contributor to warming.

The findings contradict statements by President Trump and many of his Cabinet members, who have openly questioned the role humans play in changing the climate."
