On Thursday, the USGS shared a new analysis just released by the USA-National Phenology Network, which the agency helps to fund, showing that an early spring has already swept through the Southeast and is continuing to work its way across the country. As the agency points out, the new analysis reaffirms a fact scientists have known for at least a decade now — that “climate change is variably advancing the onset of spring across the United States.”
For the record, experts have been sounding the alarm about climate change and a warming climate since at least 1988:
Exactly 20 years ago, on June 23, 1988, James Hansen of the NASA Goddard Institute for Space Studies testified before a Senate committee that he could state with "99 percent confidence" that a recent, persistent rise in global temperature was occurring, and had long been expected. That landmark statement, and the dawn of the global warming discussion, was covered by Andy Revkin, then a DISCOVER senior editor and now an environmental reporter for The New York Times.The award-winning Revkin now writes for Pro Publica.
How long we will hear from the USGS on climate change is what's debatable.
The USGS is a science arm of the US Department of Interior. Climate change denier Donald Trump has nominated a Montana congressman and climate change waffler to serve as Interior Department Secretary. His confirmation vote is pending.
