The effects of climate change are already being felt in many parts of the world and it is the most vulnerable who suffer the most. The industrialised nations, who produce the majority of carbon dioxide and other greenhouse gases, are wealthy and more able to cope with the changes.
The challenge is to find ways of helping developing countries in ways that do not add to the problem.
These pages look at different ways in which climate change is affecting communities and how steps are being taken to bring sustainable development to help cope with the problems caused by climate change.
