Accidentally truthful Kerry:

“The fact is that even if every American citizen biked to work, carpooled to school, used only solar panels to power their homes, if we each planted a dozen trees, if we somehow eliminated all of our domestic greenhouse gas emissions, guess what – that still wouldn’t be enough to offset the carbon pollution coming from the rest of the world.
If all the industrial nations went down to zero emissions – remember what I just said, all the industrial emissions went down to zero emissions – it wouldn’t be enough, not when more than 65% of the world’s carbon pollution comes from the developing world….”    John Kerry
