The Green Party of England and Wales has called for a purge of government advisers and ministers who do not share its views on climate change.

Any senior adviser refusing to accept "the scientific consensus on climate change" should be sacked, it said.

Party leader Natalie Bennett said the rule must apply to all senior advisers, including those with no responsibility for environmental issues.

David Cameron says he suspects recent storms are linked to climate change.

Speaking recently, the prime minister said that while a single weather pattern could not be attributed to climate change, many scientists were talking of a link between the two and the UK should be prepared for more extreme weather.

But some Tory MPs and peers, Lord Lawson being the most prominent, have cast doubt on scientific theories on climate change which argue human activity is predominately responsible for recent rises in global temperatures.

'Emergency'

The Greens are now insisting the government gets rid of any cabinet minister who takes a different view on climate change.

He added: "The real question, that everyone is trying to address is: Is this influenced by man-made activity in recent years?

"There is almost certainly bound to be some influence by man-made activity but we have just got to be rational and make sure the measures we take to counter it do not actually cause more damage."

Ms Bennett said: "We need the whole government behind this. This is an emergency situation we're facing now. We need to take action. We need everyone signed up behind that."

Pressed on the issue, she agreed that even the chief veterinary officer should be removed if he didn't sign up to the view on climate change also taken by the Green Party.

A policy document released by the party said: "Get rid of any cabinet ministers or senior governmental advisers who refuse to accept the scientific consensus on climate change or who won't take the risks to the UK seriously."

Ms Bennett added: "It's an insult to flood victims that we have an Environment Secretary (Owen Paterson) who is a denier of the reality of climate change and we also can't have anyone in the cabinet who is denying the realities that we're facing with climate change."

She said her party took the consensus view shared by many other organisations including the Intergovernmental Panel on Climate Change.

In September, the UN-backed body said it was 95% certain that humans were the "dominant cause" of global warming since the 1950s.

The party also wants to see staff cuts at the Environment Agency reversed, a bigger budget for the Agency and tougher rules to prevent development on flood plains.

It says money spent supporting fossil fuels should be redirected to help victims of flooding.
