FWIW, I don't see SRM actually happening, for a variety of reasons, so this is very what-if: but if we get to 2050 and things are, for whatever reason, desperate; then enough countries might be onboard for it to work. In which case, we'll look like idiots if we've done no research.<br /><br />> They don't really come with an abort switch.<br /><br />Actually, stratospheric aerosol does.

Something different?<br /><br />Just to muddy the waters: How? Geoengineering might be cheap, but I don't see how it could be robust. Should we be a global Texas?<br /><br />Could one unlikely event collapse the climate control system?<br /><br />Continually raising alternatives is a great way to never decide.Philhttps://www.blogger.com/profile/07567197089095711546noreply@blogger.comtag:blogger.com,1999:blog-7612793.post-48106734187496283452021-03-30T15:04:26.113+00:002021-03-30T15:04:26.113+00:00There are several geo-engineering ideas floating a...There are several geo-engineering ideas floating around, including iron floating around to stimulate plankton growth, restarting air pollution and increasing the reflectivity of the top side of clouds. Even old fashioned cloud seeding.<br /><br />They all suffer from some real defects. If your country is hell bent on geo-engineering but my country likes the current climate just fine, we might get a little miffed. Also, the threat of overshoot is real but not adequately discussed. They don't really come with an abort switch.<br /><br />Except for space-based solutions, such as blocking sunlight before it gets to earth. (My fanciful imagination pictures a reflective Mylar cloth that not only blocks the sun but focuses the blocked sunlight on a space based power supplier, but that's just my sci-fi background erupting spontaneously.)<br /><br />Most other situations need to be evaluated on not just a cost-benefit curve, but a real threat assessment as well.Tomhttps://www.blogger.com/profile/12747117922597525042noreply@blogger.comtag:blogger.com,1999:blog-7612793.post-36215462713598801382021-03-30T15:03:25.673+00:002021-03-30T15:03:25.673+00:00Questions with answers that will not matter, even ...Questions with answers that will not matter, even if they do.<br /><br />Notice again that economics drives the cheapest.Philhttps://www.blogger.com/profile/07567197089095711546noreply@blogger.comtag:blogger.com,1999:blog-7612793.post-81409827354686151812021-03-30T15:03:18.960+00:002021-03-30T15:03:18.960+00:00I just don't see it being politically feasible...I just don't see it being politically feasible. There's a big difference between countries agreeing to reduce their influence on climate and countries agreeing to deliberately set the global climate to a specific target essentially forever.

Every country in the world will be running their own GCMs to determine what's optimal for them.<br /><br />Also...<br /><br />The US pulls out of Paris?
