Google has put together a set of maps for its Google Earth application that model and simulate the effects of climate change on the planet. In a introductory video, narrated by Al Gore, the company has outlined how the planet could change as a result of human emissions.
Data from the IPCC was turned into a series of layers for the lapping product that show a range of expected temperate and precipitation changes depending on how the human population of the world reacts to the threat.
If you don't have Google Earth you can also view the changes on a special website that the company has put together for that purpose. There's a link to that below.
