My snippet will be a figure rather than text. It shows cumulative per capita emissions (averaged from 1880-2004) on one axis, and population on the other. The area of each rectangle indicates the proportion of responsibility for anthropogenic CO2 forcing to date due to each country. The height of rectangle indicates the average responsibility of the citizens of that country.
This is important. If it's news to you, I recommend you expend some time contemplating it. Click on the image for a sharper picture.
