More than 115 cases of eye damage reported in Ontario after solar eclipse
More than 115 people who viewed the solar eclipse in Ontario earlier this month experienced eye damage after the event, according to eye doctors in the province.
To slow the speed at which high temperatures and warm waters bleach the corals of the Great Barrier Reef, Australian scientists are spraying droplets of ocean water into the sky to form clouds to protect the environmental treasure.
Researchers working on the so-called Cloud Brightening project said they use a turbine to spray microscopic sea particles to thicken existing clouds and reduce sunlight on the world's largest coral reef ecosystem located off Australia's northeast coast.
The water droplets evaporate leaving only tiny salt crystals which float up into the atmosphere allowing water vapor to condense around them, forming clouds, said Daniel Harrison, a senior lecturer at Southern Cross University, who runs the project.
"If we do it over an extended period of time for a few weeks to a couple of months when the corals are experiencing a marine heatwave we can actually start to lower the water temperature over the Reef," said Harrison.
The project had its second trial in March, the end of the Southern Hemisphere summer when the Reef off Australia's northeast is at its hottest, gathering valuable data on the atmosphere when corals are at most risk of bleaching.
A combination of light and warm water causes coral bleaching. By cutting light over the reef by six per cent in summer, "bleaching stress" would be cut by 50 per cent to 60 per cent on the undersea ecosystem, Harrison said.
But the benefits of cloud brightening would lessen over time unless other measures slowed the march of climate change.
"If we do have really strong action on climate change then the modeling shows that the cloud brightening is enough to stop the reef declining and to actually see it through this period while we reduce our carbon emissions," he said.
One of Australia's best-known natural attractions, the Reef came close to being listed as an endangered World Heritage Site by the United Nations, although it avoided the designation following lobbying by Australia.
