Czech President Vaclav Klaus sharply criticized a U.N. meeting on climate change on Tuesday at which U.S. President Barack Obama was among the top speakers, describing it as propagandistic and undignified.
"It was sad and it was frustrating," said Klaus
"It's a propagandistic exercise where 13-year-old girls from some far-away country perform a pre-rehearsed poem," he said. "It's simply not dignified."
Klaus said there were increasing doubts in the scientific community about whether humans are causing changes in the climate or whether the changes are simply naturally occurring phenomena.
"The train can't be stopped and I consider that a huge mistake," Klaus said.
Klaus published a book in 2007 on the worldwide campaign to stop climate change entitled "Blue Planet in Green Chains: What Is Under Threat -- Climate or Freedom?"
In the book, Klaus said global warming has turned into a new religion, an ideology that threatens to undermine freedom and the world's economic and social order.
