      There are a bunch of issues:

      • It requires maintaining technical infrastructure for longer than civilizations last
      • It changes the pole-to-equator temperature gradient, altering weather patterns worldwide
      • It changes rainfall distribution in ways that we’re not clear on yet, potentially risking agriculture
      • If we keep on burning fossil fuels but limiting temperature increase with a scheme like this, we still end up with ocean acidification, killing off pretty much everything with hard body parts in the oceans
