Sir - Readers may have come across an apparently publicly funded climate change pressure group called the Climate X-Change which is 'working with' the district and county councils to brainwash us and our children.

One of the more riveting ways they 'demonstrate' the impact of climate change around Oxfordshire schools and communities is a picture of a washing line decorated with Victorian bloomers and modern thongs to 'illustrate' how much warmer the world is getting.

Attention grabbing though it is, like much of the climate change publicity we are fed, it conveys a falsehood. Victorian ladies did not wear big knickers because they were cold but because they were modest - even piano legs were draped in bloomers. Furthermore, before Victorian times, when it is known to have been colder, it was not the fashion for women to wear knickers at all.

Like Al Gore's highly imaginative film which the High Court has insisted should carry a 'truth warning', and the claim that polar bears are dying for lack of ice, the climate change publicity material is riddled with untruths and exaggerations.

We all know that it has been both warmer and colder in the past, and whilst CO2 emissions may have some insignificant effect, any changes will be virtually imperceptible; and the impact we might make with wind-farms or giving up flying would be so insignificant as to be neither measurable nor, of course, worthwhile. It is the climate change brigade, the 'reds in green clothing', not climate change itself, which is the real threat to our way of life and it is high time their bluff was called before it's too late.
