New research from Northumbria University suggests that there is a limited time frame before irreversible, large-scale ice loss begins in Antarctica. According to two recent studies from Northumbria University, there's a limited window of time to prevent large-scale and irreversible melting of Antar

The Antarctic ice sheet was more unstable in its past than initially thought, a group of researchers, including ones from the University of Exeter, said in a new study.

The Antarctic ice sheet was even more unstable in the past than previously thought, and at times possibly came close to collapse, new research suggests.
The findings raise concerns that, in a warmer climate, exposing the land underneath the ice sheet as it retreats will increase rainfall on Antarctica, and this could trigger processes that accelerate further ice loss.
The research is based on climate modelling and data comparisons for the Middle Miocene (13-17 million years ago) when atmospheric carbon dioxide and global temperatures reached levels similar to those expected by the end of this century.
The study was carried out by the Met Office, the universities of Exeter, Bristol, Cardiff and Stockholm, NORCE and the Bjerknes Centre for Climate Research.
