Antibiotic resistance is common in bacteria where there's a large human population and poor sanitation. For the first time however, it's been found in the remote Arctic.
All too often the Arctic region is portrayed as an area on the cusp of military invasion. This is an easy narrative to sell. But is there really a new Cold War coming?

New trade routes and a wealth of natural resources are becoming increasingly available – and everyone wants a part of them.
Extreme climatic events are harming plant communities in the Arctic. The resulting colour change is bad news for the region's carbon storage.

Climate change is shrinking Arctic sea ice and opening the region to ship traffic. Whales, seals and other marine mammals could be at risk unless nations adopt rules to protect them.
Bombarding people with scientific information has little effect. Something else is needed to jolt us out of our current climate trajectory.
2016’s warm winter meant not enough snow for the start of the Iditarod sled dog race in Anchorage, so it was brought by train from 360 miles north.
For everyone from traditional hunters to the military, the National Park Service to the oil industry, climate change is the new reality in Alaska. Government, residents and businesses are all trying to adapt.
Animals in the western Arctic have higher levels of mercury in their bodies than those in the eastern Arctic.
A new study demystifies regional differences in mercury levels in marine animals in the Canadian Arctic.

New shipping opportunities are opening up in the Arctic as sea ice continues to recede. But travel is still dangerous and the region isn't equipped to deal with more vessel traffic.
Since 2005, the Barents Sea has become too warm for sea ice to exist south of the Polar Front.
