The prime minister's new parliamentary adviser on climate change, George Eustice MP, has committed the hanging offence of suggesting that global warming sceptics should be heard in public:
Science questioning climate change should not be "rubbished or ridiculed", a Westcountry MP charged with devising energy policy for David Cameron has said.
George Eustice, Conservative MP for Camborne and Redruth, says he believes there is a link between carbon emissions and warming the planet, but argues "all perspectives" should be heard.
On its own, the statement doesn't amount to very much, but as another sign of a gradual change, it's all to the good.
