NASA | Arctic Sea Ice Live Shot 2014

Dr. Tom Wagner from NASA discusses the rapid loss of Arctic sea ice, noting that while this year may not set a new record low, the ice remains thin and diminished. The Arctic is warming twice as fast as the rest of the planet, leading to significant environmental changes. NASA uses satellites and aircraft to study these changes, which may already be affecting weather patterns in the United States. For more information, visit NASA's website.
