Climate change will reduce U.S. GDP by 10 percent by the end of the 21st century

In the New York Times on Nov. 19, 2018:

"Reports of the threats from a warming planet have been coming fast and furiously. The latest: a startling analysis from the Intergovernmental Panel on Climate Change predicting terrible food shortages, wildfires and a massive die-off of coral reefs as soon as 2040, unless governments take strong action."

And the New York Times on Friday, Nov. 23:

"A major scientific report issued by 13 federal agencies on Friday [today] presents the starkest warnings to date of the consequences of climate change for the United States, predicting that if significant steps are not taken to rein in global warming, the damage will knock as much as 10 percent off the size of the American economy by century’s end.

The report, which was mandated by Congress and made public by the White House, is notable not only for the precision of its calculations and bluntness of its conclusions, but also because its findings are directly at odds with President Trump’s agenda of environmental deregulation, which he asserts will spur economic growth."

"...in direct language, the 1,656-page assessment lays out the devastating effects of a changing climate on the economy, health and environment, including record wildfires in California, crop failures in the Midwest and crumbling infrastructure in the South. Going forward, American exports and supply chains could be disrupted, agricultural yields could fall to 1980s levels by midcentury and fire season could spread to the Southeast, the report finds."

CNN reported the same day about the same publication, saying that it "delivers a dire warning about climate change and its devastating impacts, saying the economy could lose hundreds of billions of dollars — or, in the worst-case scenario, more than 10% of its GDP — by the end of the century."

"Coming from the US Global Change Research Program, a team of 13 federal agencies, the Fourth National Climate Assessment was put together with the help of 1,000 people, including 300 leading scientists, roughly half from outside the government.

It's the second of two volumes. The first, released in November 2017, concluded that there is "no convincing alternative explanation" for the changing climate other than "human activities, especially emissions of greenhouse gases.""
