Floods around the UK over the last few weeks are probably connected to climate change, David Cameron told the House of Commons.
He said some colleagues could argue about linking the "abnormal" weather to climate change, but said: "I very much suspect that it is."
Mr Cameron said the government was committed to carbon reduction targets and highlighted government investment in green projects, in response to a question by Lib Dem MP Tim Farron in PMQs.
