Record-Breaking Drill Beneath Antarctic Ice Reveals Ancient Open Ocean and Future Sea Level Risks
Scientists drilled deeper than ever beneath the West Antarctic Ice Sheet and found sediment and marine remains showing the area was once open ocean. The 23-million-year record offers key clues about past melting, helping researchers better predict how quickly the ice sheet could retreat and affect future global sea levels.

Antarctica Nears Irreversible Climate Tipping Point, Scientists Warn
Antarctica is approaching irreversible climate thresholds, scientists warn. Rapid melting of the West Antarctic Ice Sheet, record-low sea ice, and collapsing ocean systems could raise global sea levels by over 3 m. These interconnected changes threaten coastal cities and ecosystems, urging immediate emission cuts to prevent cascading global consequ...

Sea Ice To Ocean Currents, Antarctica Is Undergoing Abrupt Changes
Melting sea ice allows oceans to warm more rapidly, which melts more sea ice. Once triggered, they can be difficult or even impossible to reverse on timescales meaningful to humans.

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...

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.

Our Oceans Are In Trouble: Here's How To Take Action Beyond The Outrage
Our oceans are in trouble. Catches from many of the world's fisheries are declining, with some fishing practices destroying enormous areas of the sea bed.

Southwest Pacific Hit By Unprecedented Marine Heat Waves In 2024: United Nations
Unprecedented heat waves in the Southwest Pacific affected more than 10% of the global ocean surface in 2024, damaging coral reefs and putting the region's last remaining tropical glacier at risk of extinction, the UN's weather body said on Thursday.

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.

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...
