Leaked report speaks volumes

-

Adraft federal report on climate change that went public Monday contains little in the way of new science, and although its language is unequivoca­l, it merely confirms what has been obvious to so many scientists for so long: Human activity is increasing global temperatur­es, leading to potentiall­y catastroph­ic climate change. So what’s the news? That federal scientists so feared the final report would be gutted or suppressed by the climate change-doubting Trump administra­tion that they leaked it.

President Donald Trump’s refusal to accept the obvious about the planet’s changing climate is more than embarrassi­ng. His stance sets the U.S. at odds with nearly every other nation on Earth, all but two of which are part of the 2015 Paris agreement to try to cap global warming to no more than 2 degrees Celsius over pre-industrial levels by significan­tly reducing greenhouse gas emissions.

Hitting the Paris agreement’s target will require a rapid pivot away from burning fossil fuels in favor of renewable energy. But Trump’s policy is to not only drill for more oil and gas and resurrect the coal industry (whose product is the worst offender among fossil fuels), but also to assert the U.S. as the dominant producer of the very energy sources that threaten radical upheaval in how humans live on Earth. That’s as wrong-headed as it is dangerous.

In leaking the report (obtained by The New York Times), scientists within the government ensured that their work would reach the public, serving as a check on the administra­tion in case it did indeed try to trump science with politics. In that sense, the leaked report helps isolate the president, his fellow doubters and his allies, such as Environmen­tal Protection Agency Director Scott Pruitt and Interior Secretary Ryan Zinke, whose combined regulatory moves would reduce curbs on emissions and set the stage for accelerate­d drilling and mining on federal lands.

One area where the leaked report, part of the congressio­nally required quadrennia­l National Climate Assessment, breaks new ground is in so-called attributio­n science. In the past, scientists have been reticent to tie specific severe weather events to overall climate change. But the report says scientists are now able to draw some direct connection­s with varying degrees of certainty between climate change and events such as heat waves in Europe in 2003 and Australia in 2013. It also links humanprope­lled climate change with a decrease in the number of cool nights across the United States since the 1960s and an increase in the number of warm days since the 1980s.

“It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century,” the report says. “For the warming over the last century, there is no convincing alternativ­e explanatio­n supported by the extent of the observatio­nal evidence.”

The changes are real and the future risks potentiall­y catastroph­ic. The whole world knows it, and the vast majority of the world is trying to address it. That Trump is not, and that government scientists feel the needs to join “deep state” actors in leaking their findings in fear of what the president might do against the nation’s best interests, is damning.
