it went from 280 ppm to 410 ppm, but I don't see how that proves that there was no natural component in the warming.
For information, here is the curve of the rate of warming (not temperature but its variation / year,) smoothed over 50 years
while CO2 has only increased steadily: the rate of warming was almost the same in the first half of the 50th century as it is now, then it almost canceled out between 70 and XNUMX, then increased again
If there is no natural component added to the CO2, how do you explain that?

here again I would like to know how to explain this graph if it is only the CO2 which intervenes.
And no, it's wrong to say that 99% of climatologists exclude a natural component of global warming, you will not find any study anywhere that has not shown that.
The real study showed that 97% (not 99%) of the articles that cited a cause of global warming, cited the anthropogenic component, but that absolutely does not mean the same thing.
