Geoengineering effort to brighten clouds, protect corals

"a research team led by the Sydney Institute of Marine Science and Southern Cross University successfully trialled world-first ‘cloud brightening’ technology off the Townsville coast to protect our valuable reef systems from future bleaching events... 'Cloud brightening could potentially protect the entire Great Barrier Reef from coral bleaching in a relatively cost-effective way, buying precious time for longer-term climate change mitigation to lower the stress on this irreplaceable ecosystem,' Dr Harrison said. 'Microscopic sea water droplets are sprayed into the air, evaporating leaving just nano-sized sea salt crystals which act as seeds for cloud droplets, brightening existing cloud and deflecting solar energy away from the reef waters when heat stress is at its maximum.'"- Excerpt from Southern Cross University.
