The Arctic Ocean Could Experience its First Ice-free Day Before 2030

Dr. Alexandra Jahn is an Associate Professor in Atmospheric and Oceanic Sciences and Institute for Arctic and Alpine Research at the University of Colorado Boulder. Her research topics include climate and paleoclimate modeling, polar climate, climate model evaluation, Arctic Ocean and sea ice variability, Arctic freshwater dynamics, cryosphere, and oceanography. Some of the largest climate changes today are occurring in the Arctic Ocean. Given that observational data in the Arctic is very limited, model studies are a great tool to better understand Arctic climate processes and their global impacts. One of her main research aims is to understand the role of natural variability versus forced trends in the Arctic ocean and sea ice system during the 20th and 21st century. In this work, she investigates the Arctic sea ice and oceanic freshwater dynamics.
