Coral Reefs Could Be Decimated by 2100 - ScienceNOW
Nearly every coral reef could be dying by 2100 if current carbon dioxide emission trends continue, according to a new review of major climate models from around the world.Flashback » Ocean Acidification: Photographs from Bob Halstead and a Note from Floor Anthoni
"If we are on the [business as usual] emissions trajectory, then the reefs are toast," Caldeira says. In that case, all the reefs in the study were surrounded by water with Aragonite saturation below 3, dooming them. In that scenario, Caldeira says, "details about sensitivity of corals are just arguments about when they will die."
The shallows near Dobu Island off Papua and New Guinea have active underwater fumaroles pumping out virtually pure CO2. The sea grass is extraordinarily lush and healthy and there is very healthy coral reef a few metres away.
