Al Gore warns on latest climate trends | Video on TED.com
This video is about the changing of climate. Burning coal is leading cause of global warming. Our economy, national security, and climate crises are because of carbon based fuels like dirty coal and foreign oil. In 1980 the arctic ice cap from 3 million years has been the size of lower 48 states, but in 2007 it has been shrunk by 40% . The ice is melting fast and a lot of glaciers are becoming lakes because we are putting 70 million tons of CO2 in the oceans every 24 hours.
