We all talk so much about the artic meltdown but much less about antartica , yet that's the worst problem we face. Most industrial and economic activities goes on in the northern hemispere that's why it's melting down faster up north then south.

But the worl is one, and there is no wall barriers at the equator , not denying a lesser rate of heat exchange between north and south hemispheres then between east and west for the obvious reason of the earth rotation. Both the air and the seas are warming and nobody will laugh either in New-York or L.A. when the water gets in the streets .

There's a common misperception that melting of the polar ice caps will lead to a rise in ocean levels. It won't.

Archimedes' principle: "Any object, wholly or partly immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object."

Floating ice displaces a volume of water equal to it's mass, hence no net change. Where you WILL see an increase is from land ice such as glaciers or the land based portion of antarctic ice, but at the same time, any rise in global temperature will lead to higher evaporation rates which would tend to offset the effect.

Curiously, Jim Puplava (a voice I greatly respect) doesn't put much stock in global warming, in fact he's had several credible guests on his show who point to global cooling as the central issue, and not something we can change either, since it's being driven by the sun's effect on ocean temperatures - essentially the underlying cause of ice ages.

The book's still open on this question IMO. Meanwhile, there are significant changes in ocean PH levels occurring that ARE directly attributable to us - specifically runoff from agricultural fertilizers and sewage entering continental shelf areas where the majority of ocean lifeforms live. This is a catastrophe in the making far worse than anything presently keeping Al Gore up at night.
