'Make Sunsets' Tweaks Climate By Atmospheric Alteration

Many Sunsets has started sending weather balloons high into the stratosphere, releasing reflective sulfur particles in the belief that this will cool the Earth and save the planet.

Luke Iseman, the cofounder and CEO of Make Sunsets, acknowledges that the effort is part entrepreneurial and part provocation, an act of geoengineering activism...

“It’s morally wrong, in my opinion, for us not to be doing this,” he says. What’s important is “to do this as quickly and safely as we can.”

But dedicated experts in the field think such efforts are wildly premature and could have the opposite effect from what Iseman expects.

“The current state of science is not good enough … to either reject, or to accept, let alone implement” solar geoengineering, wrote Janos Pasztor, executive director of the Carnegie Climate Governance Initiative...

In his 2021 novel Termination Shock, science fiction writer Neal Stephenson describes this same method, as well as some possible problems

The elongated bowl, four thousand feet above sea level, in which this complex had been constructed, was referred to by T.R. as Pina2bo (“Pin a “two bo”). Anyone familiar with the literature on climate change and geoengineering would get the joke. Pinatubo was the name of a volcano in the Philippines that had exploded in 1991. It had blasted fifteen million tons of sulfur dioxide into the stratosphere. The result had been a couple of years’ beautiful sunsets and reduced global temperatures. The two phenomena were directly related. The sulfur from the volcano had eventually spread out into a veil of tiny droplets of H2SO4. Light from the sun hit those little spheres and bounced. Some of it bounced directly back into space—which accounted for the planet-wide cooling, as energy that never entered the troposphere in the first place couldn’t contribute to the greenhouse effect...

Pina2bo would have to operate full blast for many years to put as much SO2 into the stratosphere as its namesake had done in a few minutes...
