    I think the biggest takeaway from this video is the idea of termination shock.

    What happens if we’re happily chugging away doing stratosphere aerosol injection with all our fancy technology and a one-in-10,000-year solar flare hits us dead on and takes out the global power grid? Scary thought on its own, even scarier if our technology is keeping us from roasting.

    There are so many reasons that we might need to cease applying our mitigations.

    A very interesting video on geoengineering, a apparently not-that-fictional idea to (ideally temporarily) hold back climate change until we (ideally) cut the problem at the source.

    One of the things I'm wondering about is how is geoengineering horrific? It's certainly a bandaid instead of a real fix but I don't feel it is really horrific if not mismanaged. I guess it's just that by virtue of affecting Earth's climate, it's incredibly risky and can be horrific if mismanaged.

    There's also the risk of people thinking this is literally chemtrails and, as mentioned into the video, people thinking this is not so temporary and deciding to use this as a kind of giant global thermostat (or, given the word global, trying to tune it how each country's ruling government want it and destroying everything.)

      Where you mentioned mismanagement, we’re in this situation precisely due to our markets mismanaging the earth’s resources. It’s possible for the response to be accordingly mismanaged depending on the structure of systems that deploy the efforts.

      Also the assumption that we know all or most of the potential consequences of something that will interact with the nearly incomprehensible complexity of the world’s ecosystems seems hopeful at best. Assuming we know all the risks today, it’s possible that things do not proceed the way we expect. Modification of the climate at such a scale in a unilateral way could accelerate preexisting damage or create new sources of damage.

      I only mention these notes to offer another perspective, I believe there is room for these kinds of approaches, however with informed caution.
