- "Especially since that reduction in temperature was only temporary."
It still seems a useful tool to have in reserve, if you later decide you want to halt a runaway feedback loop linked to temperature. E.g. an albedo feedback from melting sea ice [0], or methane clathrates thawing from a warming ocean [1]. Temporary changes can leave permanent effects.
It'd be nice to R&D this stuff sooner, and not really need it, then delay and debate and suddenly there's a black-swan planetary apocalypse and the one tool you need right now isn't available.
