UK Scientist 'gagged' by No 10 after warning of global warming threat

Downing Street tried to muzzle the Government's top scientific adviser after he warned that global warming was a more serious threat than international terrorism.

Ivan Rogers, Mr Blair's principal private secretary, told Sir David King, the Prime Minister's chief scientist, to limit his contact with the media after he made outspoken comments about President George Bush's policy on climate change.

In January, Sir David wrote a scathing article in the American journal Science attacking Washington for failing to take climate change seriously. "In my view, climate change is the most severe problem we are facing today, more serious even than the threat of terrorism," he wrote.
