From researching the pace of Alaskan glacier melt to changes in Arctic sea ice, climate scientists trek to the most remote areas on Earth to help us understand our environment. The Juneau Icefield Research Program brings scientists and students together to study glaciers annually. 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. Meanwhile, Michael Mann discusses what might happen to sea levels if we continue burning fossil fuels at current levels.
