SIR – It would appear a group of the world’s top 259 scientists from 30 countries, namely the Intergovernmental Panel on Climate Change, after extensive deliberations have concluded that global warming could possibly be the result of human activity. We are almost sure global warming may not be manmade possibly due to the fact there have been no further increases in the planet’s temperature in the past 15 years!

If this revelation came about, is it feasible Britain could once more be largely energy self-sufficient, with the restoration of this country’s mining industry.

This would result in the revival of the present depressed coal-rich communities which formally relied and thrived on its extraction.

Many of your readers will recall when this city produced its very own gas and electricity at a price affordable to most, as opposed to the present day, where consumers are annually held to ransom over energy tariffs. I would be fascinated to discover what theory the Intergovernmental Panel on Climate Change have on what activity brought about sufficient warming of the globe to bring an end of the Ice Age two million years ago?
