Dicey

clipped from www.timesonline.co.uk The British Government estimates the cumulative carbon saving from all its plans at somewhere between 950 and 1,100 million tonnes of CO2 by 2030. Computer modelling - using DICE (dynamic integrated model of climate and the economy) - shows that the net effect of the UK renewables effort is impossibly tiny. The temperature increase by 2100 without Mr Brown's plan would have been 2.4536181C. With the best-case scenario the huge UK effort means that the temperature at the end of the century would be 2.4532342C. The effect is a difference of about 0.00038C - or about one three-thousandth of a degree in a hundred years. This is the equivalent of delaying the temperature increase by the end of the century by a little less than a week.
