Sulphate injections are one of several “geo-engineering” solutions to climate change being discussed by scientists. But data published in Science journal suggests the strategy would lead to drastic thinning of the ozone layer. This would delay the recovery of the Antarctic ozone hole by decades, and cause significant ozone loss over the Arctic, say US researchers.
