Outsider:  Damn it, man, I really enjoy arguing with you, and on this one it's really hard.  With population growth, urbanization and industrialization in, as you point out, especially China and India, our "carbon footprint" just keeps growing.  The best we can do is to try to "slow it down."  Unless there's a concerted and coordinated worldwide commitment to address all the factors (including population growth), we're doomed to ever-increasing and ever-accelerating warming. 

Yes, we should do what we can to slow it.  But, at the same time, we'd best make significant strides toward needed long-term adjustments to live with it as best we can.  That includes such things as decreased "waste" of water, and reassessing what locations are habitable....especially, already extremely dry areas and very low elevation and vulnerable coastal regions.  It won't be pretty.   Regards, Gary
