Mexico Cracks Down on Solar Geoengineering, Forcing Startup To Pause Operations 47

An anonymous reader shares a report: The tiny startup Make Sunsets, which had been experimenting with releasing sulfur dioxide into the atmosphere to reflect sunlight in order to cool the earth, said Wednesday it would cease operations for the time being and review its approach after the Mexican government cracked down on solar geoengineering. The idea of releasing aerosols into the atmosphere to cool the earth has been around since the 1960's, but it had largely been relegated to science fiction until recently, as the urgency of climate change has become more apparent. The White House is currently coordinating a five-year research plan to study the idea, which is colloquially known as "solar geoengineering," and the quadrennial U.N.-backed Montreal Protocol assessment report for the first time included an entire chapter it.

Luke Iseman, a serial inventor and the former director of hardware at Y Combinator, believed all of that research was not happening fast enough. So he started tinkering with releasing sulfur dioxide particles into the atmosphere with balloons, raised venture capital to fund the startup, and brought on co-founder Andrew Song to manage sales. Make Sunsets was planning to launch three latex weather balloons that would release anywhere between 10 and 500 grams of sulfur dioxide in January. But many industry watchers criticized its plans for being hasty and lacking sophistication. On Friday, the government of Mexico issued a statement that it plans to "prohibit and, where appropriate, stop experimentation practices with solar geoengineering in the country."

It would seem there was no permanent harm done, and some data was generated by this stunt, but that method of geo-engineering has bee

    In Mexico, or in the US, would this ban be based solely on intent? Let's say I created a company to geo-engineer the planet to be *warmer* by releasing large amounts of methane. How am I different from an industrial company releasing the same amount of methane as a byproduct of its industrial processes? Would they technically fall under a "geoengineering ban"?

    • Let's say I created a company to geo-engineer the planet to be *warmer* by releasing large amounts of methane.

      Large methane releases are already illegal almost everywhere. That's why you see flare stacks. In particular with respect to this story, it is definitely already illegal [reuters.com] in Mexico.

    • Because the company releasing methane like that is at least producing goods and services that are desirable. People through the medium of their government at the right to decide what kind of businesses they want to allow to operate and to regulate those businesses to ensure the safety and well-being of themselves and their community. At the same time those people through their government have the right to make trade-offs.

    they're funded by oil and gas companies. They're supposed to make you feel like there's a solution to climate change that doesn't involve renewable energy. It's similar to what the plastic industry did with the recycling industry. Feels not reals. It's a distraction to prevent their assets in oil and gas from being devalued by the switch to renewable energy.
  • Obviously, they should be doing their experiments in the US. Its the American way.

    They're going to release 500g of sulfur dioxide and measure -- um -- nothing?

    If you're good at math that's like 18oz... roughly a beer and a half worth.

    The only likely difference to be measured is how much they take their investors for.

    This is a nothingburger, a no-story, and "Mexico's Government" caring about the environment
    is just a tad funnier than them "fighting crime and the cartels."

    Color me laughing.

        Won't cause enough cooling to measure the temperature effect, but it would be a good calibrated measurement of sulfate aerosol scattering properties.

        Volcanic aerosols are a mix of different stuff.

        • by higuita ( 129722 )

          ok, if this was just a test ... even so, dunno exactly how they would measure 500g of SO2 at high altitude and how much that is different from high altitude plane trails

          • ok, if this was just a test ... even so, dunno exactly how they would measure 500g of SO2 at high altitude

            Look at the reflectivity and the transmission of the resulting clouds in the visible and IR. Hard measurement, but optical measurements are pretty well established, so it should be doable.

            and how much that is different from high altitude plane trails

            Those are water-ice crystals. Different scattering properties.

  • Underqualified Silicon Valley tech bros trying to modify climate, can't see how that will go wrong.

    • I kind of assumed this Luke Iseman guy would be the offspring of some vastly wealthy arseholes who inherited a sense of impunity, but he may in fact be an ok dude. (Albeit completely delusional about this particular idea).
      His personal website for instance lists the various jobs he's had, and schemes he has cooked up and includes stuff like:

      Wetique: Co-founder. Built a website to rate your friends and receive better media recommendations. Outcome: went from idea to working product in 3 months by teaching ourselves everything we needed to build an MVP. Realized we hadn't made something people wanted.

      which at least includes a useful insight.

    • When I saw the term "serial inventor" the first word association that popped into my head was "crackpot". When I saw that he had been at Y Combinator I changed that to "rich crackpot".

  • Rumors about spraying anything over cartel fields might scare away US customers.

    and get out of Mexico to someplace less restrictive. Throw tons of sulphur into the atmosphere, bring the temp down while we work on permanent solutions. This approach is why the chance of actually "burning up" from climate change won't happen, we'll delay that with this simple approach until we've converted 100% to electric everything, and emitting electric nothing, and we'll be as clean as possible. If the temp still goes up, then

    Millions of tons of SO2 are released into the atmosphere every year [un.org]. By some estimates it's keeping the planet about 1C cooler than it would be otherwise.

    The ongoing reduction in SO2 emissions -- such as the required change in sulfur content in ocean freight carriers -- is going to cause global warming to accelerate over the next couple decades.
  • If you want to kill all life on the planet, I cannot think of a better way than to purposefully introduce cooling and wildly overshot your target - as a side effect greatly reducing the ability of life to survive across the planet.

    We are already kind of due for an ice age, PLEASE do not push us into one trying to reduce global warming.

    • That's not the risk at all. There is no imminent danger of global cooling. We're on a rapid warming trend. Read much current, credible, and relevant science?

      Primary risks of geoengineering initiatives to ward off planetary heating are:
      1) They mask the problem, allowing irresponsible continued increase of greenhouse gas emissions into the atmosphere.
      2) Until they don't mask the problem, due to a technical, managerial, financial, or political failure of the geoengineering programme,

  • with all the Nimbys in the US, Mexico was the most likely place to do these experiments.
    Canada is cold as f*** most times of the year so no point in polluting the atmosphere there.

    I guess if I had been born a douchebag I could be rich too, but I'm actually fine remaining relegated to the middle class if that is the tradeoff.
