How a shifting plate boundary and hot mantle material formed one of the largest canyons in the ocean.

In the longest-running field warming experiment of its kind, researchers have documented dramatic shifts in high-elevation mountain meadows, revealing that changes in climate alter not only the plants we can see above ground, but the invisible world of fungi and microbes in the soil below.

Antarctica’s pale expanses of ice keep water locked up and reflect heat from the planet — but the climate crisis is putting these safeguards at increasing risk.

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.
