We have just 100 months to act to prevent dangerous climate change, says Andrew Simms. In this week's Green Room, he outlines plans for a"Green New Deal" that could sort out the pressing problems we have with climate, energy and the financial system.

"Too important to fail" is the message heard repeatedly from governments stepping in and spending billions to prop up failing financial markets.

But all the time, another system - an atmosphere convivial to human civilisation, that really is too important to fail - is being wrecked by political complacency and unrealistic economics.

Now, a unique new group of specialists in finance, energy and the environment are arguing for a Green New Deal that will deliver a comprehensive solution to the triple crunches of the credit crisis, high energy prices and climate change.

But time is short, very short.
