All of these ideas involve depositing the heat elsewhere on the planet, or even keeping in the same spot. That's not going to be great. There's only one solution: stop the greenhouse effect at the origin.

Reflecting heat back to space should also work. E.g. cover large areas with white (IR-reflective) layer. Or with clouds. It's pretty involved, and harder to pull off exactly as planned, but should work in a pinch, e.g. to stop a catastrophic runaway heating trend.

  These idea kill two birds with one stone: they stop global warming, and solve the threat to fossil fuel companies from cheap solar energy.

    Oh fantastic! Any way we could maybe just solve the second problem to get it done faster? Those poor fossil fuels companies are really hurting-- honestly that should be our priority. We can't have oil execs going hungry. /s

    Depends on the material of the cloud. Fire up some volcanoes! https://www.usgs.gov/faqs/do-volcanoes-affect-weather https://www.usgs.gov/faqs/do-volcanoes-affect-weather

  First: ice is a great reflector. Second: you'd have to cover large areas, with unknown consequences.

The Earth radiates an enormous amount of heat away into space(in fact the same amount that it receives from the sun), so all we really have to figure out (for a quick fix) is how to tip the balance negative enough to offset the additional warming from greenhouse gases. Long term we need to stop the greenhouse effect, but things are getting dire way faster than even the most delusional optimist could forecast reversing emissions.

  So we should bring back CFCs and destroy the ozone layer?
  - Workaccount2 2y ago
    Well no, in the same way we shouldn't bring back asbestos to fireproof buildings. There are other techniques, none without downsides, but not doing anything has a pretty enormous downside.
