African lions are under the same threats extinct sabre-toothed tigers faced.

A warming climate could affect the stability of alpine grasslands in Asia's Tibetan Plateau, threatening the ability of farmers and herders to maintain the animals that are key to their existence, and potentially upsetting the ecology of an area in which important regional river systems originate, says a new study.

Scientists have now discovered an active hydrological system of water conduits and sediment ridges below the Antarctic ice sheet.

One of the robust features of global warming under increasing greenhouse gas concentrations is that different places warm at different paces. It turns out that the fast warming in each region has its own cause. Ocean heat transport links subpolar and Arctic warming, but that is not the whole story.

Scientists have known for over a decade that the West Antarctic Ice Sheet has been losing mass and contributing to sea level rise.

Central parts of Antarctica's ice sheet have been stable for millions of years, from a time when conditions were considerably warmer than now, research suggests.

A commitment to reducing global emissions of short-lived climate pollutants (SLCPs) such as methane and black carbon could slow global warming while boosting public health and agricultural yields, aligning the Paris Climate Agreement with global sustainable development goals, a new analysis by an international panel of scientists shows.

The amount of dissolved oxygen contained in the water -- an important measure of ocean health -- has been declining for more than 20 years, reveals a new analysis of decades of data on oceans across the globe.

A tiny shark tooth, part of a mantis shrimp and other microscopic marine organisms reveal that as the Andes mountains rose, the Eastern Amazon sank twice, each time for less than a million years.

Climate plays a key role in determining what animals can live where. And while human-induced climate change has been causing major problems for wildlife as of late, changes in the Earth's climate have impacted evolution for millions of years -- offering tantalizing clues into how to protect animals facing climate change today. In a new paper, scientists have delved into the effects of Ice Age climate change upon the evolution of tiny, hand-standing skunks.

A new analysis of an ice core from Dome Fuji in Antarctica, along with climate simulation results, shows a high degree of climate instability (that is, rapid climate fluctuations) within glacial periods with intermediate temperatures. This instability was attributed primarily to global cooling caused by a reduced greenhouse effect.

The rift in the Larsen C ice shelf in Antarctica now has a second branch, which is moving in the direction of the ice front, researchers revealed after studying the latest satellite data. The main rift in Larsen C, which is likely to lead to one of the largest icebergs ever recorded, is currently 180 km long. The new branch of the rift is 15 km long.

Glacier flow at the southern Antarctic Peninsula has increased since the 1990s, but a new study has found the change to be only a third of what was recently reported.

Parts of the ice of the Juvfonne snow patch in Jotunheimen are 7600 years old, which makes it the oldest dated ice on mainland Norway.

Ice cores drilled from a glacier in a cave in Transylvania offer new evidence of how Europe's winter weather and climate patterns fluctuated during the last 10,000 years, known as the Holocene period.

After an unusually intense heat wave, downpour or drought, climate scientists inevitably receive phone calls and emails asking whether human-caused climate change played a role.

A century-old mystery involving a famous red waterfall in Antarctica has now been solved by researchers. New evidence links Blood Falls to a large source of salty water that may have been trapped under Taylor Glacier for more than 1 million years.

Scientists have created the most comprehensive and high-resolution atlas of the seafloor of both Polar Regions.

New research describes for the first time the role that warm, dry winds play in influencing the behavior of Antarctic ice shelves.

Microplastics, which are particles measuring less than 5 mm, are of increasing concern. They not only become more relevant as other plastic marine litter breaks down into tiny particles, they also interact with species in a range of marine habitats. A new study takes a look at how global climate change and the impact of changing ocean circulation affects the distribution of marine microplastic litter.
