University of Melbourne: The Great Barrier Reef is dying. Is it time to engineer the climate?

"In the absence of a sudden and rapid reduction in global greenhouse gas emissions, recovery options are few and tenuous.  In fact, that’s a generous assessment.  We have basically reached the point where anything that provides a glimmer of hope is “worth a crack”. One such proposal is to cool the ocean around the reef by “brightening” clouds overhead.  Modelling and measurements indicate that increasing cloud cover and density would reduce water temperatures around the reef, although whether the effect is sufficient to arrest coral bleaching is uncertain."
