Scientists from 13 agencies contradict Trump on climate


Scientists from 13 agencies contradict Trump on climate

That directly undercuts statements by Trump and his Cabinet casting doubt on whether the warming observed around the globe is being primarily driven by man-made carbon pollution.

Since 2014, Alaska has seen three of its warmest years ever and record low sea ice. That is a congressionally mandated analysis that seeks to build on the existing science and provide a snapshot of the current state of climate change. The Times reported that scientists leaked them a copy of the report, "which has not yet been made public", because they were "concerned that it would be suppressed". Environmental Protection Agency chief Scott Pruitt and Energy Secretary Rick Perry have championed the formation of a "red-team, blue-team" exercise where climate-change skeptics would publicly debate mainstream climate scientists. That assessment calls into question the wisdom of Trump's environmental and energy policies, which seek to boost USA production and consumption of fossil fuels even as the world's other leading economies promote cleaner sources of energy.

Last year surpassed 2015 as the warmest in 137 years of records and was the third consecutive year a new record high was achieved, according to the report released Thursday afternoon. As others have pointed out - and The New York Times should have noticed - drafts of this report have been published and made widely available online months ago during the public comment period.

A new government report warns that regions across the US are feeling the effects of rapid climate change, with some of the greatest impacts in Alaska and the Arctic. "If the report is approved, then it is just a matter of logistics before it is published". One such gas, carbon dioxide, averaged a global concentration of 402.9 parts per million for the year, passing the 400 ppm threshold for the first time in more than 800,000 years, NOAA said. Thousands of studies conducted by tens of thousands of scientists around the world have documented changes in surface, atmospheric, and oceanic temperatures; melting glaciers; disappearing snow cover; shrinking sea ice; rising sea level; and an increase in atmospheric water vapor.

And "greenhouse gasses" gets the tongue-twister, "build soil organic matter, increase nutrient use efficiency".

"Every increment in warming is an increment in risk", said Field, who wasn't part of the report but reviewed it for The National Academy of Sciences.

The Climate Movement calls itself a coalition dedicated to making local changes.

Last week, the Trump administration issued its first written notification to the United Nations that it intends to withdraw from the Paris climate accord.

In March, the Washington Post obtained a budget memo showing that the Trump administration meant to slash NOAA funding by 17 percent, a cut that former NOAA chief scientist Rick Spinrad said would "jeopardiz [e] the safety of the American public".

In fact, one of the scientists who signed the report, Bob Kopp, stated on Twitter, "It's not clear to me what the news is in this story; posted draft is in public review draft from Dec".

"These comments reflect the utterances of someone who either doesn't have the faintest understanding of the science, or has total contempt for scientific truth", Michael Mann, climatologist, geophysicist and director of Penn State's Earth System Science Center, told Gizmodo.
