A new study shows how thawing permafrost and intensifying storms will change how water moves into and through Arctic rivers.

Cold snaps can affect everyday services and infrastructure, putting lives at risk.

Houthi attacks on ships in the Red Sea have disrupted trade between Asia and Europe – could ships cross the Arctic instead?

While the world can expect fewer severe cold events as average temperatures rise, people still need to be prepared for wintery blasts.

Small unmapped lakes in the Arctic are far less abundant than previously thought, which researchers say is good news for methane emissions.

The early heat melted snow and warmed rivers, heating up the land and downstream ocean areas. The effects harmed salmon fisheries, melted sea ice and fueled widespread fires.

Thawing permafrost in the far north is an inviting prospect for invertebrate burrowers.

Stratospheric clouds over the Arctic may explain the differences seen between the polar warming calculated by climate models and actual recordings, according

Deeper snowpack than normal in some parts of the Arctic is driving the thawing of long-frozen permafrost carbon reserves, researchers report.
