"That is a crisis in terms of our ability as a nation to do the work we need to do to inform the policymakers, but also just to show that we take Antarctica seriously."

Antarctic research jeopardised by 'terminating' funding, scientists say

Australia's ability to conduct strategic, in-depth, and long-term research in Antarctica is being compromised by "terminating" funding models for key programs, scientists warn.

"The rocks that the glacier sits on impact the way it behaves, the heat that’s coming through the crust impacts the way that glacier behaves."
