Bern’s ice core researchers were already able to demonstrate in 2008 how the concentration of CO2 in the atmosphere has changed over the past 800,000 years. Now, using the same ice core from the Antarctic, the group led by Bernese climate...

Ann Arbor (Informed Comment) – A new article in Geophysical Research Letters found that four times as much of the Antarctic ices shelves would melt under a scenario where we heat the earth by 7.2 degrees F. (4 degrees C.) as opposed to...
The melting rate of the Antarctic ice sheet is mainly controlled by the increase of ocean temperatures surrounding Antarctica. Using a new, higher-resolution climate model simulation, scientists from Utrecht University found a much slower ocean...

During 1992–2016, the AIS changed from a positive mass balance of over 100 Gt a−1, which was reducing sea-level rise by 0.3 mm a−1, to a state of balance close to zero by 2014. The mass balance successively changed from a gain of 144 ± 61 Gt...

A video shows shows a fire erupting on a vessel in the Antarctic Ocean.
It left the ship with a damaged engine and only able to move at slower speeds.
No injuries were reported, and...

He added: "The possibility of Pine Island Glacier entering an unstable retreat has been raised before but this is the first time that this possibility is rigorously established and quantified.
A research team of international space scientists has found new evidence of a low-altitude meteoritic touchdown event reaching the Antarctic ice sheet 430,000 years ago.

Understanding the evolution of the polar sea ice is not enough to study the effects of the climate change on marine ecosystems in Antarctic seafloors. It is also necessary to determine the intensity of phytoplankton local production during the...

An analysis of historic and projected simulations from 19 global climate models shows that, because of climate change, the temperature in the Antarctic peninsula will increase by 0.5 to 1.5 degrees Celsius by 2044.
On December 6, 2016, a high-energy particle hurtled to Earth from outer space at close to the speed of light. It triggered the sensors of the IceCube Neutrino Observatory, a massive telescope buried in the Antarctic glacier. IceCube had seen a...
