Not sure that's really the case. Carbon capture and sequestration is a thing, and is something we know that we can do with current technology. This atmosphere modification plan is still entirely theoretical, and any scientist who believes they can actually model all potential consequences is a quack, at best.

Certainly carbon capture won't be enough; we do need to reduce emissions. We have the technology to do that, but often not the political will. I don't know how to fix that. Fortunately the move toward renewable sources of electricity does continue to march on, just a lot slower than it needs to be.

What if the unintended side effects are worse than the effects of climate change?
