An article on Tuesday about a sweeping federal climate change report referred incorrectly to the availability of the report. "That's not a future prediction anymore". The government scientists found that "stronger evidence has emerged for continuing, rapid, human-caused warming of the global atmosphere and oceans".
That premise suggests that the Trump administration is stifling a damaging draft report - part of the congressionally mandated National Climate Assessment - with dire warnings about climate change.
"This is the most comprehensive science report that has been published outside of the auspices of the Intergovernmental Panel on Climate Change, to my knowledge", co-lead author Katharine Hayhoe of Texas Tech University told the BBC.
Report suggests U.S. is already feeling the impact of climate change Average temperatures throughout the United States have risen rapidly since 1980, according to a new report. "These are all physically very closely linked with high temperatures". "While it was not widely publicized, the report was uploaded by the nonprofit Internet Archive in January; it was not first made public by The New York Times".
But this is an unusual time, and what remains uncertain is whether the report now pass the test of an administration that has an unprecedented hostility to climate science and to some degree science itself. In the past, the reports have been published by the 13 agencies at globalchange.gov. But one of the most troubling findings in the draft report is that air and ground temperatures in Alaska and the Arctic are rising twice as fast as the global average. The East will get wetter, and the Southwest drier. Luckily, or so we were made to think, some courageous soul inside the bureaucracy bravely blew the whistle and gave a draft of the report to the Times, which promptly published it.
Atmospheric rivers that bring extreme precipitation to the West Coast, like the ones last winter that ended California's drought, are projected to increase in frequency, but will fall more as rain than snow, the report says.
While the findings in Thursday's report were limited to 2016, NOAA scientists said there's been little, if any, letup in climate trends this year.
The 2015 Paris Climate Agreement set a goal of capping warming at 1.5 degrees over the pre-industrial average.
Walsh said, whatever fears scientists might have, he's seen no political interference in the report to date.
As the draft federal climate report was being published, the Pacific Northwest was slowly emerging from a record heat wave and a brutal stretch of hot weather nicknamed "Lucifer" was taxing much of southern and eastern Europe.
"This has been alarming for a long time", Gleick said.
The US President has repeatedly dismissed man-made climate change as "a Chinese hoax" and he sent shockwaves through the global community when he announced the US would withdraw from the Paris Agreement. And that, as the scientific literature makes clear, would be the end of modern civilization as we know it.
Alley said the changes in the climate that have already occurred are small compared with what will happen if emissions are not reduced sharply.
