Individuals who can do things that will change the behavior of others through positive reinforcement can change things or by going to work at a company that was started with one of those efforts in mind. For example one of the biggest impact things an individual could do right now for climate change is to figure out a way to make a concrete that’s cheaper than concrete but not made in the method that releases CO2 and start a business out of it.

My only point was about _collective_ behavior change that is often advertised as a way to stop climate change that is advertised by many. I think that’s completely pointless and impossible. For example I do nothing to conserve anything in my day to day actions other than not wasting money or time. So if you can make CO2 reduction possibly simply by saving money and time then it’ll happen automatically.

Also I’m not so pessimistic about the current direction as you. We’re headed for a 3 degrees C change in temperature which isn’t going to have the most disastrous impacts that could have happened. There’s still also a lot of emerging tech that could play out and reduce those predictions further.
