“People have to get their heads away from thinking about whether they like solar geoengineering or not, whether they think it should be done or not. They have to understand that we don’t get to decide. The United States doesn’t get to decide. You’re a world leader and there’s a technology that could take the pain and suffering away, or take some of it away. You’ve got to be really tempted. I’m not saying they’ll do it tomorrow. I feel like we might have thirty years. The highest priority for scientists is to figure out all the different ways this could go wrong.”
