The icy, high latitude regions of the world are considered bellwethers of climate change. Retreating Arctic sea-ice is a strong, recent indicator of significant change. Faculty and students within Atmospheric Sciences, Oceanography, Earth and Space Science, and the Polar Science Center at UW's Applied Physics Laboratory) study the changing cryosphere and polar oceans and atmosphere, using field observations, satellite data, modeling studies, climate predictions, and theoretical studies. We study not only observed and predicted changes in the polar regions, but also their influence on lower latitudes and global climate. Here are some papers of the research we do.
