The prospect of attempting to engineer the world’s climate has become a lot more real since the Paris Agreement.
It’s increasingly likely that at some point, the world’s nations will need to broach the fraught discussion of geoengineering. The UN climate accord was a natural forum to do it.
Yes, we blunt the effects of climate change by getting off fossil fuels. But countries’ most ambitious targets imply use of climate engineering schemes – and that discussion should be done in public.
Blocking the sun by injecting tiny particles in the atmosphere – called solar geoengineering – can lower the Earth’s temperature but has some real costs. Economists run the numbers.
