Scientists discover a tipping point that took place in 2000, where El Niño’s effect on sea ice loss in Siberia was amplified.

Purposefully sinking boreal trees could help lock away carbon for millennia or longer, but the audacious plan comes with risks of its own.

An unusually brutal winter storm is set to pummel more than 160 million Americans from Friday, as a stretched "polar vortex" sends a devastating blast of Arctic air, bringing heavy snows and freezing rains.

Earlier research has shown that the Arctic is warming significantly faster than the rest of the planet, leading to reductions in ice cover as well as the weather changes mentioned here.

Trump’s anti-climate policies have already been damaging to the Arctic and global climate protection. Now his deeply misguided plans for Greenland and the rest of the Arctic, if allowed to occur, would increase the chances of disastrous,

In the tropics, the border between troposphere and stratosphere—the tropopause—sits at around 20km, far above any normal aircraft’s ceiling. But its height drops as you move away from the equator. By the time you get to 60°N and 60°S it is low enough for airliners to rise above it.

Organic matter carried in rivers to the Russian part of the Arctic Ocean may be creating more clouds and keeping the region cooler, a new study has found.
