Fresh Water in the Arctic -- Changing Planet

Scientists are concerned that melting Arctic sea ice will increase the amount of fresh water in the Beaufort Gyre, which could spill out into the Atlantic and cause major climate shifts in North America and Western Europe. The Changing Planet series explores the impact that climate change is having on our planet, and is provided by the National Science Foundation (http://science360.gov/series/Changing+Planet/) & NBC Learn (http://www.nbclearn.com/changingplanet) For related lesson plans, visit the Windows to the Universe project team at the National Earth Science Teachers Association at http://www.windows2universe.org/earth/changing_planet
