Climate change 'isn't caused by us'

limate change has mainly natural causes and the human contribution is too small to detect, said global warming expert Professor Fred Singer.

He told a debate in London organised by the free market think tank the Institute of Economic Affairs, the climate has not warmed in the past decade, despite the fact carbon dioxide was increasing rapidly. Singer, of the science and environmental policy project at the University of Virginia, told the event the climate has both warmed and cooled over the past century. Burning fossil fuels had enriched the atmosphere with carbon dioxide, because it was what plants live on.

"Maybe we should thank the Chinese for putting more carbon dioxide into the atmosphere instead of worrying about it,"

Singer said one school of thought was the warming of the earth in the 20th century was caused by humans, though greenhouse gases, but he believes that while there must be a human contribution it was not detectable, as it was too small.

He suggested people should be suspicious of any science where there was a consensus and concluded:

"I am not worried about climate change, not at all. We know how to adapt to climate change better than our ancestors, we have the means to adapt to both cold and warm climates.

"The only thing I am scared of is politicians who in their zeal to 'save the climate' will introduce policies that will ruin the economy."

Former chancellor Nigel Lawson, who has set up a think tank called the Global Warming Policy foundation, said technology for adaptation has never been better, and there are huge benefits from a warming planet, including for health and food production. Even if global agreement was reached to decarbonise, it would slow down growth in the world, including in developing countries.

"You are condemning tens and tens of millions in the developing world to unnecessary poverty, malnutrition and premature death and disease."

However, Dr Sam Fankhauser of London School of Economics, a member of the UK Committee on Climate Change, said a target of 50 per cent cut in emissions was both sensible and achievable.

Scientists were 90 per cent sure there was a problem, and it would be unwise and careless not to take precautionary measures.

But the IPCC has no scientific evidence and the theory relies solely on the output of climate models that according to the information in table 2.11 of the 2007 report cannot possibly be accurate.

Surely Dr Fankhauser knows that opinions aren't evidence and that scientific truth isn't determined by votes.

[But the issue's been hijacked by politics, which works precisely that way.

They most costly and liberty restricting scam in history.]
