Well all you needed to see was this to know this is total nonsense. Just another fraudulent Chicken Little panic attack to justify the continuing raping of the Taxpayers pocket book by the Junk Scientists.
Let's see. Since the 1960s, Pollution, Overpopulation, Peak Oil, Global Cooling, Starvation, Killer Bees, Aids etc etc etc ad nausea have been the coming global Armageddon.
Funny thing, after raping the Taxpayers for years on this hysteria, the doom and gloom pronouncements magically vanish until the next media manufactured hysteria is needed to pump up Junk Scientist budgets.
This is an unwarranted attack. Do a little research yourself and find out if the threats to coral reefs are real or not (hint: they are). Your attitude in this case is a bit too head-in-the-sand.
Actually, there is a real danger to coral reefs, but it's mostly from the murky water caused by agricultural runoff. Water temperatures a few degrees higher won't kill coral - it actually makes a lot of species really flourish.
