Desperate times call for desperate measures, as the saying goes. As scientists, policymakers and politicians keep one increasingly startled eye on climate change’s ticking clock and the other on the ongoing, upwardly mobile trend in greenhouse gas emissions, it’s no wonder possible solutions that have been long dismissed as fringe slices of science fiction are making their way into the mainstream.

 

Enter center stage geoengineering, a hitherto black sheep of the fight against global warming.

Geoengineering is a broadly encompassing term with a few close etymological cousins—namely climate engineering and climate change mitigation—along with a sizable stable of associated technologies. Some of them, like afforestation and ocean iron fertilization, fall under the umbrella of carbon dioxide removal (CDR) in that they seek to draw down carbon dioxide from the atmosphere. But these are techniques that would in all likelihood shift the climate change needle relatively slowly.
