Supposedly this impacts crop yields. https://www.theguardian.com/environment/2018/aug/08/reflecting-suns-rays-would-cause-crops-to-fail-scientists-warn https:/

  Yup. Geo-engineering based on solar radiation management (SRM) is probably one of the drastic options we have to try to mitigate climate change effects. That said, the quoted paper's conclusion is that the increase in yields from reduced heating would more or less cancel out the loss in productivity from reduced sunlight. Taking that conclusion at face value, it simply says that there is no net agricultural impact from aerosel based SRM which honestly... is pretty awesome.

  So does global warming. I think such methods to block out sunlight will be the only viable solution. Not because it's better than others, but simply because decision makers seem to have agreed to keep ignoring this problem, in the hopes that when shit hits the fan they are enjoying their retirement. And then the hotfix ideas will be the first to try.

    There is no one magic bullet panacea. Many approaches will be needed to holistically reduce the energy in the water system. CCS and SRM are the leading ones. As far as CCS goes, doing so with mechanical pumps is a waste of energy when biomass can do it much more cheaply, efficiently, and at a larger scale.
