What is the gravamen of the issue of global climate change?

What is the gravamen of the issue of global climate change? To address the issue, one ought to point out a simple truth, to begin with:

That so serious is the baleful influence, of the climate-change-deniers, in Global North politics, today, that one must drop all pretence, at civility, in pointing out the stupidity, which the ecocidal environmental positions adopted by the Ron DeSantises, and their ilk, in U.S. politics - who pretend that what is, isn't - represents.

Truth be told, it is actually we humans, who are at risk of becoming extinct, if we make our planet uninhabitable for our species. Let's be clear about that - for, if it isn't halted, ultimately, continuously trashing the natural environment, in egregious fashion, in pursuit of endless profits, will doom humanity, not the planet Earth.

We must all, also bear in mind, that long after our extinction, the planet Earth will recover, in a few million years, hence, and thrive - without shortsighted, foolish and greedy humans: barring it being smashed into smithereens from an object from outer space, before the end of time. That is what is the gravamen, of the issue of global climate change, oooo, folks. Full stop. Case closed. Yooooooo...
