The agency that leads most of the government’s work on ocean and coastal health as well as climate research is one among those being targeted by Trump.

The Trump administration has its government-shrinking sights set on the National Oceanic and Atmospheric Administration, where around 800 employees have been tapped for termination, according to two sources close to the agency.

Experts caution the groups play a key role in ensuring agencies use the best available science in their decision making.

The National Oceanics and Atmospherics Administration is responsible for providing weather watches and warnings, monitoring and studying Earth's climate, as well as operating weather satellites and protecting marine life.

Federal employees who monitor and forecast the nation’s weather and climate have been hit with a wave of mass firings.

A Boston meteorologist was one of hundreds of federal NOAA employees on probationary status fired on Thursday.

NOAA previously fired 880 employees on Feb. 27, the majority of which were probationary staff with fewer than two years in their positions.

Together with recent firings and resignations, the new cuts could hamper the National Weather Service’s ability to produce lifesaving forecasts, scientists say.

The potential closures come as the General Services Administration looks for opportunities to sell government buildings it says may be needed.

The Trump administration’s layoffs continue to careen down a path of destruction through federal agencies — last week touching down on a critical National Oceanic and Atmospheric Administration office on the Monterey Peninsula that is on the front lines of tracking and helping to mitigate the effects of climate change.
