When you say "growth has plateaued" do you mean that year on year increases to our output are now constant? Or do you mean year on year output is now roughly constant?

I realize this distinction between derivative values is further complicated by the even more baseline measure of total accumulation. But I do ask in earnest and don't know the answer.

roughly: 2nd derivative of output is now zero (ish), so the 1st derivative is a positive constant.

Our CO2 emissions are not accelerating, but still increasing.

The CO2 concentration on Mauna Loa is publicly available, here's a picture and a script that fetches the data to plot it:

You can compute emission rates from that data yourself.

See https://ourworldindata.org/co2-emissions. Obviously difficult to determine short/medium-term trends based on the Covid lockdowns.
