2025 Was One Of Three Hottest Years On Record: Scientists
Temperatures remained high despite the presence of a La Nina, the occasional natural cooling of Pacific Ocean waters that influences weather worldwide. Researchers cited the continued burning of fossil fuels that send greenhouse gases into atmosphere

New Study Shows Antarctic Waters Unleashed Ancient Carbon at the Ice Age’s End
New research shows that shifting Antarctic circulation after the last Ice Age released ancient deep-ocean carbon into the atmosphere. Using Southern Ocean sediment cores, scientists traced how expanding Antarctic Bottom Water mixed long-isolated, carbon-rich waters upward. The findings reveal a major but underappreciated driver of early Holocene wa...

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...

SpaceX Sends Sentinel-6B to Orbit for Precision Sea-Level Tracking
SpaceX successfully launched the Sentinel-6B ocean-monitoring satellite on November 17, 2025, marking its 500th orbital mission using a reused Falcon 9 booster. Sentinel-6B will extend more than 40 years of continuous sea-level measurement, delivering high-precision global ocean data as part of Europe’s Copernicus climate program. Equipped with a...

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...

How Climate Change And Warming Oceans Led To Kolkata's Historic Downpour
As Kolkata begins to mop up after one of its worst deluges in recent memory, scientists warn that such extreme weather events are no longer anomalies - they are becoming the new normal.

2025 Witnessed World's Third-Hottest August On Record
Devastating wildfires and blistering heatwaves during the world's third-hottest August on record underscored the urgency of tackling climate change and preparing for its deadly consequences, the European global warming monitor said Tuesday.

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.

Atlantic Hurricane Season Sets Peak Record As Storm Erin Threatens US Coast
Hurricane Erin's massive footprint battered Caribbean islands with heavy gusts and downpours on Monday, as it threatened rip currents and flooding along the US East Coast later this week, even without a predicted landfall.

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...

Explained: Why India's Monsoons Are Now Deadlier And More Unpredictable
Monsoon rainfall is becoming more erratic, with intense downpours followed by dry spells. This variability affects agriculture, water systems, and disaster preparedness.

From Ice Sheets To Oceans: The Climate Tipping Points That Worry Scientists
A climate tipping point is a critical threshold where a small environmental change can lead to dramatic and often irreversible shifts.

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.

Warm Seas Fuel Dangerous 'Weather Bomb' Set To Hit New South Wales Coast
Right now, a severe storm likely to be the first significant east coast low in three years is developing off the coast of New South Wales.

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.
