And yet, we're not completely stuck. It is absolutely clear that not enough has been done to reduce our carbon emissions, and we're on a bad path on track to ~2.5°C warming in the next century. However, something has been done, and if nothing had been done we could easily be on track to >4°C global warming. That would be much worse.

So, how did we achieve what little we have? Well, because many people have cared, and have made the right decisions. Not enough people, or maybe not good-enough decisions, but some people, and somewhat good decisions.

So, what were the decisions which brought us down from an apocalyptic +4°C to a very bad 2.5°C path? Was it enough consumers making environmentally conscious choices, even if they were less convenient or more expensive. No. It was enough voters wanting their leaders to do something, even if it wasn't quite enough, but it was something. And something isn't nothing.

We will never have enough people voting with their wallet to fight climate change, because our rational understanding of the big-picture cannot overpower our intuitive day-to-day choices. However, we may have enough people voting with their ballot to fight climate change, because the rational big-picture can, sometimes, decide whom we vote for.

are you sure we aren't on the >4°C path?

AI could very well put us back on it.

Considering that current energy usage of AI is very likely to plummet in the coming years due to efficiency gains (which we've seem massive improvements on in the last couple years) and most of these large companies building datacenters are looking for and investing in specifically clean energy sources (nuclear) I don't think AI is a meaningful contributor compared to all the other high causes of global emissions.

AI which helps us design a commerciallizable fusion reactor might buy us a century.
