Are fixing the climate and the ozone layer mutually exclusive?
A geoengineering scheme to solve climate change could hurt the Antarctic ozone layer, while recovery of the ozone hole could increase Antarctic warming, new research suggests. A study published Thursday in Science decries suggestions to solve climate change by spewing sulfur into the atmosphere, saying that such a scheme would wipe out the Arctic ozone layer and delay the healing of the ozone hole over Antarctica for up to seven decades. But hey, maybe that’s not all bad: A paper to be published in Geophysical Research Letters suggests that a full recovery of the Antarctic ozone hole could amplify warming in that region. So … basically, we’ve just really screwed things up.
