Dozens of similar rallies were held across the country on Friday, including one in Washington, D.C., which drew more than 1,000 people.

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.

The National Oceanic and Atmospheric Administration (NOAA) began the process of firing hundreds of probationary workers Thursday, the latest mass job cuts within federal agencies, three sources with knowledge of internal operations told The Hill.

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.

Open letter from National Oceanic and Atmospheric Administration alumni: As former employees of the National Oceanic and Atmospheric Administration, we are writing to request your support for the dedicated professionals at NOAA who serve our nation tirelessly every day.

NOAA is tasked with everything from weather monitoring to researching climate change and recent layoffs will most likely impact projects in South Carolina.
