Global warming positions of hopefuls for US presidency are sad and tragic, says Klaus

The Czech president, Václav Klaus, has described the views on climate change of the three people in the running for the US presidency as sad and tragic. Mr Klaus made the comments in Washington after an event at which he presented the English-language version of his book Blue Planet in Green Shackles. In it he questions the commonly held view that mankind is responsible for global warming. The Czech president said he hoped John McCain, Barack Obama or Hillary Clinton would tone down their current views on climate change if elected to the White House.
