"What objections could there possibly be to this large-scale atomic harbor-blasting project?"

That was a question asked in the 1950s, when nuclear scientists were hot to apply their expertise to peacetime projects. David Roberts reminds us of that insanity in the context of reviewing Jeff Goodell's new book "How to Cool the Planet" ? which has some geo-engineering ideas to sell:

Geo-engineering ideas are all over the map, and quite a few are just wacky -- say, shooting a nuke at the moon to kick up a cloud of sun-blocking dust -- but two basic ideas are being taken seriously.
The first is what the British Royal Society has termed "solar radiation management," sometimes known as "solar shielding" ... [by] shooting sulfur particles into the upper atmosphere to imitate the shading effect of a volcanic explosion... [or] brightening the tops of clouds to make them more reflective, thus deflecting more sun, which can allegedly be done by injecting them with super-fine water droplets...

The other frequently discussed form of geoengineering... is pulling carbon dioxide directly out of the air...

Are these really like those crazy nuke things from the 50s? I'd worry about over-cooling by accident. How could one possibly set the right temperature? And if we could, maybe it would only get worse:

If humanity takes control of the climate, do its existing inequities become a collective moral responsibility? After all, even the pre-industrial climate was, in some sense, unfair -- some areas too hot, too arid, too wet, or too cold, life harder for some than for others. Do we try to restore an old climate or create a new one, and who decides which is better? If history is any guide, it will be the wealthy with their hands on the levers. Climate imperialism, anyone?

We could have all sorts of fights in the atmosphere, a dramatically huge version of the squabbles people who live in the same house when one after another adjusts the thermostat.
