A California company called Make Sunsets has released sulfur dioxide into the air in order to block out the sun in hopes of eventually cooling the planet.
A startup claims it has launched weather balloons that may have released reflective sulfur particles in the stratosphere, potentially crossing a controversial barrier in the field of solar geoengineering.
Geoengineering refers to deliberate efforts to manipulate the climate by reflecting more sunlight back into space, mimicking a natural process that occurs in the aftermath of large volcanic eruptions. In theory, spraying sulfur and similar particles in sufficient quantities could potentially ease global warming.
It’s not technically difficult to release such compounds into the stratosphere. But scientists have mostly (though not entirely) refrained from carrying out even small-scale outdoor experiments. And it’s not clear that any have yet injected materials into that specific layer of the atmosphere in the context of geoengineering-related research.
That’s in part because it’s highly controversial. Little is known about the real-world effect of such deliberate interventions at large scales, but they could have dangerous side effects. The impacts could also be worse in some regions than others, which could provoke geopolitical conflicts.
The company’s CEO, Steve Iseman, is already being portrayed as some sort of Bond Villain since he went ahead with his project despite other people urging him not to and even Iseman admits that what he’s doing may not be scientifically sound. This will not end well due to the harm inhaling sulfur does to the human body. But that may be the point of his doing this after all.
