A polar bear was drawn to the Hope Dog Sled Race in Chukotka, Russia, an unusual event for the area. It is the third recent visit of a bear to the village. In size and build, the polar predator is similar to the same bear thatdisturbedlocal residents on the night of March 28.

A city building in Little Diomede, Alaska, slid off its foundation, threatening the structural integrity of adjacent buildings and critical services, with the community seeking immediate assistance.

John Ahkvaluk , 56, a polar bear guard revealed that this is not a good sign for the village. It’s the first time in several years that bears come at this time of the year. “It’s a warning that they got no food out there and they came looking for it here,” he said. After the incident, Luchie Manlangit, the school principal, and I invited John Ahkvaluk to talk to the kids and to share some protocols if polar bear will come around again.

Two more Russian LNG tankers made history earlier this month passing through the North Sea Route, which extends along the northern coast of Russian Asia, in late January, the latest commercial ship

One of three propulsion units on the tanker “Nikolay Yevgenov” was damaged on January 16 as the vessel approached the Bering Strait. After having sailed with a speed of about 9 knots from Sabetta, the tanker suddenly slowed to 3 knots.

Last week, a 908-foot Russian tanker carrying liquified natural gas passed south through the Russian side of the Bering Strait, with two more to follow. The ships are traversing the northern coast of Siberia, called the North Sea Route, in the middle of January with no icebreaker escort, an unprecedented event that may hint at the future of the region as climate change alters global commerce.

The “thermal curtain” is another expression for “cold pool” that acts as a barrier to keep some species—pollock and Pacific cod, for example — from migrating across the eastern Bering Sea shelf and northward toward the Bering Strait. For the first time in 37 years of surveying the Bering Sea, we could not find the cold water barrier.

Recent storms and warm seas melted a vast stretch of ice in the Bering Sea, leaving some islands surrounded by water when they should be locked in ice.

Last week, social media across Western Alaska lit up as residents posted photos and videos of open water where, normally, there's ice.

Three of the walruses had low to moderate levels of saxitoxin, while the fourth one had high levels.

No sea ice; hunters say it should not be like this today.
