Antarctic


The ice shelf that holds Antarctica’s massive Pine Island Glacier from collapsing into the Southern Ocean is breaking up faster than before as climate change weakens the natural barriers to glacial melting, a new study finds. The research raises alarms over the potential for further accelerated sea level rise. The Pine Island Glacier holds about 160 trillion …

A critical Antarctic glacier is looking more vulnerable as satellite images show the ice shelf that blocks it from collapsing into the sea is breaking up much faster than before and spawning huge icebergs, a new study says. The Pine Island Glacier’s ice shelf loss accelerated in 2017, causing scientists to worry that with climate …

Estimates put it at around 1,270 sq km. Greater London is about 1,500 sq km; the Welsh county of Monmouthshire is roughly 1,300 sq km. That’s big by any measure, although not as large as the monster A68 berg which calved in July 2017 from the Larsen C Ice Shelf on the western side of …

The iceberg came from a part of the Antarctic where it is still very cold – the Larsen C Ice Shelf. This is a mass of floating ice formed by glaciers that have flowed down off the eastern side of the Antarctic Peninsula into the ocean. On entering the water, the glaciers’ buoyant fronts lift …

These ice platforms are the floating protrusions of glaciers flowing off the land, and ring the entire continent. The European …

Image caption Major science projects in the deep interior and other remote places will be postponed by a year The British Antarctic Survey is scaling back its research in the polar south because of coronavirus. Only essential teams will head back to the continent as it emerges from winter and virtually all science in the …

Authorisation was given on Tuesday for Europe’s …

Image copyright Dowdeswell et al Image caption It’s amongst the best ocean-floor imagery obtained anywhere around Antarctica Scientists are learning just how fast the ice margin of Antarctica can retreat in a warming world. They’ve identified features on the seafloor that indicate the ice edge was reversing at rates of up to 50m a day …

As the last continent to be discovered and explored, Antarctica has always had its own unique allure. Now the story of the early Antarctic explorers is being brought to life for a new generation. A former Disney animator who worked on Frozen and Big Hero 6 has left Hollywood to create a graphic novel of …
