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.

Why Mars Dried Up: Scientists Uncover The 'Missing Link' To Its Lost Oceans
A regional dust storm on Mars may have played a significant role in the planet's water loss, pushing water vapor high into the atmosphere.

Scientists Plan To Build 150-Meter Wall To Mitigate "Doomsday Glacier" Melting Crisis
Experts have acknowledged significant technical challenges, including the wall's survival in extreme Antarctic conditions and long-term ocean exposure.

Sinking Calcium Carbonate Locked Away Greenhouse Gases, Reveals New Study
Scientists have solved a 66-million-year climate mystery, explaining how Earth cooled from a tropical greenhouse to an ice-capped world. New research reveals ocean calcium levels dropped by more than half, reshaping marine chemistry. As calcium declined, oceans locked away more carbon dioxide, lowering atmospheric CO2. The study links deep-Earth pr...

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.
