The U.S. government has begun laying off staff at NOAA as part of President Donald Trump’s ongoing efforts to shrink the federal workforce and roll back the government’s climate-related spending.

The National Oceanic and Atmospheric Administration houses key groups like the National Weather Service. Experts warn the consequences of employee cuts could be drastic.

The cuts spared "only some" specialists at its National Weather Service, according to a congressional aide speaking on condition of anonymity. Layoffs at NOAA, a top weather and climate agency, come as climate change causes more intense and frequent weather and climate extremes.
