Kaitlin Naughten is an ocean modeller specialising in interactions between the Antarctic Ice Sheet, the Southern Ocean, and the broader climate system. Her research primarily focuses on the future of Antarctic ice shelf cavities in a warming climate. Kaitlin has specialised in regional settings (Weddell Sea, Amundsen Sea) as well as circum-Antarctic and global. She co-developed ÚaMITgcm, one of the first successful coupled ice-sheet/ocean models. She is now a member of the core development team for the UK Earth System Model, the world’s only global climate model with a fully coupled Antarctic Ice Sheet.

15. SO-WISE

    SO-WISE addresses a critical knowledge gap in understanding how warm ocean water reaches and melts the undersides of West Antarctic ice shelves, which is currently the largest source of uncertainty in global sea level rise projections.

1. Increased West Antarctic Ice Sheet melting ‘unavoidable’

   The West Antarctic Ice Sheet will continue to increase its rate of melting over the rest of the century, no matter how much we reduce fossil fuel use, according to British Antarctic Survey (BAS) research published this week in the journal Nature Climate Change.
