If governments wait too long some rogue organizations might start geoengineering efforts. A few orbiting Mylar shields are in order.

I know we're all really dedicated to solving social problems with far fetched technology but this is a lot even for here, come on.

  At some point it's either going to be using tech to try to directly solve the issue or accept dying and people will never take dying as an option, regardless of the morals behind the other option.

    Somehow I doubt those are the only two options.

      It's almost like we need to decouple from the tech and media induced buying spree that is propped up on manufactured obsolescence. That we need sweeping reform and people need to take going Vegan (or at least cutting down meat consumption) more seriously. Air travel should not be subsidized until we have cleaner means of transport, and above all we need to return the buck back to Corporations who green washed us into ownership of their messes. Finally, we also need to be very critical about carbon credits, or emissions offsetting, which can be (and have been) incredibly corrupt. I'm also aware that this platform isn't going to look favourably on "tech slow down", as it is very hard to want to slow down or turn off the faucet.

      Personally I doubt that there's any other one, the impact of climate change seemed widely underestimated and the recent large spike of emissions has yet to have any effect. There's already way too much emissions already "locked-in". We are already having "once in a lifetime" events every month.

  The first well-done climate models by Manabe and Wethereld in 1975 found that a 2% reduction in solar radiation would cancel the effect of a doubling in atmospheric CO2 levels.[0,1] This problem has an engineering solution that should be implemented as soon as possible.

    When I see stuff like this I think immediately of like, the Four Pests Campaign, kudzu in the US south, Australian erosion caused by rabbits etc. We can't even reliably predict or manage the consequences of our actions across a single ecosystem. Mind boggling to me that we still however have high confidence in our ability to.

        A 2% reduction in insolation is consistent with solar cycle variations. Aerosols are not the way to do it because they are not reversible, but a shield at L1 is.
