In the case that there was some earth wobble that caused more solar radiation, should we just allow the climate to naturally get hotter? Or should we involve ourselves in the natural feedback loops to try to keep things temperate for ourselves and existing ecosystems? This isn’t a rhetorical question.
Solar geoengineering is not just a way to avoid polluting. It is a way to improve our dynamic stability.
Reducing the impact of the extinction event we are causing doesn't seem like hubris to me.
There are no mechanisms preventing humanity from having this authority. We will do it, just as we have done it.
It's not hubris, it's just reality. The "how dare we" argument is a waste of time and will not stop it.
If you've cornered someone in an alleyway, you have overpowered them, there are no police or bystanders to physically interfere, and "the law" isn't going to manifest as Captain America and beat you like a mook in some comic strip. You would get away with what society calls a crime. Nothing is stopping you from robbing that person. Do you have the authority to?
It’s happened many, many times before. (The climate change, that is!)
