Glaciers Speed Up in Summer and Slow in Winter, New Global Map Reveals
A new global map of glacier speeds, built from nearly a decade of satellite observations, shows that glaciers consistently move faster in summer and slower in winter. Meltwater acts as a natural lubricant, accelerating flow during warm months. Scientists warn that glaciers with strong seasonal shifts are likely to speed up long-term, adding to futu...

Scientists Warn Southern Ocean Could ‘Burp’ Stored Heat, Delaying Global Cooling for 100 Years
New modelling suggests the Southern Ocean could one day release the vast heat it has stored from greenhouse gas pollution. If CO₂ levels were pushed to net-negative, deep convection may trigger a sudden “thermal burp” that warms the planet for decades. Though idealised, the study shows how Antarctica’s surrounding seas could shape long-term...

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...

Atmospheric Carbon Dioxide Soars to 424PPM, Marking Biggest Yearly Jump Ever
The WMO reports Earth’s atmospheric CO₂ reached 422.8 ppm in 2024 — the biggest annual rise ever recorded. Driven by fossil-fuel emissions, wildfires, and weakening carbon sinks, the surge intensifies global warming. Scientists warn that delayed emission cuts could entrench irreversible changes in weather, ecosystems, and sea levels.

Over 100 Million Buildings Worldwide Could Face Flooding Risk From Rising Seas, Study Warns
A McGill-led study warns that rising sea levels could endanger more than 100 million buildings across the Global South, with coastal infrastructure in Africa, Southeast Asia, and the Americas most at risk. The findings highlight the urgent need for emissions cuts and coastal adaptation.

Antarctica Sees Similar Climate Change Effects As Greenland: Study
The planet's warming climate is having effects in Antarctica that increasingly resemble those observed in the Arctic, meaning global sea levels could rise faster that previously predicted, Danish researchers warned.

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.

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.

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.

Will Surging Sea Levels Kill The Great Barrier Reef? Here's What Might Help
In the 20th century, global sea level rose faster than at any other time in the past 3,000 years. Its expected to rise even further by 2100, as human-induced climate change intensifies.

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.

How Melting Glaciers Threaten Biodiversity, Lives And Water Resources
Glacial melting can result in nuclear power plant shutdowns, agriculture and water resources being put at risk, and coastal cities being threatened by flooding.

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.
