Chasing ice: how ice cores shape our understanding of ancient climate

Tas van Ommen, Australian Antarctic Division

Ice cores tell us vital information about how the world’s climate has changed - and how it will change in the future.

The Totten Glacier, the largest in East Antarctica, has deep channels running beneath it that may allow relatively warm water into its belly. Tas van Ommen

Melting moments: a look under East Antarctica’s biggest glacier

Tas van Ommen, Australian Antarctic Division

Researchers in East Antarctica have surveyed an area the size of New South Wales to study the behaviour of the region’s biggest glacier - and the secrets below the ice that could speed up its melting.

Volcanic history of the Antarctic helps with future climate models

Todd Shilton, The Conversation

An international study of ice cores has helped researchers pave the way for a better understanding of how Antarctica’s volcanoes have affected the global climate over the past 2,000 years. The research…

Last Antarctic ice age melt began earlier than first thought

Sunanda Creagh, The Conversation

The Antarctic warming that signalled the beginning of the last ice age melt may have actually started between between two and four millennia earlier than previously thought, a new study has found. Previously…
