The vast majority of people concerned about climate change think there is some paradise we could have kept if only we hadn't been so "climate-sinful". It's uncomfortable to contemplate that the world is changing uncontrollably around you.
You might be misled because you can find graphs of global average temperate that swing wildly by like 10C-20C. But look at the X axis, it's in hundreds of millions of years. Stretch it out to 100k years and it will look perfectly flat.
And yes there is some climate paradise we could have kept it we hadn't emitted so much CO2. The one where it isn't 50C in Baghdad and Europe isn't a dust bowl. Could we have kept it for 100 million years? Maybe not! But nobody is saying that. We could have kept it for 100k years, instead of like 100.
It's comforting to imagine it isn't a problem - both from an "I'm smarter than everyone else" perspective and "I don't have to worry about it", but you're lying to yourself. I dunno lots of people are happy to lie to themselves (at least 50% of religious people I reckon) but I can't do it.
