Scientists are looking for life in an area of Antarctica that is thought to be the place on Earth that most closely resembles the permafrost found in the northern polar region of Mars, at the Phoenix landing site. The scientists failed to find any active microbes, suggesting it will be unlikely and difficult to detect similar activity on Mars.

Around 720-640 million years ago, much of the Earth's surface was covered in ice during a glaciation that lasted millions of years. Explosive underwater volcanoes were a major feature of this 'Snowball Earth,' according to new research.

Climate change increases the danger of falling rocks in the Alps and other mountain regions, adding to existing risks for mountain climbers.

A new study measured a melt rate that is 25 times higher than expected on one part of the Ross Ice Shelf. The study suggests that high, localized melt rates such as this one on Antarctica's largest and most stable ice shelf are normal and keep Antarctica's ice sheets in balance.

Soil frost is a nearly universal process in the Arctic. In a recent dissertation, it is shown that the frequency and extent of soil frost is important for the release of the greenhouse gas carbon dioxide from arctic soil.

New research on West Antarctic seabed life reveals that the remote region of the South Orkney Islands is a carbon sink hotspot. The findings suggest that this recently designated (and world's first) entirely high seas marine protected area may be a powerful natural ally in combating rising carbon dioxide as sea ice melts.

Humanity has become a geological force that is able to suppress the beginning of the next ice age, a study shows. Cracking the code of glacial inception, scientists have found the relation of insolation and carbon dioxide concentration in the atmosphere to be the key criterion to explain the last eight glacial cycles in Earth history.

Ice sheets may be containing vast reservoirs of methane, adding a new concern regarding rapid ice sheet retreat, report scientists. This is the first comprehensive study that shows that there is a third process that can create, contain and maintain large amounts of gas hydrates: ice sheets.

The world's largest canyon may lie under the Antarctic ice sheet, according to analysis of satellite data by a team of scientists.

New research indicates an ongoing loss of ice on Niwot Ridge and the adjacent Green Lakes Valley in the high mountains west of Boulder is likely to progress as the climate continues to warm.
