On December 16, 2025, the National Oceanic and Atmospheric Administration released the 2025 Arctic Report Card. Now in its 20th year, the Arctic Report Card (ARC) 2025 provides a clear view of a region warming far faster than the rest of the planet. Along with reports on the state of the Arctic’s atmosphere, oceans, cryosphere, and tundra, this year’s report highlights major transformations underway—atlantification bringing warmer, saltier waters northward, boreal species expanding northward into Arctic ecosystems, and “rivers rusting” as thawing permafrost mobilizes iron and other metals. 

On December 15, 2025, the National Science Foundation (NSF) announced its organizational realignment, with a new organizational chart. Follow the link below to learn more.
