Dr Andrew Baird of the ARC Centre of Excellence for Coral Reef Studies and James Cook Universities stated, “It is certainly the worst coral die-off we have seen since 1998. It may prove to be the worst such event known to science. So far around 80% of Acroporacolonies and 50% of colonies from other species have died since the outbreak began in May this year.”
He also added, “My colleagues and I have high confidence these successive ocean warming episodes, which exceed the normal tolerance range of warm-water corals, are driven by human-induced global warming. They underline that the planet is already taking heavy hits from climate change – and will continue to do so unless we can reduce carbon emissions very quickly.
So what happened in 1998 and 2010? Apparently Mr. Baird believes that warm water is driven by CO2 induced global warming, but only during certain select years.
…… Which happen to coincide with large El Niño events.
