Some ways that we might lose the Global Warming Sweepstakes

There are more than a few ways that this debate can end.  The Earth's
climate might warm up enough so that emission limits are moot.  The Earth's
climate might warm up enough that the ice caps start melting, covering the
polar seas with cold fresh water, which might change ocean circulation so
as to cool the Earth's climate below the current level.  This would lead to
an interesting debate,  eh?  Do we pump out even more greenhouse gases so
as to return to "normal", and take the risk of rocketing beyond?  Or try to
stabilize to that level and hope we like the end climatic state?  Or what? 
We might even decide to do the right thing and stabilize levels of
greenhouse gases.
