Geoengineering could save coral reefs, among the ecosystems most at risk because of climate change, better than I would be able to make a drastic reduction in CO2 emissions. The thesis to a study published in the journal ‘Nature Climate Change’, in which an international team of researchers focuses on a technique called Solar Radiation Management, management of solar radiation, which involves injecting gas into the stratosphere to form microscopic particles can to reflect some of the sunlight and thus to limit the increase of surface temperature of the sea.
The rising temperatures, along with ocean acidification, is the main threat to the survival of coral reefs, as Because the so-called “bleaching” which can lead to coral death. According to experts of the Carnegie Institution for Science and the University of Exeter, also hitting the most ambitious goal of the Intergovernmental Panel on Climate Change (IPCC) on the reduction of CO2, by the middle of this century there will be a severe and widespread coral bleaching.
“The reefs are facing a dramatic situation, no matter how intensely now decarbonizza the economy,” says Peter Cox of the University of Exeter. “There is a direct choice between the conventional mitigation and climate engineering, but this study shows that either we have to accept as inevitable the loss of a large proportion of coral reefs in the world, or we have to start thinking beyond the mitigation CO2 emissions “.
