Decline of Great Barrier Reef Provokes Calls for Geoengineering Techniques

Altering clouds and artificially increasing water movement around stressed corals are two radical solutions that scientists are looking at in order to preserve the Great Barrier Reef.
Back-to-back coral bleaching events, caused by abnormally high sea surface temperatures, have devastated the UNESCO world heritage site, turning once-colourful coral bone white and killing vast swathes of the ecosystem at its northern reaches.
Aerial surveys conducted early this year found severe bleaching had hit two thirds of the reef for the second time in 12 months.
With climate modeling suggesting things are only going to get worse, scientists are looking at a number of ways to engineer a solution.
