A23a was one of the largest “megabergs” to be spawned in our lifetimes. When it broke away from the Filchner Ice Shelf into the Weddell Sea in Western Antarctica in 1986, it covered an area of around 4,000 sq km – about the size of Hong Kon...

Global Warming Predicted to Uncover Antarctic Mineral Resources

A new analysis suggests that melting ice, land uplift, and rising sea levels due to global warming will make Antarctica's vast mineral resources, including gold, silver, copper, and iron, more accessible over the next two centuries. The warming climate is expected to expose an ice-free area the size of Pennsylvania.
