Climate Change

storms and floods. Europeans see it in disappearing glaciers, forest fires and fatal heat waves.

Scientists see it in tree rings, ancient coral and bubbles trapped in ice cores. These reveal that the world has not been as warm as it is now for a millennium or more. The three warmest years on record have all occurred since 1998; 19 of the warmest 20 since 1980. And Earth has probably never warmed as fast as in the past 30 years - a period when natural influences on global temperatures, such as solar cycles and volcanoes should have cooled us down. Studies of the thermal inertia of the oceans suggest that there is more warming in the pipeline.

Climatologists reporting for the UN Intergovernmental Panel on Climate Change (IPCC) say we are seeing global warming caused by human activities and there are growing fears of feedbacks that will accelerate this warming.
