Later in my career as a climate modeller, I expect to spend a lot of time studying geoengineering. Given the near-total absence of policy responses to prevent climate change, I think it's very likely that governments will soon start thinking seriously about ways to artificially cool the planet. Who will they come to for advice? The climate modellers.
Some scientists are pre-emptively recognizing this need for knowledge, and beginning to run simulations of geoengineering.
