Between recent ice ages, temperatures in Antarctica apparently increased significantly, a new body of researches shows. This has led scientists to conclude that the Eastern part of the Southern continent, which is currently melting faster due to global warming, also did so in the past. This demonstrates an ongoing su... |

A new survey conducted by the American space agency's Ice, Cloud, and land Elevation Satellite (ICEsat) has revealed that more and more ice is falling off the Greenland and Antarctic sheets into the world's oceans, as glaciers get thinner on account of global warming. The formations increase their flow rate... |

Lake Vida is, arguably, one of the most peculiar places on the planet, and also one of the places where you don't expect to find any life whatsoever. Located some 60 feet under the ice sheet in Southern Antarctica, the lake is, in fact, an ice bottle of brine, a geological curiosity, experts say. However, when t... |

In the first large-scale study to ever prove so, experts at the Cardiff University, in the United Kingdom, determined that the decline in CO2 levels in the planet's atmosphere some 34 million years ago led to the formation of the ice caps in Antarctica. Scientists from the University of Bristol and the Texas A&M... |

The Southern Hemisphere is known for the fact that it offers a more advantageous position for observing the Universe. Stars, galaxies, black holes, pulsars, and everything else in between can be seen more clearly from these regions. In fact, a team of experts from the United States and Australia has announced that it... |

As years of satellite observations in the Antarctic went by, NASA experts observed that the southern continent had, in fact, a very well developed “plumbing system” underneath its miles of ice. Underground lakes, pressured by the tons of ice above, have created thin water layers between the rocks and the ... |

Living in some of the most secluded places in the world, such as Australia's Antarctic bases, can be a very challenging task, especially if you take into account the fact that most of these facilities remain isolated from the rest of the world for more than nine months per year.

According to a recent scientific study, the collapse of the West Antarctic Ice Sheet (WAIS) would only raise sea levels by half of the originally estimated amount. Rather than forcing waters worldwide up by five to six meters (15 to 20 feet), a catastrophic meltdown will only generate a 3.3-meter (11-foot) lift, a Br... |

For quite some time now, climatologists have known that the layers found in most ancient ice shelves and in large icebergs can be used to get a glimpse into our planet's ancient history, at least as far as climate changes go. Each layer is specific to a certain period of time in our planet's past, and each ... |

Most glaciers in the Antarctic don't lie on solid rock, as many believe. Instead, they virtually float on top of underground glacial lakes, which are more like fluid ice streams. They act as a lubricant layer between the rock bed and the glaciers on top, thus allowing gigatonnes of ice to move towards the ocean.... |
