That is a map of fossil fuel fluxes, or where CO2 is being emitted.
Observe how the hot spots correspond to major, usually overdeveloped world, cities, mostly in the northern hemisphere, and around major shipping and airline routes.
Note also the hot spots in China and India, where they are still heavily reliant on coal, and the shipping lanes heading for Europe (through the Suez canal) and North America, where many of the consumer goods, especially from China, end up.
Atmospheric CO2 is fairly well mixed, although with sufficient variation that there are many monitoring stations around the world: these are then averaged to give the mean level of CO2 in the atmosphere. Some remote sensors, such as the one at Mauna Loa in Hawaii are considered better gauges than others. You can keep an eye on global CO2 levels here: https://www.co2.earth/
Pre-industrial levels of CO2 were around 280 parts per million. 350ppm is generally considered the upper end of the safe range: https://arxiv.org/ftp/arxiv/papers/0804/0804.1126.pdf. We are on course for 450ppm or worse.

I wonder what's producing carbon up in the arctic? There seems to be some spots north of Greenland.
We've gotta get close enough to that helmet to pull the choke on it's engine and flood his mind! Or, we could just read this tiny ad:
