    this seems incredible to me. especially given the co2 emission-equivalency with the deforestation of the amazon. i haven’t clicked the link, but do you know whether that calculation takes deforestation into account?

      Yeah, deforestation is a much smaller impact thing at this point than fossil fuels. Big enough to matter, but only a bit of the overall problem.

      Per the IPCC:

      Based on multiple lines of evidence using interhemispheric gradients of CO2 concentrations, isotopes, and inventory data, it is unequivocal that the growth in CO2 in the atmosphere since 1750 (see Section TS.2.2) is due to the direct emissions from human activities. The combustion of fossil fuels and land-use change for the period 1750–2019 resulted in the release of 700 ± 75 PgC (likely range, 1 PgC = 1015 g of carbon) to the atmosphere, of which about 41% ± 11% remains in the atmosphere today (high confidence). Of the total anthropogenic CO2 emissions, the combustion of fossil fuels was responsible for about 64% ± 15%, growing to an 86% ± 14% contribution over the past 10 years. The remainder resulted from land-use change.

      And CO2 is big enough that this means that fossil fuels are the biggest piece of the problem:
