What if the north and south poles melt?
the sea may rise taking more coastline though the air will probably hold some water as to the land so it might not be so bad as some predictions (though more weight on land may cause it to subside and make the oceans appear to rise more than they might)! although as the ice is so cold and contracted there might be more than expected! when its gone there will be less weight on the poles creating some upward lift of the tectonic plates there causing mass earthquakes, volcanic activity which it turn with the pollution we pour into the atmosphere might pretty much destroy it! well done people though so much may be natural!!!
