Climate change activist goes rogue releasing ‘mini volcanoes’ to cool atmosphere

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. But experts in geoengineering say the launches set a dangerous precedent for private companies or governments to interfere with the planet’s atmosphere. Co-founder Luke Isemans said the potential risks of what he is doing are outweighed by the known threat of climate change. If conducted on a large scale, there are concerns the technique could deplete the ozone layer, or change precipitation patterns.
