Here’s what the world looks like if country sizes were proportional to their emissions (world map scaled to fossil-fuel carbon-dioxide emissions in 2002):
And here’s what the world looks like if countries were sized commensurately with the burden of climate change impacts (world map scaled by the World Health Organization’s regional estimates of per capita mortality from late 20th century climate change):
These maps were drawn from the recently released UN Population Fund (UNFPA) ‘State of World Population 2009’ report, which focuses on the theme of women, population and climate change. While the developed countries have contributed the most to human-induced climate change up to now, people in poor countries—most dramatically in Africa—already are much more likely to die as a result of the climate change that occurred up to 2000.
The picture is significantly more skewed if we were to take account of (i) historical emissions; (ii) the unequal burden of future climate impacts.
