Learn about climate change in this Google Earth introductory tour narrated by Al Gore, the first in a series of Google Earth tours leading up to the UN Climate Summit in Copenhagen in December. For more climate change tours, visit http://www.google.com/cop15

In order to understand more about what the human impact of high-end climate change might be, and, therefore, what would happen if a successful agreement can not be reached at Copenhagen, the the climate research team at the United Kingdom’s Met Office Hadley Centre has produced a map outlining some of the impacts that may occur if the global average temperature rises by 4 °C (7 °F) above the pre-industrial climate average.
