Trump Admin Decommissions Sea Ice Data That Warned of Arctic Climate Change

"Cuts at the National Oceanic and Atmospheric Administration are now degrading the datasets used to monitor the most rapidly warming parts of the planet. More such moves are coming, NOAA has warned."

"Key datasets used to monitor the impacts of climate change in the Arctic have emerged as the latest victim of cost-cutting by the Trump administration at the National Oceanic and Atmospheric Administration.

The National Snow and Ice Data Center (NSIDC), based at the University of Colorado Boulder, announced Tuesday that NOAA was ending its support for data products that document the extent and thickness of sea ice, the accumulation of snow and the retreat of melting glaciers. “As a result, the level of services for affected products below will be reduced to Basic—meaning they will remain accessible but may not be actively maintained, updated, or fully supported,” the center noted.

This blindsided scientists who use the NSIDC’s data. “That’s incredible. Let us walk blindfolded and not gather any information about our surroundings,” said Eric Rignot, a glaciologist at the University of California, Irvine, when informed of the decision by Inside Climate News.

For now, the NSIDC datasets are not disappearing. Some are updated by automated data feeds—for sea ice, the data comes from orbiting satellites. But without ongoing support from NOAA, any technical glitches will take longer to fix, and the NSIDC will struggle to support any users who need help."
