Because this is HN, (in Allo Allo's Michelle Dubois voice...) "I shall say this only wonce": If you're curious, have a look at Earth's historical temperature and co2 data going back millions of years. What you'll notice is that there's always been oscillations, like a more or less predictable wave. Human activity is polluting the Earth, yes, but this fixation on co2 and other gases (cow farts, really?) is unhealthy to put it mildly.
I'd like to see the same attention being given to plastics (so much single-use crap and how much of it can be recycled?), synthetic clothing, and all kinds of other chemicals including the ones we put in ourselves (pharma, food) and the environment, like fertilizers or the byproducts of mining today's fashionable minerals like lithium. Not to mention the explosion in electromagnetic frequencies activity, which somehow is taken as normal and ok by the same scientific establishment which accepts thousands(?) of fake papers every year for publication. You just have to love the irony when something like Science is deemed 'settled'-- in that regard, it's almost as if we went back a few centuries.
There's certainly a lot to be said for humans needing to take better care of the planet. Co2 just gets a little too much attention for my taste. And don't take from this that I love oil. I find fracking to be abominable and another big factor in polluting the land and the water tables.
