2 Billion May be forced to move due to sea level rise due to global warming!

Another unknown, but suspected from historical research in geology and ice cores, is that a tipping point may be reached - such a tipping point will produce a very rapid increase in temperatures and sea level rise due to known mechanisms - only unknown it the point at which such tipping point [or points] kick in.

Another reason for exponential rate is the increase in CH3 from permafrost melting -- a positive feedback loop. Also CH3 has been found to leek at previously unknown rates from natural gas wells. Undersea CH3 is frozen at the bottom of the ocean and is showing signs of melting.

I think we are past a tipping point and the positive feedback loops have kicked in.

One more thing, we are much closer to the first blue water even in the arctic -- the time when the north pole is liquid water.
