Sea ice thickness is inferred by […]

The relationships among CAW, heatwaves, wildfires, and pollution. Anomalous anticyclones characterize the atmospheric circulation that develops concomitantly over the three remote regions around the summertime Arctic (July and August). The authors named it the circum-Arctic wave (CAW) pattern. These anticyclones induce warm and dry conditions from the surface to the […]

It may not be very well known, but the Arctic Ocean leaks enormous amounts of the potent greenhouse gas methane. These leaks have been ongoing for […]

1979 – 2019 Throughout 2020, the Arctic Ocean and surrounding seas endured several notable weather and climate events. In spring, a persistent heatwave over Siberiaprovoked the rapid melting of sea ice in the East Siberian and Laptev Seas. By the end of summer, Arctic Ocean ice cover melted back to the second-lowest […]

ANIMATION For animals in the Arctic, life is a balancing act. Seasonal cues, such as warmer spring temperatures or cooler temperatures in the fall, tell animals when to migrate, when to mate, and when and where to find food. Predators and prey, birds and mammals alike follow this natural schedule, […]

Aleutian Islands are an archipelago comprising dozens of islands with 40 active and 17 dormant volcanoes. A researcher from MIPT has proposed a new explanation for the Arctic’s rapid warming. In his recent paper in Geosciences, he suggests that the warming could have been triggered by a series of great earthquakes. […]

Water from Canada’s Mackenzie River enters the blue Arctic Ocean in July 2012. White areas in the top half of the photo are largely sea ice, while those below are clouds over land. Credit: NASA Earth Observatory A new study shows that increased heat from Arctic rivers is melting sea […]
