The only thing changing slower than expected is humans. We resist stopping digging and burning fossil fuels.
One thing we know reduces emissions and pollution: stop digging and burning fossil fuels. We're using every excuse not to. Everyone has their thing they want to do that delays capping the wells and closing the mines. Beyond overconsumption, we can't even talk about overpopulation without losing our shit (though a few people and nations have made great progress, see Mechai Viravaidya, for example).
