The issue is that this graph might give a wrong idea..

For example, it shows that now in total upper-middle income people consume more CO2 than upper income ones.. but what does that mean?

If there is just 10 guys in the upper group, and 100k in the upper-middle one, is a very different story than if they are the same size
