Ridiculous article. The Marshall Islands are ATOLLs, which are alive. The coral they sit on is a living mass of sand and fragments that "floats" on seawater--if the seas rise, the Atolls rise as well. This knowledge goes back all the way to Charles Darwin (more of a geologist early on than a Biologist), so there's no excuse for mainstream scientists not knowing it. Here's a nice summary from Austrailian Engineer Willis Esenbach (a noted climate skeptic, BTW):
Since we can't believe skeptics on anything, here's the abstract of a current paper by AGW believers on the same subject, which actually has DATA (imagine that) about coral atoll growth or shrinkage over the last half-century or so:
It would take a far more dramatic rise rate than the current 2-3 mm/year to overrun any of the South Pacific Atolls. Development on the islands, coral mining, killing the symbiotic fish populations (especially parrott fish), and fresh water demand are far more threatening to the Marshalls.
