Scientific American: The world is hurtling toward greater global warming, thanks to ever-increasing CO2 emissions. Although the U.S. and China emit much more CO2 than other countries do, it is surprising to learn that some very small countries have the highest emissions rates per person (see our graph, here). It is also surprising to learn, however, that a handful of countries have actually lowered their per capita emissions. The plots below reveal these interesting places (blue dots).
