From Agence France-Presse, we see an article saying the world's coral isn't dying off after all.
A team at Sydney University has published research indicating that present levels of calcification are not in decline, and are in fact at 19th Century levels.
The Great Barrier Reef is still in trouble, though. Researchers had pinned the blame on rising sea temperatures, but now I'm wondering if anyone has measured the organic matter content of the water. If currents have shifted, and water's coming in from the mid ocean, maybe it's very low in stuff for the coral to eat.
(Indeed, if all it needs is supplemental food, there may be a market for something like Purina coral chow.)
