Not only is it pants on fire crazy. Most options will almost certainly NOT work. Sequestration, iron seeding, accelerated weathering, and sulfur areosols all suffer from huge scale issues that no one has a serious answer for. I can't keep up with all the crazy ideas, "cloud brightening?", launching 100 MM nanosatellites to dim the sun?, but none of these can scale to the problem. LUCKY FOR US, the problem can be fixed by dramatically lowering emissions. We shall see if we actually come together in time.
