[Controversial] A new study contradicts fears that using solar geoengineering to fight climate change could dangerously alter rainfall and storm patterns in some parts of the world.
Published in the peer-reviewed journal Nature Climate Change, the analysis finds that cooling the Earth enough to eliminate roughly half of warming, rather than all of it, generally would not make tropical cyclones more intense or worsen water availability, extreme temperatures or extreme rain. Only a small fraction of places, 0.4%, might see climate change impacts worsened, the study says.
One scientist who read the paper published on Monday said it was not comprehensive enough to conclude that solar geoengineering – most likely involving spraying sulphur dioxide into the atmosphere, thereby mimicking gas from volcanoes and reflecting the sun’s heat – would be safe.
