Most of the discussion of combatting climate change focuses on reducing atmospheric CO2, but there's an entire second category of approaches: Solar Radiation Management, some of which could be much faster and cheaper than reducing CO2. https://en.wikipedia.org/wiki/Solar_radiation_management

While reducing CO2 emissions via investment in renewables is still an important long term goal, if we're already heading towards a potentially catastrophic situation, it seems we should be investigating other forms of climate engineering more seriously?

I find some challenges in geo engineering: - Problem shifting. Gaia is a very complex system, and geoengineering solutions can have unexpected effects - We don't just have the problem of climate change to solve. Loss of biodiversity, acidification of the oceans, soil loss have to be taken into account. - We have the jevons paradox. By finding a technical solution to the problem we can think that it is justifiable to continue polluting.

If we could slow down human activity, nature would begin to regenerate. I think it is possible to slow down our development without any major problems for humanity, after all we have never lived in a period of such prosperity. It would be a matter of maintaining our level of wealth (or even lowering it a little) instead of aspiring to more.

Solutions created by us are usually fragile compared to natural systems that are anti-fragile.
