The US has already experienced rapid and drastic warming since 1980, with recent decades the warmest of the past 1,500 years.
This, according to a leaked draft of a federal government climate change report, still awaiting approval by the Trump administration, and obtained by the New York Times’s Lisa Friedman.
The draft report, by scientists from 13 federal agencies, says Americans are “feeling the effects of climate change right now,” Friedman writes, adding that “scientists say they fear the Trump administration could change or suppress the report.
The draft report says: “Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans”.
Trump administration officials received a copy of the most recent fifth draft of the report several weeks ago, the Washington Post reports.
It obtained the third draft, but cites “people familiar with both versions” to say there is “no substantive difference”.
