Lake sediment in the Tibetan Plateau suggests permafrost at high elevations is more vulnerable than arctic permafrost under projected future climate conditions.

Sea ice is thinning at an alarming rate. Snow is shifting to rain. And humans worldwide are increasingly feeling the impact of what happens in the seemingly distant Arctic.

Alaska is warming faster than any other U.S. state, and that’s causing problems, a team of bridge engineers and social scientists explains. The infrastructure bill in Congress would offer some help.

Alaska is warming faster than any other U.S. state. That’s causing problems for river crossings, as a team of bridge engineers and social scientists explains.

Earth observation satellites can measure millimetre changes in sea level and track deforestation in near-real time.

New research shows that permafrost contains huge amounts of particles that make it easier for cloud moisture to freeze. Thawing permafrost is releasing these ice-nucleating particles.

Peat beds around the world hold huge quantities of carbon and keep it from warming the planet. But rising temperatures and over-use could turn them from a brake on climate change into an accelerant.

Three scientists describe the fieldwork they've had to delay in 2020 because of the pandemic. These are setbacks not just for their careers, but for the body of scientific knowledge.

The Zimovs want to restore the prehistoric 'mammoth steppe' ecosystem and see if it slows down – or even reverses – melting permafrost.
