John Kerry actually said...

"If we take the best offering of every country... we would still wind up at about 550 parts per million."

"the balance in judgment of public policy falls on the side of caution and precaution."

"whatever we put up there today is going to continue to do damage for the next 100 years."

"The science is telling us that's wrong, we have to try to stay at 350 parts per million."
