Understanding extreme weather in Antarctica

ExtAnt started in February 2024 and is a 4 year NERC Highlight Topic project.

Work is around three research aims (RAs):

RA1. Quantify the relative contributions of key drivers of Antarctic extreme events and determine the role of anthropogenic forcing in specific observed cases.
RA2. Resolve present-day trends and variability of extreme events and their impacts: in particular, assess the roles of the ozone hole, GHG concentrations and modes of internal climate variability.
RA3. Quantify the severity and frequency of future Antarctic extreme events, and associated risks related to their impacts on vulnerable ice shelves, and provide information relevant for assessing impacts on ecosystems.
