Clear consensus among climate scientists on global warming

I WAS rather disappointed to read during my visit to Singapore your very inaccurate and misleading "Dinner-party guide to the climate change debate" ('BT Weekend', July 21-22). On almost every point, Dr Tilak Doshi was wrong about the current state of knowledge.

Contrary to his assertion, there is a clear consensus among the world's climate scientists, based on overwhelming evidence, that continuing emissions of carbon dioxide and other greenhouse gases from human activities, particularly the combustion of fossil fuels, is driving a rise in global average temperature.

This consensus also recognises that global warming is already having impacts, such as regional changes in extreme events, including heavy rainfall, and sea-level rise. And the evidence indicates that if our emissions are not urgently reduced, we risk creating a climate by the end of this century that has not existed on Earth for millions of years. The only reasonable option for us and future generations is to make a rapid transition to cleaner sources of energy than fossil fuels.
