"Global South" doesn't mean literally countries in the Southern hemisphere.
Where? I don't know if your comment had the actual lists of countries in the global north and south previously but it doesn't have it now.
In any case, your analysis is incomplete. It's missing per-capita emissions and cumulative historical emissions.
Of course my "analysis" is incomplete, I wasn't trying to do a complete analysis, just get an idea for where all the carbon emissions come from. Apparently ~2/3 comes from the Global South (currently). Forecasting models don't have normative parameters.
