Only you have claimed that. Particularly "if we don't revert to a 19th century life". You're just a ******* liar and a jerkoff.
And you are a predictably angry and butt hurt victim of facts.
What will the world look like when the use of fossil fuels is severely curbed or abandoned altogether? It will look much like life before the turn of the twentieth century and the introduction of the internal combustion engine.
If we follow Thunberg's or AOC's lead air travel will be stopped (except for the elite ruling class, of course) for instance.
The ripple effect of just that one thing alone will have unintended consequences that you can't even imagine mostly because you seem so stupid but also because the mania to attack greenhouse gases is like a modern day witch hunt. But I can't even take offense at such a childish temper tantrum.
It's well beneath me. And your i.d. is well appreciated. A blending of anger and idiocy.
