SIR – The myth that man is responsible for global warming continues to fall apart on an almost daily basis.

First we had the falsification and manipulation of computer data by climate scientists at the University of East Anglia.

Now claims by the world’s leading climate scientists that most of the Himalayan glaciers will vanish within 25 years have been exposed as pure nonsense.

This alarmist warning appeared in a report by the Intergovernmental Panel on Climate Change, and was based on no more than speculation by just one scientist from a University in Delhi.

It has now been established beyond doubt there is absolutely no evidence to support this theory and the IPCC has lost even more of its credibility.

The IPCC is exactly what it says – a group of scientists sponsored by various governments to provide the data on climate change that governments want to hear.
