Well... the overall sea level isn't rising by any significant amount.
As the ice caps increase, they increase pressure on the ground beneath them. That ground is soaked with water. The pressure squeezes out the water and .... things tend to balance out around the planet.
EXACTLY!
The rise in sea level is within the normal cycles the Earth goes through. Once we hit the next ice age, due any time now, sea level will start dropping.
What will Al Gore and his ilk do then?
