Fears Trump administration will overrule climate change report
Scientific researchers from 13 federal agencies who authored a report on climate change fear it may not be approved for release by the Trump administration because it contradicts assertions by the president and his colleagues that humanity’s contribution to climate change is uncertain. The report states that evidence of climate change “abounds”, and that thousands of studies have concurred that human activities "are primarily responsible for recent observed climate change". The National Academy of Sciences has already approved the draft.
WASHINGTON — The average temperature in the United States has risen rapidly and drastically since 1980, and recent decades have been the warmest of the past 1,500 years, according to a sweeping federal climate change report awaiting approval by the Trump administration.

The draft report by scientists from 13 federal agencies concludes that Americans are feeling the effects of climate change right now. It directly contradicts claims by President Trump and members of his cabinet who say that the human contribution to climate change is uncertain, and that the ability to predict the effects is limited.

“Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans,” a draft of the report states. It was uploaded to a nonprofit internet digital library in January but received little attention until it was published by The New York Times.

The authors note that thousands of studies, conducted by tens of thousands of scientists, have documented climate changes on land and in the air. “Many lines of evidence demonstrate that human activities, especially emissions of greenhouse (heat-trapping) gases, are primarily responsible for recent observed climate change,” they wrote.
