Someone tagged me on a post on LinkedIn related to a firm that wants to put a common antacid into the oceans to bond with carbon dioxide they’ve absorbed. I nerded out and am deeply skeptical about the entire thing. That’s a pity, as when I dug through geoengineering a few years ago, I concluded a couple of things. One, that if we have to use solar geoengineering — dumping millions of tons of sulfur dioxide into the stratosphere every year to increase reflectivity — we’d have lost the fight for climate action. It’s treating the symptom, not the cause, and the strong support for it by…
