Polar bears in the Barents Sea are staying fat despite rapid sea ice loss
Polar bears can struggle to adapt to climate change. Bears on Svalbard may be surviving on land prey and seals — but scientists warn it may not last.

An underwater volcano off Oregon didn’t erupt in 2025 after all. Why not?
Data from Axial, the most-monitored underwater volcano, are helping geophysicists hone eruption predictions. For Axial, 2026 is their next bet.
