UN Confirms 2015-2025 As Hottest Decade On Record
An increase in the concentrations of greenhouse gases "to their highest level in at least 800,000 years" has "upset this equilibrium," says the WMO.

Final Chapter Of A23a? Colossal Antarctic Iceberg Nears Its End, Might Disappear Within Weeks
Disintegration of the world's oldest iceberg has implications for global sea levels and marine ecosystems.

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.

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...
