Parts of ancient Antarctica were as warm as today's California coast, and polar regions of the southern Pacific Ocean registered 21st-century Florida heat, according to scientists using a new way to measure past temperatures.
The ozone hole that forms each year in the stratosphere over Antarctica was slightly smaller in 2013 than average in recent decades, according to NASA satellite data.
Scientists have discovered huge ice channels beneath a floating ice shelf in Antarctica. At 250 metres high, the channels are almost as tall as the Eiffel tower and stretch hundreds of kilometres along the ice shelf. The channels are likely to influence the stability of the ice shelf and their discovery will help researchers understand how the ice will respond to changing environmental conditions.
Evidence of diverse life forms dating back nearly a hundred thousand years has been found in subglacial lake sediments by a group of British scientists. The possibility that extreme life forms might exist in the cold and dark lakes hidden kilometres beneath the Antarctic ice sheet has fascinated scientists for decades.
Ocean waters melting the undersides of Antarctic ice shelves are responsible for most of the continent's ice shelf mass loss, a new study by NASA and university researchers has found.
University of Maryland School of Medicine researchers say they've established certain key features in proteins that are needed for life to function on Mars and other extreme environments.
If you need help in snow and ice, who better to ask for help than a yeti?
An American research team has successfully drilled through 2,600 feet of Antarctic ice to reach a subglacial lake and collect water and sediment samples that have been isolated for thousands of years.
The ambitious attempt to drill through two miles of ice to reach an Antarctic lake has been called off, following problems with the boiler used to heat water for drilling.
In support of their views, climate change skeptics have long pointed to the fact that Antarctic sea ice - unlike that in the Arctic - is actually growing.
The hole in the ozone layer over the Antarctic was the second smallest in the last two decades, data from NASA and the National Oceanic and Atmospheric Administration (NOAA) satellites shows.
A massive reservoir of the greenhouse gas methane could be lying hidden beneath the Antarctic Ice Sheet, in a ticking time bomb for climate change.
Scientists have discovered a valley a mile deep, hidden beneath the ice in West Antarctica.
If global temperatures continue to rise, Emperor penguins may eventually disappear from their East Antarctic home, according to a new study by Woods Hole Oceanographic Institution (WHOI) researchers.
The loss of Antarctic ice is caused mainly by warm ocean currents attacking the underside of ice shelves, a new NASA study has revealed.
Scientists have been able to count the number of emperor penguins in Antarctica by using satellite mapping technology - and there's twice as many as previously thought, they say.
Russian scientists have successfully drilled through approximately 2.5 miles of ice to reach the surface of an ancient sub-glacial Antarctic lake.
A team of four British engineers has completed the first stage of an ambitious project to explore an Antarcic lake.
Several previously-unknown species have been discovered on the seafloor near Antarctica, clustered around hydrothermal vents.
The appearance of the Antarctic ice sheets was triggered by a massive fall in the amount of atmospheric carbon dioxide, new research has found.
