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. [2]

- giraffe_lady 3y agoWhen 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.

- westcort 3y agoA 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.
