I’ve been gripped by the story of Antarctic ‘ice cliff instability’ ever since Rob DeConto and Dave Pollard published their controversial predictions last year. So what evidence do we have that the Antarctic ice sheet could, or would, collapse this century? Confusingly, these are named ‘marine ice sheet instability’ and ‘marine ice cliff instability’. Broadly speaking, both are based around the idea that the thicker the edge of the ice sheet, the faster ice can be lost into the oceans. But there is little consensus in the scientific community about how this ice cliff instability could behave.
