Hey, maybe this is the answer I've been looking for.
Does anyone else think that the reason the dinosaurs were so big is because the earth's gravity was different? I know they say that the reason was their diet, whatever!! I have read that the Pterodactyl should not have been able to fly in this gravity. My point being, was it this gravity shift that killed them all? Was the earth's gravity different then? I really think so. I just can't buy this "diet" crap.

Mostly the article says that sea level increases would not be as much as previously claimed. But I don't get the bit about gravity shift.
If and when the WAIS melts the mass of ice doesn't vanish it turns to water. Why would that water decide to move to the northern hemisphere? Even if it did there is not enough mass to make a significant difference.
The mass of all Antarctic (not just the WAIS) ice is around 2.72 * 10^19 kg. That is about .00046% of the total mass of the Earth. Even if all of the ice in Antarctic were moved to the northern hemisphere it would not make a noticeable difference in Earth's gravity field.
