Startup Releasing Particles Into Atmosphere To Tweak Climate

Make Sunsets is already making an effort to monetize geoengineering, a move that is expected to draw harsh condemnation. The startup is releasing particles into atmosphere to tweak the climate.

Apparently breaking a contentious barrier in the realm of solar geoengineering, a firm claims to have launched weather balloons that may have dispersed reflective sulfur particles in the stratosphere.

Geoengineering refers to intentional attempts to control the climate by reflecting more sunlight back into space, a natural phenomenon that occurs following major volcanic eruptions. In principle, spraying sulfur and related particles in large enough numbers could help to mitigate global warming.

Such substances are not theoretically challenging to release into the stratosphere. However, scientists have mainly (though not fully) avoided doing even small-scale outside research. And it is unclear whether anyone has yet injected materials into that exact layer of the atmosphere as part o...
