You know what happens to soil when it rains salt from the clouds, right? Sulphur at least is more natural, as it's also released by volcanoes. https://extension.psu.edu/sulfur-fertility-management-for-grain-and-forage-crops https://extension.psu.edu/sulfur-fertility-management-for-gr...

    Or consider the year without summer: https://en.m.wikipedia.org/wiki/Year_Without_a_Summer https://en.m.wikipedia.org/wiki/Year_Without_a_Summer

      Just remember a year without a summer means a year without most agriculture

    And ozone for that matter

  We can do it over oceans where the impact should be limited.

  But we just got rid of acid rain? That was going to eat us and the Colosseum alive back in the day.

  The salt water comes from the ocean and goes back to the ocean. I'm not sure what to take from the natural comment or if it's serious... Natural things can be profoundly bad for the earth and things that live on it, like poison... Or volcanos... Also salt water, incredibly natural it turns out.

    Salt water = natural. Salt rain ≄ natural. Salting agriculturaly viable soil is not good at all. https://en.wikipedia.org/wiki/Soil_salinity https://en.wikipedia.org/wiki/Soil_salinity https://en.wikipedia.org/wiki/Salting_the_earth https://en.wikipedia.org/wiki/Salting_the_earth Agreed, being natural is not necessariliy good. Solar flare, hurricanes, typhoons, tornadoes, eathquakes, polar ice cap and glaciers melting are all natural phenomena. Mabye they're good for the planet but not good at all for the puny earthlings, us. Also, "we'll just do it over the oceans where impact should be limited" is risk prone, just like controlled burns.

Am I understanding that page correctly? Sounds like 3–4 deg C of cooling for an estimated $5 bn/yr.

  Yeah, if climate change really was an “emergency”, mitigation would be extremely cheap. With big side effects. Nevertheless if it really were an emergency… in real emergencies, triage happens, and downsides are taken for granted. Thankful that there’s no real emergency yet, but I suspect governments will drag their feet long enough that there will eventually be one, and then emergency relief will be deployed anyway, but it will cost way way more than 5bn.

    We are in an emergency, look at those graphs ? Imo governments know this , just not yet sure what to do yet.

    I don’t know. My province in Canada is experiencing anomalous weather events year after year, and while things still look “okay” we seem to be encroaching on visible threshold events quite rapidly. Sure, these events could mysteriously stop. Or stay very much the same, acting like a new normal that isn’t so destructive as to be an emergency. But the trend line is there. Fires increasing, biodiversity decreasing, floods occurring more dramatically and frequently, 100 year events predicted to be 10 year events not in decades but right now. If that’s not an emergency, what is? If you’re thinking something like “when the province is stricken with drought for 10 years and everyone’s starving”, I hate to tell you but that’s well past the emergency date. At that point, you’re already done and the initial emergency happened.
