For the information of Dr Martin Rodger (30th Jan),we still get around five pre cent of our total energy from coal.

It is essential for the steel industry and it is also used in cement kilns.

It seems that facts are not of interest to him.

Instead of answering my points about the defects in the claims about climate, he simply resorts to name-calling.

The Scientific Method is to subject proposed theories to reasoned discussion.

In the 1950's, people used to blame the dreadful weather of that decade on the many nuclear weapons tests.

Using that decade as baseline, it is easy to say that this is a hot decade.

It should also be pointed out that the 1920's was a very warm decade.(famous photo of dust storm in USA).
