Scientists Fear Trump Will Dismiss Blunt Climate Report – The New York Times

By Garry Rogers @Garry_Rogers

GR: The Final draft of U. S. Congress mandated climate report by 13 agencies is complete. Probably fearing suppression by the Trump administration, anonymous sources leaked the final draft of the report. I introduce the New York Times story on the report below. You can download the full PDF report here: Final-Draft-of-the-Climate-Science-Special-Report.

The report is detailed and factual, but agonizingly indirect in its warnings. Nevertheless, the report does state that harmful climate impacts have begun. One danger that the report makes clear is that there is much uncertainty about responses to the increasing extreme weather events, and about how many positive feedbacks–self-perpetuating cycles–might develop.

Lisa Friedman– “The report directly contradicts Trump administration claims about global warming and concludes that temperatures have risen rapidly since 1980.”

“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, which has not yet been made public, 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. A copy of it was obtained 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.

“The report was completed this year and is a special science section of the National Climate Assessment, which is congressionally mandated every four years. The National Academy of Sciences has signed off on the draft report, and the authors are awaiting permission from the Trump administration to release it.

“One government scientist who worked on the report, Katharine Hayhoe, a professor of political science at Texas Tech University, called the conclusions among “the most comprehensive climate science reports” to be published. Another scientist involved in the process, who spoke to The New York Times on the condition of anonymity, said he and others were concerned that it would be suppressed.” (Continue reading.)
