Compared with carbon dioxide, nitrous oxide is 300-fold more potent in terms of its warming potential, though carbon dioxide is a far more prevalent greenhouse gas.
虽然二氧化碳是更为普遍的温室气体，但与二氧化碳相比，一氧化二氮是其致暖潜力的300倍以上。

I have to wonder: Do current estimates of potential reductions in greenhouse gasses take into account the extent to which broadband might reduce commuting and global travel for business?
