From Scientific American:
In a few short weeks, world leaders will assemble in Copenhagen for the much anticipated United Nations Climate Change Conference. Their goal: to draft an agreement that will limit global warming, chiefly by reducing greenhouse gas emissions. As the 12-day meeting gets closer, the chorus from jaded pundits and politicians gets louder: “It can’t be done.”
Nonsense. The naysayers have two reasonable concerns. One: Countries will never agree on limits because they are out to protect their own interests, which differ. Two: Even if they reach an agreement, it will never hold because it will raise energy prices, which people will resist. Fortunately, both worries can be resolved.
