Every year since 2015, the Bering Sea has melted out earlier than in every year before 2015. If heat is killing animals, scientists have yet to pin down exactly how it is doing so.
Following another year of stark climate impacts in the Arctic, scientists warned Tuesday of a new scourge hitting the region: marine trash. With the region warming twice as fast as the rest of the world, sea ice that has long blanketed the Arctic Ocean is disappearing, opening new routes to shipping.
As sea ice off Alaska continues its long-term vanishing trend, two seal species that depend on ice may be showing the effects in their bodies. Ribbon seals, distinctive for their black-and-white striped patterns on their fur, and spotted seals, known for their speckled coats, became thinner over time.
Disaster funds are reserved for single events, and storms that collectively cause much damage aren't often individually large enough to count as disasters.
Arctic sea ice last month reached its greatest extent for the season, and it was the lowest in the satellite record. Now researchers say that ice is also younger and thinner than it once was.
