Greenpeace UK executive director John Sauven has said that it has been clear for many years that "climate change loads the dice in favour of more frequent extreme weather events like floods."
Mr Sauven said that the "Government's own experts are making the link" meaning that the "the climate-sceptic quacks at the heart of David Cameron's Cabinet have nowhere left to hide".
He said: "Far from being an eccentric intellectual quirk, climate change denial is a grave risk to the future well-being and security of the people of Britain."
He said that the Government's failure to invest in making Britain more resilient to the impacts of climate change is a "grave blunder that should trigger immediate questions about the competence of the ministers in charge".
