From researching the pace of Alaskan glacier melt to how changes in Arctic sea ice affect our weather, climate scientists go to some of the most remote areas on Earth to help us understand our environment. The Juneau Icefield Research Program brings scientists and students together annually to study glaciers. Jeff Barbee reports on the 2013 JIRP expedition. Julienne Stroeve of the National Snow and Ice Data Center looks at the impact changes in Arctic sea ice may have on weather patterns. Michael Mann on what we might expect to see happen to sea levels, if we continue burning fossil fuels at current levels.
