Oh and we are only talking a couple of degrees per hundred years. You won't notice the heat differential but the balance is upset and ice caps melt and seas rise and El Nino causes chaos.
Quite wrong Joe. If the Arctic ice cap was to completely melt tomorrow, the seas would actually go down. Water expands when frozen. As the North Pole is actually frozen sea, it would cause the waters to recede across the world...... Now,, if the Antarctic ice was to melt then sea levels would indeed rise, as this body of ice is sitting on top of land. So all we have to do is build extremely large freezer plants in Antarctica to keep it frozen... End of problem.
