Who is making any assumptions? I simply said:

>Meanwhile, US CO2 emissions peaked in 2007 and are down 20%, which is Franky astounding. Global CO2 emissions is predicted to peak this year or next, although a retrospective analysis may show that it already peaked earlier in 2016 or 2018.

The historic data is fact. The trend may or may not continue. Slope may increase again, hold static, or keep decreasing.

Im not saying everything is sunshine and puppies. for example, it seems that the slope of methane is still increasing.

oh I agree on the facts, I disagree on the significance you give them. It is not astounding, it is something which happened multiple times already. Secondly, I disagree on the prediction you mention.l (I would nonetheless new interested in a link on the latter, I am genuinely in search of good news, even if I'm aware I do not necessarily sound like it...)

On track for a new record this year though...
