Australian researchers have devised a brilliant idea to turn clouds into giant sunshades to protect the Great Barrier from climate change.
It may seem far-fetched, but scientists are refining a technique that could make clouds more reflective.
Dr. Daniel Harrison, a researcher at the University of Sydney, admits that it's an "out of the ordinary" idea, but if it works, there might be a day-long network of "lightening stations" clouds "around the world. Great Barrier Reef
The technique would see tiny molecules of sea salt, harvested in seawater, sprayed in the air.
Air currents sweep the particles in the low clouds, increasing the amount of sunlight back to the sun.
"A cloud-lit station will blow billions of these nano-sized salt crystals, so small that you would not even be able to see them, and the atmospheric mix will take them fairly quickly up to the level The clouds you want to influence, "Dr. Harrison told AAP on Tuesday.
"It's one of the few options that is scalable to the entire reef, and can buy us some time."
Researchers present their idea at the Cairns symposium on ways to help preserve one of Australia's iconic attractions
Nozzles capable of dispersing sea salt molecules are already being developed, alongside a study to test the feasibility of the concept. It would take a wide range of tools to save reef ecosystems, but ongoing action to combat climate change was paramount.
"We can help buy the reef time, but obviously treat the symptoms, not the cause or the problem." 19659003] The idea of brightening the clouds is one of the many Innovative Approaches Presented at Symposium
Another team is studying the possibility of using an ultrafine biodegradable film, made from light-reflecting materials already found in the marine environment.Applied to the surface of the sea for Shade the corals and limit fading.
