The US Navy will no longer distribute certain satellite readings, a move that will leave forecasters without important insights into storms’ strength and structure.

What’s going on is that the same microwave measuring instruments that are used to track hurricanes also are used to monitor sea ice, and they showed an ongoing loss of sea ice as a result of the warming caused by greenhouse gases that result from fossil fuel consumption. So the Trump administration decided to cut off access to make it harder to monitor sea ice.
