In theory, it could mitigate the effects of global warming; but experts are wary.

Make Sunsets, a California-based startup, released weather balloons that carried sulfur particles into the stratosphere which possibly burst there, releasing the chemical, MIT Technology Review.


Founded by Luke Iseman, previous director of hardware at Y Combinator, the attempts by the startup fall into the controversial area of solar geoengineering where particles are released into the atmosphere with an aim to reflect sunlight back into space to ease global warming. The field has largely been a thought experiment with no real consensus if the technology can help us fight climate change.
