Interesting that there are large hot spots in jungles and undeveloped areas, even a couple large ones in the ocean. No doubt straight white males will be blamed for them somehow.
South America,Central Africa,SE Asia: Could be jungle being cleared.
China: That would be the industrial output that is conspicuously absent from the US and Europe.
Also apparent are the higher concentrations over South America and southern Africa. These are likely the result of biomass burning in these regions.
Notice the oh so scientific word "Likely". They love to inject unproven conjecture giving the light blanket of possibility without going out on a limb.
