The Intergovernmental Panel on Climate Change predicts that temperatures are most likely to rise by 1.8C-4C by 2100. But the possible range is much greater; 1.1C-6.4C. The maps above show how a range of three different scenarios will affect different parts of the planet.
The emissions scenarios, A1B, A2, B1, used to create the maps above, are based on a range of detailed economic and technological data. These versions of the future consider different population increases, fossil and alternative fuel use, and consequent CO2 increases.
