"No one sensible is saying humans can't adapt to climate change, it's just whether that adaptation is going to lead to a significant degradation in quality of life compared to making changes now to reduce the impact."
The trouble is that a lot fo the green movement, especially the modern "woke" authoritarian corporate-backed iteration of this movement, is in the habit of planning solutions which would quite possibly be worse than the worst likely scenario that climate change could cause (which is a fairly bad scenario). We need to end our addiction to oil/gas/coal, if for no other reason than that they will run out sooner or later and right now make the world dependent on fuel supplies from all manner of awful regimes in unstable countries, but the "greens" who want to wipe out fossil fuels before we've had a chance to replace them, want to end farming and have us all on diets of ultra-processed bugs, and want things like individual carbon credit surveillance and rationing schemes, are quite likely more dangerous to standards of living than climate change is. There is a right way to fix the climate issue, that is nuclear power, hydrogen road transport, non-CO2 emitting industrial process for steel and concrete production, and investing all spare money in to development of technologies which can provide direct equivalents to current fossil fuels, but many in the curent green movement seem so devoted to an anti-capitalist anti-freedom anti-modernity agenda that it is as if they don't want a simple fix or the climate because then they'd have no way remaining to push their ideology. Climate change is an industrial problem, to be fixed by replacing, a soon as practical, CO2 emitting technologies with non-emitting alternatives of comparable performance, but today's "green" movement dismisses that proper form of solution because it wouldn't require massive disruption to lifestyles, and their corporate backers support them because the corporate backers would rather cause massive societal upheaval than sacrifice profits for a little while whilst swapping out dirty technologies for clean ones, under the present "green" movement's thought patterns mass emissions would stay busienss as usual for the big corporations, its only the little people who would have changes forced on them. Get talking to many of the current generation of "green" activists and you'll find that given the choice between saving the planet with some "magic bullet"* technology or ending capitalism, they openly admit they'd opt for the latter.
*good news, perhaps too good to be true, but it even looks now like there migh be natural hydrogen reserves ("white hydrogen") which can be extracted from the ground, hard to believe given hydrogen's propensity to react with anything it can, but the evidence seems to be there, could help us get used to hydrogen for mobile applications while we get enough nuclear power online to run huge electrolysis plants, infact some suggest the hydrogen is being constantly replenished by geologial processes so could be a long term fuel in itself.
