An Antarctic field campaign last winter led by the US and Australia has successfully extracted some of the largest samples of air dating from the 1870s until today. Researchers will use the samples to look for changes in the molecules that scrub the atmosphere of methane and other gases.

Canada's northernmost islands, Ellesmere and Axel Heiberg islands in Nunavut, were home to a vibrant, temperate forest 56 million years ago, according to fossil research.

Glaciologists have unveiled the most accurate portrait yet of the contours of the land beneath Antarctica's ice sheet -- and, by doing so, have helped identify which regions of the continent are going to be most vulnerable to the impact of future climate warming.

Findings on ice retreat across the global tropics clarifies how the low latitudes transformed during the end of the last ice age and can help current-day predictions of our own climate future.

A new study says Glacier National Park's iconic mountain goats are in dire need of 'air conditioning.'

Chemistry researchers have uncovered a better way to scrub carbon dioxide from smokestack emissions, which could be a key to mitigating global climate change.

Satellite data has given scientists clues about how, when and why Greenland's glaciers are shrinking -- and shows a sharp increase in glacial retreat beginning about 2000, according to new research.

As the climate changes, myriad animal populations are being impacted. In particular, Arctic sea-ice is in decline, causing polar bears in the Barents Sea region to alter their feeding and hunting habits. Bears that follow sea-ice to offshore areas have higher pollutant levels than those staying on land -- but why? A new study reports the likely reasons.

New time-lapse videos of Earth's glaciers and ice sheets as seen from space -- some spanning nearly 50 years -- are providing scientists with new insights into how the planet's frozen regions are changing.

Greenland is losing ice seven times faster than in the 1990s and is tracking the Intergovernmental Panel on Climate Change's high-end climate warming scenario, which would see 40 million more people exposed to coastal flooding by 2100.

The Arctic region is heating up faster than any other place on Earth, and as more and more sea ice is lost every year, we are already feeling the impacts. Researchers explored strategies for cooling down the oceans in a world without this important cooling mechanism.

The last remaining tropical glaciers between the Himalayas and the Andes will disappear in the next decade -- and possibly sooner -- due to climate change, a new study has found. The glaciers in Papua, Indonesia, are ''the canaries in the coal mine'' for other mountaintop glaciers around the world, said one of the researchers.

Satellite data from the European Space Agency (ESA) has now been used as the basis for new insights on the deep structure of the continent Antarctica.

Researchers have identified forests in the western United States that should be preserved for their potential to mitigate climate change through carbon sequestration, as well as to enhance biodiversity.

According to a much-debated geo-engineering approach, both sea-ice retreat and global warming could be slowed by using millions of wind-powered pumps, drifting in the sea ice, to promote ice formation during the Arctic winter.

Researchers used 120,000-year-old fossils to predict how Gulf of Mexico coral reefs will respond to climate change toward the end of this century.

With 2019 on pace as one of the warmest years on record, a major new study reveals how rapidly the Arctic is warming and examines global consequences of continued polar warming. The study reports that the Arctic has warmed by 0.75 degrees C in the last decade alone.

The ancient Romans relied on long-distance timber trading to construct their empire, according to a new study.

Each hair-thin glass fiber in a buried fiber optic cable contains tiny internal flaws -- and that's a good thing for scientists looking for new ways to collect seismic data in places from a busy urban downtown to a remote glacier.

A survey of coral reef cores on the Great Barrier Reef has revealed how it has responded to recent periods of rapid sea-level rise. The study, covering the past 9000 years, has revealed a system in delicate balance.
