    Emphasis on “tiny” adjustments, per the article. I don’t think Elmo comprehends just how much surface area is going to be required to make any measurable let alone meaningful impact, nor the cost of hefting all of that mass up there and keeping it there.

    This whole crackhead idea is completely infeasible. But he probably hopes it’ll help him scam the government out of a bunch of money trying (and failing), while wasting vast amounts of rocket fuel.

      Usually when people talk about this kind of thing, they suggest making a sun shade and delivering it to the Lagrange point between the earth and sun. It certainly feels more reasonable to do it that way. But I wonder which method really is more feasible. (Obviously both methods aren’t realistic right now)

        Well, two things about that.

        One, the L1 Lagrange point between the Earth and Sun is further out than the orbit of the moon. Even without doing any math, just a cursory observation of how shadows work will illustrate that, given that the moon itself can just barely cover the disc of the sun from where it is, any such object placed there would need to have a diameter larger than that of the moon in order to completely block the sun’s light. Or some appreciable and nontrivial fraction of the diameter of the moon if you only want to block part of the sun’s light. Lofting something that massive up there and more importantly keeping it there given that it’d also be well within the gravitational influence of the moon would be quite the challenge. (“Quite the challenge,” by the way, is rocket scientist talk for, “This is complete science fiction, and whoever suggested it is insane.”)

        Point two is that the Deep Space Climate Observatory is currently already parked there.

          You wouldn’t be blocking all of the suns light. That’d kill us. Blocking 2% would be a noticeable “fix”. It’s been a thought out on paper project for decades. It’s “possible” in the strictest sense, but would take something (or many smaller somethings) the size of most of South America to do. It would take thousands of launches to a destination around 800,000 miles away, and then it would also all have to be able to adjust for orbital changes because the lagrange point isn’t a stable orbit.

          We just need another massive once a millennium volcano eruption. Throw the world into chaos and starve half the population to death while the earth is half covered in atmospheric ash for a year. The slow Thanos snap.

            the lagrange point isn’t a stable orbit.

            That’s totally true, but to be fair, it’s still more stable and requires less maneuvering than low earth orbit. So if we’re comparing the two orbits…

            I gotta be honest, that sounds like a less-than-optimal solution. But I like that you’re thinking outside the box!

              Lol. Thanks.

              Low earth orbit is consistently unsstable but the drag and gravity is pretty consistent so you’re guaranteed to have to consistently adjust away from earth and speed up, or go the starlink route and just plan on launching a satellite replacement every 5 years(they do still have thrusters and adjust to stay in the right areas for their lifespan).

              The lagrange point actually has a wobble to it. Due to solar radiation and gravity from other planets as they move around, so that sweet little perfect spot of neutral gravity moves around in distance between the sun and the earth all the time.

              We’d probably have an easier time covering like 5% of our planet in mirrors spread out all over the place. That would cool the planet down by about 2c. Good luck keeping them all clean.

          any such object placed there would need to have a diameter larger than that of the moon

          Well that’s kind of my point, that’s still a lot smaller than what Elon is suggesting. Elon suggested a sphere with a diameter larger than the earth, if the alternative is a disk larger than the moon, well that actually seems like a much better deal. Also, assuming a disk and a sphere have an equal diameter, the sphere has 4 times the surface area, so that’s not a trivial difference.

          Lofting something that massive up there and more importantly keeping it there given that it’d also be well within the gravitational influence of the moon would be quite the challenge.

          That’s interesting. Yeah that could be a challenge. Given the size of the thing, it seems like the obvious thing would be to utilize solar wind for maneuvering, as it’s already essentially a solar sail.

          The Japanese space agency tested a solar sail in orbit with a novel steering system, rather than changing shape, it used something much like LCD cells to shutter individual quadrants of the sail. Something like that could potentially work.

          Point two is that the Deep Space Climate Observatory is currently already parked there.

          Yeah, that’s a good point. Although if you were actually building something this big out there, you would probably build in some capacity for probes to dock to it. This is a huge installation after all, a facility more than a probe. Or just add on a module that duplicates the capabilities of the deep space climate observatory. I mean once you’re constructing something this massive, that additional cost has gotta be a drop in the bucket, right?

    We already have the answer of how to deal with this:

    We can and have shut this thing down when the political will is available. The efficiencies developed in agriculture and manufacturing have shown that the vast majority of economic activity is effectively idle, not necessary, and purely for the purpose of creating the impression of larger economies than are actually present.

    No one starved due to lock-downs. No governments collapsed. Netflix views increased. People took on hobbies and got more exercise.

    We have an exact template of what we would need to do to save our climate future.

    All that we lack is the political will. And no, geoengineering solutions to prop up and support a broken approach to economics isn’t a solution.

      While I agree that we have the technology to wildly decreas emissions by just cutting down on inefficient production, I do want to point out people did infact starve due to covid/lockdowns. Many lost jobs, big corps took the opportunity to run mom and pop shops out of buissness, prices skyrocketed. My family wen’t from scrapping by to relying on food drives

      It cost governments around the world trillions of dollars to get through COVID… The uk’s debt went from 80% of GDP to 100% in the space of just 18 months. It’s hardly a viable economic plan to carry out on an ongoing basis.

      Many non essential industries and travel just completely froze And guess what? Co2 production barely even stuttered according to your graph.

      The solution is to transition into a renewable, prosperous, circular economy. Not go backwards into poverty.

      No one starved due to lock-downs.

      Not true, the pandemic caused major inflation, doing the same for a prolonged period of time would be devastating.
      But there are ways we can cut CO2 without increasing inflation. Like make the use of private jets illegal.
      USA could cut their CO2 in half by following the model Denmark has developed since the 70’s.
      Denmark has higher industrial and agricultural production than USA, and has more data centers per capita than USA, yet we only release half the CO2 per capita. And that’s without using nuclear!

    We need to stop letting supervillains pollute the sky with garbage. As well as a moratorium against satellite quantity, and satellites that serve any purpose outside of science and some communication. (Starlink should be deorbited as well, if for no other reason than the atmospheric pollution created by the short life cycle of those satellites.)

    He’s cooked, pack it in. If we’re lucky he’ll fall in love with an AI pigeon and live out the rest of his days in squalor, which is the only part of Nicola Tesla’s legacy he deserves.
