C. Trousdell accused me of misrepresenting the truth when I wrote that only 0.6 per cent of the CO2 in the atmosphere is due to motor vehicles.

He quotes a rise of 100ppm in CO2 in the last 200 years, but it should be considered over thousands of years, over which period the rise is insignificant.

The facts I quoted were confirmed by a professor who attended the recent conference on climate change in London.

He said he had used similar arguments with John Prescott and Michael Meacher but the facts of the matter could not sway their opinions.

Global warming is too convenient for the government to give up, so it ignored the announcement by NASA in April that the earth has entered a period of global cooling.

Perhaps it was worried it might have to pay us a reverse fuel tax to warm the earth up a bit.
