Sea ice extent, defined as the total area covered by ice of at least 15% concentration, is one of the most commonly used indicators of long-term Arctic sea ice conditions. The primary source of extent observations is the 46-year record (starting in 1979) derived from satellite-borne passive microwave sensors.

This satellite record tracks long-term trends, variability, and seasonal changes from the annual extent maximum in late February or March to the annual extent minimum in September. In recent years, minimum extents are ~50% of the values in the 1980s.

Chaos Inside FEMA as Death Threats Distract From Hurricane Response Internal documents show how online conspiracies and personal attacks disrupted FEMA during back-to-back hurricanes last year.

New docs obtained via FOIA reveal how the personal attacks to FEMA staff last hurricane season were much worse than previously known, including swatting & doxxing of officials.

Screenshot of text: These and dozens of other actions taken since Jan. 20 paint a clear picture: The Trump administration is going to war with established climate science. Mass firings, regulatory rollbacks, program closures, and funding cuts across agencies have compromised the nation’s ability to gather and assess data on climate change, reducing the amount of high-quality information that policymakers and business leaders can use to guide their decisions, potentially for years to come.

Trump Is Dismantling Climate Science at a Dangerous Pace The White House has blocked efforts to measure, respond to and fight global warming. That puts all Americans at risk.

The Trump administration is taking a "cluster bomb approach" to rolling back climate science and environmental policy and undertaken rouhgly 400 anti-science actions since January. It could take the US decades to recover what is being lost, and some things may be be permanently gone
