Darling urges G20 to act on climate change
Speaking ahead of the G20 conference in Scotland, Mr Darling said it will take billions of pounds to combat global warming.
He said: "We either take action and stop those problems happening or we fail to take action and we face bigger costs down the line.
"My message to my fellow finance ministers is there's a job of work to be done here. I don't think anyone seriously denies there's a problem here. Let's get on with it."
The Chancellor, who is hosting a meeting of G20 ministers at St Andrews, Fife, stressed that "heavy lifting" was needed to make progress on the issue.
Despite the current financial turmoil, Mr Darling said investing in the fight against global warming was crucial.
