An international team has drilled the longest ever sediment core from under an ice sheet, providing a record stretching back millions of years that will help climate scientists forecast the fate of the ice sheet in our warming world.

Global warming must peak below 2°C then return under 1.5°C as quickly as possible to limit the risk of dangerous “tipping points”, experts say.

Scientists say multiple Earth system components appear closer to destabilization than previously believed, putting the planet at increased risk of a “hothouse” trajectory driven by feedback loops that can amplify the consequences of global warming.

As Canada experiences record snowfall, new research from the University of Waterloo suggests that tiny amounts of industrial pollution trapped in snow can change how sunlight reaches the ground below and significantly alter fragile environments.

New research shows a single year of warmer-than-average Arctic temperatures can cause malnutrition in Arctic seals, intensifying risks to Inuit food security and northern ecosystems already under pressure from environmental toxins, warn Simon Fraser University researchers.

Alaska had one of its warmest years of the previous 100 in 2025, the Alaska Climate Research Center reports in its year-end summary.

The most high-risk conditions for fires are increasingly happening across countries at the same time, making resulting wildfires even more challenging to tackle, new research reveals.

How will a warming Arctic affect plant growth on Svalbard? Researchers encased plant plots in a thick layer of ice during the winter and used little greenhouses to heat up those plots in the summer.

Geologic reservoirs that trapped petroleum for millions of years are now being repurposed to store the greenhouse gas carbon dioxide.

New research from the University of Copenhagen suggests that volcanic eruptions during the Ice Age may have triggered sudden climate change by disrupting the Atlantic Meridional Overturning Circulation (AMOC), causing temperatures to fluctuate between hot and cold for thousands of years.
