Someone's bound to hack the atmosphere to cool the planet. So we urgently need more research on the consequences.
going to do it at this point, actually, because it's so inexpensive. Already the impacts of climate change are looking to be so disruptive that I don't see in this world how such a low-expense solution doesn't get implemented by someone. There's just nothing else in the world that can cool the planet as quickly. Even if we started rapidly decarbonizing and, it's still a decade timescale for consequences. Whereas blocking sunlight, the climate response starts right away.
The technology's not so complicated that we would need just the person who developed the technology to be the one to keep doing it. And so I'm a little skeptical about that argument being the biggest issue, because we already basically know how to do it. It's within the grasp of a medium-sized country or something. The resources are substantial enough that it would be hard for a single individual, or a very small country to do it.
KR: There might be some technical experts, like me or other people who have worked on this, that would say: ‘Yes, I've seen enough to believe it.’ But in order to have collective decision-making at the global scale, you need science that's viewed as legitimate by everyone. NotBut that's why we need more research. And we need more diversity of who's doing research and where, because the results are going to need to be viewed as legitimate by a much broader group of people.
