Because he was once an environmentalist and a famous broadcaster, David Bellamy is used as the mascot of climate change deniers all over the world. Like most mascots he is cute, furry and apparently incapable of rational thought. He has claimed that global warming is "poppycock", that "the global warmers are telling lies – carbon dioxide is not the driver" and that "555 of all the 625 glaciers under observation by the World Glacier Monitoring Service in Zurich, Switzerland, have been growing since 1980" (the WGMS responded that this was "complete bullshit").
He maintains that "since I said I didn't believe human beings caused global warming I've not been allowed to make a TV programme." This is odd because he stopped making TV programmes in 1994. He was making public statements in support of mainstream climate science until at least 2000, and his first public statement to the contrary was in 2004. But the conspiracy extends even further. "Have you noticed there is a wind turbine on Teletubbies?", he asked in the Daily Express. "That's subliminal advertising, isn't it?"
