Minimizing Climate Uncertainty

Professor Hélène Seroussi is first author on "Insights into the vulnerability of Antarctic glaciers from the ISMIP6 ice sheet model ensemble and associated uncertainty" published in The Cryosphere. "These results come from an international effort that I led to understand the sources of uncertainty in projections of ice sheet contribution to sea level rise, and highlight the need to continue improving ice flow models," says Seroussi.
