Finding RELEVANT Fault is part of Science
Of course the rate has changed, but that level of precision is irrelevant to this question. If it was a steady change to this level, then it is off by 50% (straight-line-average), which is irrelevant; if it is a hockey-stick curve that only makes the point stronger, i.e., humans are super-rapidly producing that scale of greenhouse gasses.
The entire point is a very rough estimate that humans are outputting greenhouse gasses APPROACHING THE SCALE OF the greatest climate disaster in the 4.5 billion year history of the planet.
Despite the ordinary expectation that the Siberian Traps' gigantic volcanic activity for more than a quarter-million years dwarfs anything humans could ever do in a few centuries, the fact is that the scale of our output is now in the same playing field as that disaster.
I'm pointing out that we do not have a gnat in the room, we have an elephant. Yet you want to argue that I didn't specify Asian vs African elephant.
I'm not trying to weigh the elephant to the gram, I'm pointing out that we need to do something before it tears down the house.
Your comments about the minutiae, whether or not they might be technically correct, are not science; they are a distraction.
Have a good evening. I'm done here.
