As part of the ongoing, comprehensive coverage that the “Financial Times” has been devoting to the issue of climate change, including of the Copenhagen conference, here is a truly terrific and most informative interactive graphic depicting several levels of how carbon dioxide emissions are calculated, by country total and per capita, by individual year and cumulatively, and with and without emissions attributable to land-use changes. (Remember to note, though, that carbon dioxide is the biggest part of the problem, but not the only part. See my graphic recently posted here.)
