A Startup Is Releasing Particles Into the Atmosphere To Tweak the Climate 147

An anonymous reader quotes a report from MIT Technology Review: 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. [...] Some researchers who have long studied the technology are deeply troubled that the company, Make Sunsets, appears to have moved forward with launches from a site in Mexico without any public engagement or scientific scrutiny. It's already attempting to sell "cooling credits" for future balloon flights that could carry larger payloads. Several researchers MIT Technology Review spoke with condemned the effort to commercialize geoengineering at this early stage. Some potential investors and customers who have reviewed the company's proposals say that it's not a serious scientific effort or a credible business but more of an attention grab designed to stir up controversy in the field.

Luke Iseman, the cofounder and CEO of Make Sunsets, acknowledges that the effort is part entrepreneurial and part provocation, an act of geoengineering activism. He hopes that by moving ahead in the controversial space, the startup will help drive the public debate and push forward a scientific field that has faced great difficulty carrying out small-scale field experiments amid criticism. "We joke slash not joke that this is partly a company and partly a cult," he says. Iseman, previously a director of hardware at Y Combinator, says he expects to be pilloried by both geoengineering critics and researchers in the field for taking such a step, and he recognizes that "making me look like the Bond villain is going to be helpful to certain groups." But he says climate change is such a grave threat, and the world has moved so slowly to address the underlying problem, that more radical interventions are now required. "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."

[...] By Iseman's own description, the first two balloon launches were very rudimentary. He says they occurred in April somewhere in the state of Baja California, months before Make Sunsets was incorporated in October. Iseman says he pumped a few grams of sulfur dioxide into weather balloons and added what he estimated would be the right amount of helium to carry them into the stratosphere. He expected they would burst under pressure at that altitude and release the particles. But it's not clear whether that happened, where the balloons ended up, or what impact the particles had, because there was no monitoring equipment on board the balloons. Iseman also acknowledges that they did not seek any approvals from government authorities or scientific agencies, in Mexico or elsewhere, before the first two launches. "This was firmly in science project territory," he says, adding: "Basically, it was to confirm that I could do it." The company is already attempting to earn revenue from the cooling effects of future flights. It is offering to sell $10 "cooling credits" for releasing one gram of particles in the stratosphere -- enough, it asserts, to offset the warming effect of one ton of carbon for one year. "What I want to do is create as much cooling as quickly as I responsibly can, over the rest of my life, frankly," Iseman says, adding later that they will deploy as much sulfur in 2023 as "we can get customers to pay us" for. The company says it has raised $750,000 in funding from Boost VC and Pioneer Fund, among others, and that its early investors have also been purchasing cooling credits.
Shuchi Talati, a scholar in residence at American University who is forming a nonprofit focused on governance and justice in solar geoengineering, was highly critical of the company's scientific claims, stressing that no one can credibly sell credits that purport to represent such a specific per gram outcome, given vast uncertainty at this stage of research.

"What they're claiming to actually accomplish with such a credit is the entirety of what's uncertain right now about geoengineering," she says. Talati adds that it's hypocritical for Make Sunsets to assert they're acting on humanitarian grounds, while moving ahead without meaningfully engaging with the public, including with those who could be affected by their actions. "They're violating the rights of communities to dictate their own future," she says.

      Thats why the fucker is doing it in mexico instead of california.

      Its *stupid*. Of all the geoengineering ideas, sulphur is the worst, because of ocean acidity (which, btw reduces the oceans ability to absorb CO2).

      Like fuck, at least do one of the safer experiments. Water vapor towers around the arctic. Raise the albedo, slow down warming of greenland and the siberian permafrost. At least with that idea, if it backfires you just stop doing it.

      • Yeah if he's using something that can worsen ocean acidity, a problem which already goes completely unabated by any kind of SRM efforts, then he's ruined a trolling masterstroke with legitimate ecological concerns. Mind you an average semi-truck probably releases more of this stuff over the course of a normal work day than one of these balloons and nobody's batting an eye...

      • So a lot of ultrasonic humidifiers running at the same time in the artic will make the temperature go down? Let's do it, pronto!
        • The concepts a bit less low tech. You basically build a big bunch of giant chimneys on barges in a ring around the arctic, and just spray seawater into the air.

          There was a study on it once that priced the towers at about 2mil each, and you'd build a few hundred of them, and they calculated you could drop the temps around the arctic by about 2c.

    With no monitoring gear on the test at all, plainly all the launches were for was to get attention... attention for investor dollars, which they can basically run off with by claiming that a $1 mylar balloon costs $1 million to assemble and launch, and in tern provide valuable carbon credits for investors.

    No way this is not a giant scam.

      A balloon which actually does the job costs maybe $100-$200 hundred bucks rather than $1. Monitoring equipment would be another couple hundred but be reusable. Ham clubs do this all the time.

      The amount of carbon he's claiming to offset is sketchy but otherwise there is no need for it to be a scam.

    Off the top of my head, which I should know because of what I do for a living, I'm like 99% sure they're violating a UN treaty banning large scale, long term atmospheric modification here.

    I wonder who arrests them? I guess Mexico is a signatory to the treaty so they're probably obliged, and it doesn't sound like these morons have enough bribe money to keep them out of jail.
    • I'm like 99% sure they're violating a UN treaty banning large scale, long-term atmospheric modification here.

      1. What UN treaty? Citation needed.

      2. They aren't doing anything "large scale". "Micro scale" is more accurate.

      3. They aren't doing anything "long term" either. SO2 has a mean lifetime in the atmosphere of ten days.

      UN treaties carry no force of law. Nations then, on a voluntary basis, implement their own laws in order to comply with the terms. Even if they have beyond some policy changes it is unlikely anyone goes around enforcing them unless there is some kind of highly visible public backlash.

    "there was no monitoring equipment on board the balloons"

    What a shit experiment.
    • So, all they really know is that they released some balloons. They have no way of knowing whether any of them functioned properly and actually released anything into the stratosphere. In fact, does anyone have any evidence that the balloons carried any sort of real payload?

      • He says he did it to see if he could. So he was the audience for the test. He has memory of if he put the stuff in, or not, and if he released it, or not. That memory will serve as effective evidence for himself, the entire audience. If the balloon contained the amount of helium he believed it did, then it most likely released the contents at the intended altitude. It isn't exactly rocket science.

        Everybody wants to criticize him, but much of the criticism is... weak, and lacks critical thinking.

        • by Shaitan ( 22585 )

          Was his ability to put the stuff in and let go of the balloon in doubt? Because that is all there is to 'he could.' It seems to me the purpose of the experiment was PR.
