I don't know if they should be advocating for geoengineering now, but we should definitely start getting used to the idea that we might need it very soon. That means a huge acceleration of research to test the techniques we have, and make sure they don't have unintended consequences (like accidentally destroying the ozone layer.)

> yet the voices to do so are curiously absent

It's easy to think this if you're not paying attention: the issue is very controversial and many people oppose it But a number of scientists signed onto a letter calling for additional research into this [1], and Congress and the White House OSTP are also pushing to speed up and increase research funding [2]. Of course, this kind of research could go away in a single election.
