A new study suggests the world’s oxygen depleted seas may have a chance of returning to higher oxygen concentrations in the centuries to come, despite our increasingly warming climate.

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

Colorado’s warm and dry winters have tipped the balance in a long-running ecological tug-of-war.

Some tropical land regions may warm more dramatically than previously predicted, as climate change progresses, according to a new CU Boulder study that looks millions of years into Earth’s past.

Researchers at Concordia have developed a new method of measuring the amount of usable water stored in snowpacks.

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.

To reduce air pollution associated with ocean transport, the International Maritime Organization tightened restrictions on sulfur content in ship fuel, resulting in an 80% reduction in emissions by 2020.

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.

A new analysis of air quality data from the past 70 years shows that Canada’s record wildfire smoke in 2023 is part of a broader, continent-wide trend toward smokier skies across North America.

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.
