Global warming fastest for 20,000 years – and it is mankind’s fault

Global warming is made worse by man-made pollution and the scale of the problem is unprecedented in at least 20,000 years, according to a draft report by the world’s leading climate scientists.

The leaked assessment by the group of international experts says there is now overwhelming evidence to show that the Earth’s climate is undergoing dramatic transformation because of human activity.

A draft copy of the report by a working group of the Intergovernmental Panel on Climate Change (IPCC) states that concentrations of carbon dioxide, methane and other greenhouse gases are at the highest for at least 650,000 years.
