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/changing_planet.html
