Asked if the world is taking carbon capture and storage seriously, Lord Stern responds "Not seriously enough. This is a moment we need to ramp up. … We are moving into territory where 3 degrees [Celsius of warming] is quite likely, and we haven't been there since three million years ago," or before modern humans—and certainly modern human civilization—existed.
"The most important thing that countries have to do is to take steps to progressively transform the energy base of their economy," said U.S. climate envoy Todd Stern during a press briefing on December 8. " You need to use less energy through efficiency and to develop renewable energy sources more." But even if such efforts are successful, the U.S.—and the world—will also need carbon capture and storage if it is to meet the goal of keeping global average temperatures from rising to dangerous levels.
