The ideas may sound like science fiction, but some researchers are seriously considering what it would take to shoot sun-reflecting aerosols into the atmosphere to counter climate change. Fleets of small jet aircraft could fly into the lower stratosphere several times a day and release sulfur gas to produce planet-cooling sulfate aerosols. Or giant balloons made out of plastic could be equipped with long hoses and used to pump sulfur gas upwards into the atmosphere.
