According to this graph the CO2 had to drop to below todays level for temp to slowly get back to what it is today. ie 3 million years to self-correct. (Well that's just me going on those 2 graphs with mis-matched x axis, What do you make of it?)
It was 280 ppm before the industrial revolution, but a couple of blacksmiths WW1 and WW2 had only raised it to 300ppm. It's risen another 125ppm since I was born. If we do nothing, just carry on as normal it'll rise at least another 125ppm in the next 70 years. That's definitely into the hot zone. In 350 years we'd be back in the +14 C range. When do you think we should start doing something about it?
(Apparently there's heaps of coal to last well beyond 350 years. Not sure about oil but they seem to keep on finding it.)
Another interesting fact, at 700ppm, the concentration of CO2 in a crowded physics 101 lecture theatre for instance, we become drowsy and susceptible to nodding off. That's only 200 years away, can we evolve to remain alert outdoors in 6 or 7 generations?

Not so keen on ev,s no more in the land of net zero.
EVs of course will only make a minor dent in emissions, but as cammd said, actions rather than words. They are an easy no-compromise-to-lifestyle option to demonstrate you are a little concerned about the climate.
As for turning off the aircon!
Net zero is all that'll do it. Volcanoes raised it in the past during times of intense activity. What's intense acticity? Lets say, at a guess, it's 10 times what it is today. Then that is, according to Fangman's googling, 0.26 times 10 = 2.6 gigatonnes per year. China's currently doing 12 gigatonnes pa. So even a small amount above what the natural sinks can pull out will get levels too high, just takes a bit longer.
Yes ours needs very little AC, and it was built in 1952. Big front and rear doors, the Fremantle Doctor blows right through. Only had it on 2 maybe 3 times this summer so far. Cold in winter though, a lot more heating than cooling needed.
Freo Dr is fantastic, but you also need North facing glass for the Winter sun, just how much depends on your thermal mass.
I am intrigued by the use of hypocrisy as a tool in this forum, as It often seems to be a double-edged sword that cuts both ways with ease.
My initial searches for examples found this fella, Jason Isaac in the New York Post. nypost.com/2024/09/22/opinion/climate-week-fantasy-vs-truth-carbon-is-no-enemy/The opinion piece appears to be the framework for the Net Zero opposition. It's written by a Texas oilman in a Rupert Murdoch/News Corp. publication. The researcher cited has been roundly discredited by the scientific community, but that didn't worry Jason, who served it up yet again.
Strewth, Murdoch yet again publishing malarkey to suit his business portfolio! Who saw that coming?
I digress. The best piece of reasoned investigation into the use of hypocrisy as a tool by climate debaters I found was the below research paper. It's rather long and not for anyone who wants a clickbait headline or 30 second sound bite. I think it gives some useful insight into why hypocrisy is a favoured tool, how its deployment serves varied rhetorical and ideological purposes, and how it reflects deeper societal conflicts over responsibility and action in the face of environmental challenges.

Turn the airconditioning up then, what's a couple of decades in the history of the earth.
Ps. regarding crunch time, pretty sure David Attenborough already declared the moment of catastrophe had arrived back in the 2019 bushfires.
