Global emissions in perspective. Does U.S. carbon emissions policy really matter? Or Europe’s? Or that of almost everyone else, except China? Read this story and study the main chart.

The excess carbon that is released seems to have been collected in the soil when the ice sheets were spreading, which is a good subject for other studies.
