What’s with this map?
Countries on this map are sized to show their relative CO₂ emissions from energy use from 1850 to 2011. Historical (or “cumulative”) emissions remain relevant because CO₂ can remain in the air for centuries. Europe and the US dominate, having released around half of all the CO₂ ever emitted.
