We are (very likely) already past the point of no return when it comes to tipping points. You can’t refreeze the arctic which is currently thawing at alarming rates. You cant grab the methane back from the air and put it into the ground.
The release of methane and other ancient CO2 from the permafrost will catapult us past other tipping points like a BOE as well.
It’s not fatalistic, it’s realistic. The IPCC has warned of this stuff for years and people still believe renewables are going to allow us to skirt the worst of climate change when it’s already locked in lol.
