The aftermath of a historic 2020 heat wave could still be felt in Siberia a year later.

Arctic Ice Shelf Theory Challenged by Ancient Algae
Chemical signatures of marine organisms reveal that seasonal sea ice, not a massive ice shelf, persisted in the southern Arctic Ocean for 750,000 years.
Arctic Rivers Trade Inorganic Nitrogen for Organic
Climate change is shifting the makeup of a key nutrient in rivers across Russia, Alaska, and Canada, with the potential for ecosystem-wide impacts.
As the Arctic Warms, Soils Lose Key Nutrients
Climate change heats not only the air and the ocean but also the soil, where key processes that determine fertility and carbon sequestration operate in a fine-tuned balance.
New Research Shows More Extreme Global Warming Impacts Looming for the Northeast
One new study identifies a 17% increase in the destructive potential of the strongest nor’easters, while another bolsters links between Arctic ice melt and dangerous blizzards.
The Mid-20th Century Winter Cooling in the Eastern U.S. Explained
A new analysis of historical jet stream behavior reveals that increases in jet stream waviness accounted for 55-71% of winter cooling in the eastern United States from 1958 to 1988.
New Satellite Adds Evidence of an Earth-Shaking Wave
A tsunami struck a fjord in East Greenland in 2023, ringing seismometers for nine straight days. A new satellite study provides the first observational evidence of the waves.
Water Tracks: The Veins of Thawing Landscapes
Tracing and tracking change in permafrost flowpaths could reveal the dynamics of warming poles.
Finding Consensus on Arctic Ocean Climate History
Understanding the effects of a “blue” Arctic Ocean on future climate requires a coordinated effort to study Earth’s past warm periods using a variety of classical and cutting-edge methods.
Seaweed Surges May Alter Arctic Fjord Carbon Dynamics
Climate change–accelerated seaweed growth could cause seaweed-dependent microbes to proliferate and consume more oxygen, leading to a rise in oxygen-starved zones.
