Geoengineering may be used to combat global warming, experts say: The Guardian

The authors of the new 1.5C study by the Intergovernmental Panel on Climate Change say there is high agreement that the injection of millions of tonnes of sulphur dioxide into the stratosphere could help limit temperature rises to the most ambitious target of the Paris accord.
