If the Intergovernmental Panel on Climate Change is right, our planet is heading for some big upheavals. By 2100, they predict, global sea levels will have risen by 9cm to 88cm, and average temperatures will be about 1.5 to 5.5C higher than now.

Arctic regions are warming twice as fast as the rest of the world - a trend marked by melting glaciers, shrinking sea ice and climatic changes that are turning solid ground into swamps, exposing coastal villages to erosion and threatening wildlife.
