And it's not like you have to put the full effort in, Mother Nature will do a lot of the rest if you just push the boulder a bit to get it rolling. Humans are not the only cause of climate change, they simply were the catalyst to get it going. Which also means that if we did the unthinkable and stopped all emissions now and forever, the boulder is still rolling down the hill now. It's why Net Zero(TM) is just greenwashing and not some solution.
