Once you start engineering Earth's climate you can't stop

I like adding iron to the oceans far more (assuming it works, which is less clear) than sulfur dioxide spraying, since it doesn't result in acid rain. However, given the options of massive global climate change and geoengineering, I know which I want. Yes, any form of geoengineering will cause problems, but not doing it looks to be far worse. The world is headed for sustainable carbon neutral fuels, but we're not going to get there in time to prevent a fairly large temperature rise, unless we use geoengineering.

Yeah, I'm more comfortable with iron in the oceans than sulphur dioxide in the air. If only for the side benefit that it seems like oceanic iron might provide a food boost for creatures that I like. My other favourite is massive, deep-sea robot assisted kelp farming.

I'm not convinced that we are going to be too late with renewable energy. Or rather, that we are already too late. I think it is likely that we will be too late but I don't think it's a write off quite yet.

I thought something like "yes, we definitely need to be fully briefed on the risks of riding the tiger, but I want to be clear *how much* worse they are than standing around in front of the tiger not getting on, and if we can survive that."
