Yeah, that's definitely not consensus. Even I am not saying that's how it is. The consensus, however, on this is 'we don't know', but the possibility definitely remains that we have already passed the point of no return. Do I think we have? I have no clue. Does it matter? Not really, actually.

My analysis has so much to do with speculated future emissions. It is widely believed that there exists a point of no return, but where that is and exactly how far that goes, nobody knows. However, historical data gives us ample reason to believe that it could take us to a temperature where mammals did poorly, and where the planet is a dramatically different place.

Will this kill the planet? No. Not even close. The planet aint gonna die until the sun engulfs it in 5 billion years or if it collides with another planet. Will all life die? No, lots of life will survive as lots of life has survived throughout many massive warming and cooling and extinction events throughout prehistory. But could we turn the earth into a place not suitable for humans? Yes. We actually do not know exactly how unsuitable though.

But you already know all this I'm sure
