Ariane 6 Launches Metop-SGA1 Weather Satellite into Polar Orbit
Europe’s heavy-lift Ariane 6 rocket completed its third successful launch on Aug. 12, 2025, lifting off from Kourou, French Guiana at 8:37 p.m. EDT. The mission carried Metop-SGA1, an 8,900-pound next-generation polar-orbiting weather satellite operated by EUMETSAT. Placed into an 800 km polar orbit 64 minutes after liftoff, Metop-SGA1 will deliv...

Greenland's Melting Glaciers Feed Ocean Life, Study Finds
A new NASA-led study reveals that Greenland’s melting glaciers are fueling life in the Arctic Ocean. Each summer, massive freshwater plumes from glaciers like Jakobshavn drag deep-sea nutrients upward, boosting phytoplankton growth by up to 40%. These microscopic organisms form the base of the marine food web and play a key role in carbon absorpt...

Greenland's Melting Ice Caps Reveal The True Extent Of Climate Change
In recent decades this territory 80 per cent of which is covered with ice has recorded a loss of frozen mass that outpaced previous estimates by 20 per cent.

Polar Bears in Alaska Face Rising Pathogen Threats Due to Climate Change
Polar bears in the Chukchi Sea are increasingly exposed to pathogens like Toxoplasma gondii, brucellosis, and canine distemper due to warming climates. Researchers revealed a significant rise in pathogen antibodies in polar bears since the 1990s, linking this trend to reduced sea ice, altered diets, and human interaction. The findings raise concern...

Rare Sea Smoke and Streaming Snow Phenomena Captured Near Pine Island Glacier
In October 2024, Pine Island Glacier displayed unusual atmospheric phenomena, including rare sea smoke and blowing snow. Captured by NASA's Landsat 8, these events were visible due to clear skies. Strong winds pushed warmer water to the surface, creating sea smoke, while blowing snow from the West Antarctic Ice Sheet influenced the glacier’s land...

The Day After Tomorrow Was Just A Warm-Up. Real Danger Looms, Warn Scientists
A new study has revealed that predicting the timing of catastrophic climate events, such as the collapse of the Atlantic Meridional Overturning Circulation (AMOC), is extremely difficult.

Polar Bears At Risk Of Starvation Due To Longer Ice-Free Arctic Periods
Polar bears in Canada's Hudson Bay risk starvation as climate change lengthens periods without Arctic Sea ice, despite the creatures' willingness to expand their diets.

Polar Bear Dies As Bird Flu Strain H5N1 Sweeps Across the Globe
In the last two years, as more wild birds got sick, different animals like dolphins, porpoises, seals, foxes, and otters also got the disease.

North Greenland's Ice Shelves Shrink By A Staggering 35% In 45 Years, Study Finds
The largest floating ice shelves in the polar ice sheet have lost more than a third of their volume since 1978.

Tides Are Eating Into Glaciers, Triggering More Melting, Study Finds
Melting glaciers could raise sea levels more than previously thought because of the way polar ice behaves where it meets the ocean floor.

Scientists Discover Unique Group of Polar Bears Relying on Glacial Ice in Southeast Greenland
Scientists have discovered a unique group of polar bears with distinct behaviour in southeast Greenland, that have remained isolated for hundreds of years. These polar bears are genetically different from other polar bears. While polar bears in the Arctic region usually depend on sea ice to hunt seals, the new group of polar bears appears to have ...

The Arctic Is 'Behaving So Bizarrely'
Last month, temperatures in the high Arctic spiked dramatically, some 36 degrees Fahrenheit above normal - a move that corresponded with record low levels of Arctic sea ice during a time of year when this ice is supposed to be expanding during the freezing polar night.

Polar Sea Ice The Size Of India Vanishes In Record Heat
Sea ice off Antarctica and in the Arctic is at record lows for this time of year after declining by twice the size of Alaska in a sign of rising global temperatures, climate scientists say.

Polar Sea Ice Extent Hit Record Low For November
Last month saw the lowest polar sea ice extent for November - the seventh month this year to have hit record low - as the Arctic and Antarctic lost vast swaths of ice due to higher-than-average temperatures, scientists say.

Polar Bear Numbers To Plunge A Third As Sea Ice Melts: Study
Polar bear numbers could drop a third by mid-century, according to the first systematic assessment, released Wednesday, of how dwindling Arctic sea ice affects the world's largest bear.
