Sir - In seeking to airbrush the 'convenient untruths' in High Priest Gore's movie, your correspondents ignore the High Court's most telling criticism, that Gore's 'apocalyptic vision' was not 'impartial analysis' but 'politically partisan'.

Reckless exaggeration of climate change is a political device to lure us all into begging for the taxes and regulations necessary to advance the green political agenda. Like the reds before them, the greens seek state control of our lives, and the end of market capitalism, promising a successful new economic model to take over from the old.

As with 20th-century Communism, it sounds plausible but it's a myth. There is new business, certainly, in climate consultancies, carbon exchanges and windfarm manufacture; manufacturers are falling over themselves to set up low carbon operations. But none can exist without public subsidy, or artificial taxes and regulations pricing out more cost-effective alternatives.

The UK, or even the EU, embracing the green agenda won't slow global warming but will certainly speed on our recession.

Does recession worry the Greens? On the contrary. 'Bring it on' says George Monbiot, England's Al Gore. Unemployment, avoidable hardship, are objectives in themselves in the delusional green pursuit of some notional pre-capitalist nirvana.

There is however no need for the panic the Greens seek to create, or its inevitable recessionary consequences. Global warming - if it continues - will be a slow process and give time for sensible solutions to any problems it might cause.

There is no place for mass hysteria whipped up by apocalyptic overstatement of the scale and speed of its possible effects, or the economic suicide implicit in the green agenda.
