Global Antarctic Research Declines Amid Growing Climate Crisis
Ice loss in Antarctica and its impact on the planet - sea level rise, changes to ocean currents and disturbance of wildlife and food webs - has been in the news a lot lately.

What Ancient Ice Sheets Can Tell Us About Future Sea Level Rise
When visiting Godrevy beach on the north Cornish coast, most people look out to sea at the lighthouse, surfers and seals rather than the cliffs behind.

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.

NASA Reports 'Higher Than Expected' Sea Level Rise In 2024
NASA reports a higher-than-expected sea level rise in 2024, primarily due to thermal expansion of seawater, highlighting the urgent need to reduce greenhouse gas emissions to mitigate the devastating impacts of climate change.

Arctic Sea Ice Hits Lowest Peak In 47-Year Satellite Record: US Agency
This year's Arctic sea ice peak is the lowest in the 47-year satellite record, the US National Snow and Ice Data Center (NSIDC) said Thursday.

Greenland’s Melting Glaciers Expose 1,620 km of New Coastline Since 2000
Over the past 20 years, Greenland’s glaciers have melted enough to expose 1,620 kilometres of new coastline, altering the Arctic’s geography. Satellite data from 2000 to 2020 tracked these changes, showing significant ice loss. The study also identified 35 newly exposed islands, some of which remain unclaimed on existing maps. Scientists warn o...

As Glaciers Melt, Risk Of Catastrophic Flash Floods Rises For Millions
In mountain ranges around the world, glaciers are melting as global temperatures rise. Europe's Alps and Pyrenees lost 40% of their glacier volume from 2000 to 2023.

Record High Temperatures In 2024 Caused Ice Loss, Rise In Sea Levels: UN
The report said other factors could also have driven global temperature rises last year, including changes in the solar cycle, a massive volcanic eruption and a decrease in cooling aerosols.

Antarctic Ice Melt Weakens Strongest Ocean Current, Disrupting Global Circulation
The Antarctic Circumpolar Current, the planet’s most powerful ocean circulation system, could slow by 20 percent by 2050 due to melting Antarctic ice. Researchers suggest that the influx of fresh, cold water is disrupting convection, altering global ocean density. A weaker current may allow warm water to reach Antarctica, accelerating ice loss an...

Global Sea Ice Cover At Record Low In February Amid Persistent Hot Streak
In February, temperatures spiked up to 11 degrees Celsius above average near the North Pole as the world continued its persistent heat streak, said Europe's climate monitor.
-
Greenland's Ice Sheet Approaches Dangerous Tipping Point Amid Rapid Melting
Greenland’s massive ice sheet is losing ice at an accelerating rate, with scientists warning that a global temperature rise of just 2°C could trigger irreversible collapse. The loss of 230 gigatons of ice per year is the estimated threshold for this tipping point. If melting continues at current rates, sea levels could rise by approximately 7 me...

Massive Ice Age Landforms Found Under North Sea Provide Key Insights into Ancient Glaciers
Scientists have uncovered massive ice age landforms buried deep beneath the North Sea, revealing patterns of a colossal ice sheet that existed 1 million years ago. Using high-resolution sound wave imaging, researchers discovered features indicating a single, large ice sheet that shaped the region’s landscape. These findings provide new perspectiv...

Arctic Could Witness First Ice-Free Day In 3 Years, Study Reveals
Arctic sea ice has been melting at an unprecedented rate of more than 12 per cent each decade, according to NASA.

Arctic Ocean Likely to Experience Ice-Free Day by 2027, Study Warns
A study published in Nature Communications predicts the Arctic Ocean could face its first ice-free day as early as 2027, marking a critical environmental milestone. Conducted using 11 climate models and 366 simulations, the research highlights the urgent need for emission reductions. The loss of sea ice in the Arctic exacerbates global warming thro...

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...
