For myself I figured that there is absolutely nothing you can do for climate working as a software engineer. The best thing you can do is to become politically active. Go join some environmental movement you sympathize with the most. The next best thing you can do is make money at whatever job you can get and donate a significant amount to the aforementioned movement. I know this answer is not very popular among the techies, but I am afraid it's true.
Have you opened this thread? There are nearly 200 comments, some more concrete than others but still, do none of them sound like a software developer could do it?
