Geoengineering without ozone loss

Researchers report a solar geoengineering method based on the injection of calcite particles, rather than the more frequently suggested sulfuric acid, into the stratosphere to mitigate the effects of climate change, and suggest that by neutralizing ozone-destroying acids, which have increased with anthropogenic emissions, this method might help cool the planet while simultaneously healing the ozone layer. - Read at PNAS.org
