Russia’s War on Ukraine Chills Arctic Climate Science

CLIMATEWIRE | For much of his career, Alaska-based scientist Vladimir Romanovsky has collaborated with colleagues back home in his native Russia on one of the most important — and enigmatic — aspects of Earth’s climate system.They’ve been monitoring gradual shifts in Arctic permafrost, a type of carbon-rich frozen soil common in the chilliest parts of the world.But in the last two years, these collaborations have grown cold.On supporting science journalismIf you're enjoying this article, consider supporting our…

The Secret Jellyfish Dinners of the Arctic Depths

Credit: Alfred Wegener Institute / Charlotte HavermansFirst observation of marine invertebrates eating live and dead jellyfish during Arctic winter.In the dark and cold of the months-long polar night, food resources are limited. Some groups of marine organisms in the polar regions overcome this challenge by going into a metabolic resting state in winter, surviving on reserves accumulated during the short growth season. But others, such as several species of marine…

Getting to Devon Island in Canada’s Far North was so hard, it felt like traveling to the moon

I've been very fortunate as a documentary and adventure series filmmaker, having the opportunity to travel all over Canada and the world doing what I love. But my latest project sent me on a mission to a lunar landscape in Canada's Far North — one of the most difficult places I've ever had to reach. For the CBC Short Doc My New Moon Suit, we travelled to Devon Island, nestled in Canada's Arctic, to run our very own test of a new spacesuit. It's here, on the world's largest uninhabited island, that new-concept spacesuits…

What does a warming Arctic mean for the future?

Credit: Unsplash/CC0 Public Domain The Arctic is experiencing disproportionately higher temperature increases compared to the rest of the planet, triggering a series of cascading effects. This rapid warming has profound implications for global climate patterns, human populations and wildlife. The Copernicus Imaging Microwave Radiometer mission (CIMR) will provide measurements to decision…

Unlocking the Mystery of Arctic Wetlands’ Methane Emissions Surge

A research team from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) analyzed wetland…

Global Warming’s New Threat: Arctic Permafrost’s Carbon Bomb

Recent Dartmouth research underscores the significant influence of Arctic permafrost on the formation of northernmost rivers and highlights the risks of substantial carbon release due to climate change-induced thawing. By analyzing thousands of watersheds, the study reveals the unique characteristics of Arctic river valleys and stresses the importance of understanding these landscapes in the face of global warming. Credit: SciTechDaily.comAs the Arctic warms, the growth of rivers could release carbon emissions equivalent…

Frequent Arctic Ocean Heatwaves Set to Become the New Climate Reality

Recent studies reveal a significant increase in marine heatwaves in the Arctic Ocean, with temperatures rising above average and thinning ice leading to a new Arctic phase. Human-induced greenhouse gases are a major contributing factor, threatening the region’s ecosystem. Credit: SciTechDaily.comMarine heatwaves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions – as shown in a study just released by Dr. Armineh Barkhordarian from…

Airlander 10’s ‘flying bum’ set to jet eco-tourists to the Arctic

A voluptuous aircraft dubbed “The Flying Bum” has joined the fleet of Grands Espaces, a French eco-tourism company. Officially called the Airlander 10, the climate-conscious craft brings the Zeppelin era into the future. Built by the UK’s Hybrid Air Vehicles (HAV), the blimp used helium and electricity to stay aloft. In development since 2007, the Airlander 10 promises lower emissions, fuel burn, noise, and operating costs. HAV bills the vehicle as “the future of zero-carbon aviation.” With a…

Frequent marine heat waves in the Arctic Ocean will be the norm, says new study

The figure shows the most powerful heat wave in the Arctic Ocean to date in 2020, which continued for 103 days. The cumulative heat intensity sums up the daily anomalies in water temperature recorded over the duration of the heat wave in degrees Celsius. Credit: UHH/CLICCS/A. Barkhordarian Marine heat waves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas…

Permafrost alone holds back Arctic rivers—and a lot of carbon

Comparison between drainage densities and hydrogeomorphic configurations in permafrost and temperate landscapes of comparable relief and annual precipitation. Credit: Proceedings of the National Academy of Sciences (2024). DOI: 10.1073/pnas.2307072120 New research from Dartmouth College provides the first evidence that the Arctic's frozen soil is the dominant force shaping Earth's northernmost rivers. Permafrost, the thick…
