Czech President Vaclav Klaus has criticised climate change campaigner Al Gore, saying: 'I don't think that there is any global warming.'

Mr Klaus, in Davos, Switzerland for the World Economic Forum, made the comments on the sidelines of the conference.

The 67 year old president, whose country holds the rotating presidency of the European Union, said he had not been given any statistical data to prove the Gore theories on global warming.

Referring to the former US vice president, a well-known global warming activist who attended Davos this year, Mr Klaus said he was sorry that Al Gore had not been willing to listen to any competing theories.

Mr Klaus said he was he was more worried about the reaction to perceived dangers of global warming than the consequences.

He said some global warming theories were alarmist and likely to be misused for radically constraining the functioning of the markets and market economy.
