A new analysis shows that the Pacific Northwest’s mature and old-growth forests are most at risk of severe wildfire in areas that historically burned frequently at lower severity.

A growing proportion of the UK’s energy infrastructure is located at sea, in the form of oil and gas platforms and offshore wind farms along with the connecting cables and pipelines.

Wetlands make up only about six percent of the land area but contain about 30 percent of the terrestrial organic carbon pool.

For decades, scientists knew there was a huge swath of undetected and unaccounted for per- and polyfluoroalkyl substances (PFAS) in the atmosphere, often referred to as PFAS dark matter, but no one knew how much was missing or how to measure them.

In parts of the Arctic, polar bears are in decline as sea ice, which they depend on to hunt, disappears. That is not the case, however, on the Norwegian island of Svalbard, where bears have actually managed to grow more plump even as ice melts away.

Trees play a central role in life on Earth. They store CO₂, provide habitats for animals, fungi, and insects, stabilize soils, regulate water cycles, and supply resources that humans rely on – from timber and food to recreation and shade on a hot day.

Large-scale melting of the Greenland Ice Sheet is irreversible and happening at a rapid rate, and now a new international study is the first to understand why.

Microbes across Earth’s coldest regions are becoming more active as glaciers, permafrost and sea ice thaw, accelerating carbon release and potentially amplifying climate change, according to a new international review from McGill University.

Even as global warming causes sea levels to rise worldwide, sea levels around Greenland will likely drop, according to a new paper in Nature Communications.

A new study shows that interactions between wolves and cougars in Yellowstone National Park are driven by wolves stealing prey killed by cougars and that shifts in cougar diets to smaller prey help them avoid wolf encounters.
