This question pops up quite regularly on HN. I am always giving the same answer. We, HN crowd, presented with a problem tend to reach for a technical solution. Unfortunately, climate change is not an engineering problem, it's a political problem. IT will not solve it. The best we, as engineers, can do is the same as for anyone else - step out of our comport zone and join a climate movement. Extinction Rebellion is my…
The technical problem should be (roughly), how can we continue to enjoy our lives and the standard of living we have achieved, and continue to bring more of the world to that level, in a way that is sustainable long term. There are lots of promising routes to making this happen, and we have already seen lots of progress towards reducing environmental impact.
But there are people that want to move backwards, to reduce our standard of living, to reduce our freedom to make our own choices, and to enforce some kind of forced mediocrity that will help ration our natural resources. I reject this (and weaker versions of it) and believe there is more to be gained by focusing on progress than on telling people what to do.
