Experts in geoengineering say sulphur particle launches set dangerous precedent for private companies to interfere with planet’s atmosphere
A Mexico-based startup will next week launch sulphur particles into the stratosphere in a “rogue” move to create a “mini-volcano” effect it says could help cool the planet.
The technique, known as stratospheric aerosol injection, mimics the impact of volcanoes by using a weather balloon to release sulphur, creating a cloud of particles that reflect the sun’s rays and have a cooling impact.
It is one of several geoengineering techniques being studied as a way to cool the planet to avoid breaching internationally agreed limits on global warming.
