Our planet's South Pole is arguably one of the most mysterious places there are. The exploration of the area is still in its infancy, and every new study brings to light remarkable finds, such as microbes living under miles of ice, at freezing temperatures, and with almost inexistent food sources. A deeper under... |

People living on an island of New Zealand were puzzled to discover one morning a large number of icebergs floating off their coasts. The ice blocks, more than a hundred of them, came all the way from Antarctica, according to a group of researchers, and it may be that they were set adrift more than 9 years ago. During... |

The American space agency NASA started measuring the extent of Arctic ices in 1979, via its satellite program. Since then, it has conducted constant investigations of the North Pole, and has drawn maps of ice extents during every minimum and maximum extent of the ice sheets. Measurements for this year indicate that t... |

There is no doubt in anyone's mind that we are currently in a warm Earth period. And we're not talking here about the climate change-type of warming, but of the planet's natural warming/cooling cycle. The current trend began some 11,700 years ago, and that is why Danish researchers looking into the his... |

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... |

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 ... |
