You are right. The world was closed for business in 2020 and emissions were down only 7 %. We need to lower emissions by more than 7 % every year but you can only close everything once. Quite baffling that even on HN of all places, where people propose technical solutions for everything, behavioral change is seen as the only way to combat climate change.

No. Climate change is an engineering problem and technology is the solution.

I'm guessing within the next 10 years the non-sponsored "evil scientist" style geoengineering experiments are going to start. When someone builds the first balloon-floated tube to put particles in the upper atmosphere the world is going to freak out and it's going to be so cool to see what happens.

I don't think there is a lot of people who think behavioral change is the only way to combat climate change. I think it is the "minimal way" to combat it, it is necessary but unfortunately not enough. If we do not change this "always more, don't care for the externalities" mentality, even if we find a solution for global warming, we will hit other planetary limits soon enough.

I'm not the only one who agrees - Elon Musk is offering 100M in prizes for carbon removal solutions: https://www.xprize.org/prizes/elonmusk

Adaption seems more realistic from an engineering, political, and game theory perspective.
