"To get a sense of how ridiculous carbon pollution has become, going back in time gives some perspective. So, let’s time-travel. The World Resources Institute just updated its compendium of historical carbon dioxide emissions for each country in the world to include 2011. More interestingly, the group has extended the oldest data. Previously the collection reached only to 1990, but now it goes all the way back to 1850."
