Russia is attempting to claim more of the Arctic seabed, an area rich in oil, gas and minerals. It’s also expanding shipping and reopening Arctic bases. Here are two things the U.S. can do about it.
We can learn about the spread of diseases through populations by studying naturally occurring instances of herd immunity. Avian cholera in the Canadian Arctic provides a useful case study.

The media often call unusually cold, snowy storms a ‘polar vortex.’ The real polar vortex isn’t coming down to visit the lower 48, but changes to the polar vortex can influence winter weather.
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.
The US is formally back in the Paris climate agreement as of today. As one of the world’s largest greenhouse gas emitters, it has a lot of work to do, with food security, health and safety at stake.
Arctic heat waves were once rare and unusual events. But as their intensity and frequency increase with climate change, their fallout could affect the north — and the planet — for decades to come.
This is the story of ‘Misha’, as I have come to know her. Both I and my research have been deeply affected by a polar bear I have never met face to face.
Climate change is thawing permafrost and increasing the risk of these accidents, and the region has fewer of the bacteria that can ‘clean up’ oil spills.
