Climate change: In graphics

Graphic depictions of the IPPCs predictions for emissions scenarios for the turn of the century. One way or another it is going to be hotter.

It is "very likely" that human activity is the cause for climate change, scientists from over 130 countries have concluded. The graphics below illustrate their predictions on just how much global temperatures may rise over the next century.
Heat maps

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. The broad range of outcomes they show is displayed in the charts below.


Carbon dioxide is the main greenhouse gas, its rise since the industrial revolution is clear. Burning coal, using oil and deforestation
