Pollution over the Tibetan plateau linked to sea ice loss in the Arctic

New research suggests an atmospheric connection between Arctic sea ice melt and anthropogenic aerosol pollution over the Tibetan Plateau.


Thawing permafrost puts global climate warming in spotlight

The Arctic is warming more than twice as fast as the rest of the world, and some scientists believe that thawing permafrost - ground frozen since the last Ice Age - is about to release enormous amounts of climate-warming emissions.


Arctic expedition's dress code raises concerns about sexism in science

The scientific institute leading the trip denied that its policy had been applied to a specific sex, saying, “Women and men participate in our polar expeditions as equals.”

Greenland could lose more ice this century than it has in 12,000 years

The warming climates of the Arctic and the tropics squeeze the mid-latitudes, where most people live

For humans, the mid-latitudes are Earth's climate sweet spots, where much of civilization, including cities and key food production areas, have developed. But those zones are increasingly being pummeled by climate change from both the north and south.


Climate disruption is now locked in. Next moves will be crucial

The Times spoke to two dozen experts who said decisions made now would spell the difference between a difficult future and something far worse.
