How?

Anyway check out my new truck "the gas guzzler 4000"

Absolutely. It's not something new nor caused by something new.

But trump has cut a lot of green laws for data centers. And power plants.

And the sheer amount of additional heat and power consumption these data centers that are running, are using is insane. Akin to adding another few states worth of power and pollution in a span of a few years.

Of course that much additional heat and green house gasses makes a difference. I mean, my understanding is we are probably already past the point of fixing it.

The best we can do is completely stop green house gasses now and hope the extreme consequences only last a few hundred years.

But trump and these data centers are currently undoing all of the progress that has been made (here in the U.S anyway).

Not that much progress was made. But there were corporate interest efforts.

I mean let's be real. The epa regulations were still absurd before Trump cut them, and they never fine anyone even though it sure seems like literally every company has been lying about meeting those restrictions.

Its a millennia long project.

This is another reason why geoengineering is such a bad idea. Even if you stumble onto something that works without killing everyone, you have to consistently do it for many centuries.

Europe (alongside the USA and other countries of the "western world") has been releasing disgusting amounts of climate change-inducing gases since the 18th century, and they (alongside the USA) were the main profiteers of climate pollution until the latter half of the 20th century. Arguably still are, though other countries like China and Brazil also play a part now.

Granted, this treats nations as monoliths, it's not like the population of most countries really had a choice for the most part.
