After all, it has no indigenous inhabitants; only penguins, seals and albatrosses living far away from the dangers faced by wildlife on other continents. Similarly, to political experts, Antarctica is in good hands, governed as it is by the widely celebrated Antarctic Treaty System (ATS), which is considered one of the most successful international legal regimes.

Geosciences Column: A new rock outcrop map and area estimation for the entire Antarctic continent. Antarctica has been known as “the frozen continent” for almost as long as we have known of its existence.
It may be the only place on Earth where, instead of information on the extent of glaciers or ice caps, there exists a dataset of all non-icy areas compiled from satellite imagery. However, this repository is far from perfect: while satellite resolution and coverage have been steadily improving, Antarctica is challenging ground for remote sensing. Ice and cloud cover can be difficult to tell apart, and the low position of the sun in the sky means that long shadows can make snow, ice and rock very difficult to distinguish. 1KM below freezing - @lewispugh swims in 0° C waters to raise awareness about protecting Antarctica's seas. #Antarctica2020 #CleanSeas.

This frozen continent at the bottom of our planet has the potential to either become one of the most fiercely contested zones in the world, or the most collaborative. Antarctica is one of four internationally recognised global commons along with the atmosphere, the high seas and outer space. These are all areas that have historically been guided by the principle of the common heritage of humankind. The continent is governed by the Antarctic Treaty System, a complex set of arrangements developed to regulate relations between states with interests and territorial claims in the region. Antarctic quest to find 'oldest ice' Image copyright BAS/R.Mulvaney Scientists set out this week to try to find the oldest ice in Antarctica.
They are seeking a location where they can drill a frozen core that contains a continuous record of climate change stretching back 1.5 million years. The chemistry of this ice can be used to deduce past temperatures on Earth. And tiny bubbles of air trapped inside the core will also betray the levels of heat-trapping gases such as carbon dioxide that were once present in the atmosphere. This new data is expected to provide additional confidence in the modelled forecasts of how conditions on the planet might develop in the future. Antarctica, the confusing continent.
How much longer can Antarctica’s hostile ocean delay global warming? Colin Monteath/Minden/NGC Strong winds help to pull up ancient water from the ocean bottom.
Joellen Russell wasn’t prepared for the 10-metre waves that pounded her research vessel during an expedition south of New Zealand. “It felt like the ship would be crushed each time we rolled into a mountain of water,” recalls Russell, an ocean modeller at the University of Arizona in Tucson. At one point, she was nearly carried overboard by a rogue wave. But what really startled her was the stream of data from sensors analysing the seawater.

For decades Antarctica - the only continent with no indigenous population - hosted only the simplest huts as human shelters. But, as Matthew Teller finds out, architecture in the coldest, driest, windiest reaches of our planet is getting snazzier. Today in Ladybird 17 Jan 1912 Scott, Wilson, Oates, Bowers & Edgar Evans reach South Pole, in the knowledge that Amundsen had arrived 1st. The huge crack in this Antarctic ice shelf just grew by another 6 miles. A Nov. 10 photo made available by NASA shows a view of a massive rift in the Antarctic Peninsula’s Larsen C ice shelf, Antarctica.
(John Sonntag/NASA via European Pressphoto Agency) A crack more than 100 miles long in one of Antarctica’s largest ice shelves grew another 6 miles in a little more than two weeks this month, British scientists reported Thursday. That’s on top of an 11-mile growth that occurred in the second two weeks of December — representing a 17-mile total advance in not much more than a month. The extension of the rift in the Larsen C ice shelf ran roughly parallel to the ocean-terminating front of the floating ice shelf, and so, did not bring it any closer to breaking off a large piece — 12 miles of ice still connect the emerging ice island to the larger shelf. But the parallel growth may ensure that the iceberg, when it does break off, will be somewhat larger. Giant iceberg poised to break off from Antarctic shelf.
A giant iceberg, with an area equivalent to Trinidad and Tobago, is poised to break off from the Antarctic shelf.
A thread of just 20km of ice is now preventing the 5,000 sq km mass from floating away, following the sudden expansion last month of a rift that has been steadily growing for more than a decade. The iceberg, which is positioned on the most northern major ice shelf in Antarctica, known as Larsen C, is predicted to be one of the largest 10 break-offs ever recorded. Professor Adrian Luckman, a scientist at Swansea University and leader of the UK’s Midas project, said in a statement: “After a few months of steady, incremental advance since the last event, the rift grew suddenly by a further 18km during the second half of December 2016. Only a final 20km of ice now connects an iceberg one quarter the size of Wales to its parent ice shelf.”
“If it doesn’t go in the next few months, I’ll be amazed,” Luckman told BBC News. Discovering Antarctica - interactive education for schools.
