[QUOTE="eclipsenow, post: 77667107, member: 274355"] This Vox piece summarises Solar Radiation Management in 10 minutes - the pro’s and con’s from experts in May 2023. [MEDIA=youtube]EKPFZPyQurA[/MEDIA] Do we risk over-doing it and hurting global agriculture or even freezing the earth as in “Snowpiercer”? Not at all. Dr David Keith models it and says we could probably cancel HALF our warming - but no more as the side effects start to get dangerous. (Only watch this older piece if you need to hear him say it - the Vox article above is more recent.) [MEDIA=youtube]wdQRPUtVrSc[/MEDIA] Not only that, but we have evidence from nature. The USGS says the 1991 Mount Pinatubo eruption cooled the world 0.5 degrees for 2 years. We survived at least half a degree of cooling and dust in the stratosphere without catastrophic crop loss. Also, it takes time to build the special super-wide wing jets to fly the dust up 20 km. Smith et al 2018 said that back then it would cost about $2.25 billion annually to build 6 super-wide wing jets a year. That’s only 0.02 degrees of cooling every 6 jets. If we adjust for inflation that’s probably $4 billion a year for an extra 6 planes. It takes 15 years just to get to 0.3 degrees of cooling - and that’s not even at Pinatubo levels yet!
