Global Carbon Emissions:

Originally conceived as one of my Myth Buster information graphics for Newsweek's International Edition, a piece on global carbon emissions showing both national and per capita data has found a home in the April issue of the Atlantic Monthly. The image of a footprint is composed of circles sized relative to the carbon emissions of each nation and color coded according to region. In the final version of this information graphic there will be a second footprint of per capita emissions by nations. That will be a very different picture. The leader in per capita emissions is Gibraltar followed by the Virgin Islands. The U.S. drops down to number twelve and China falls way down the list due to its large population. It appears that countries that don't grow or produce much have the largest footprint because they have to import almost everything they need.

TERRA 436: Global Warming from Burning the Future: Coal in America

This week's excerpt from Burning the Future: Coal in America examines the effects of coal on global warming. Coal-burned power plants are the largest CO2 emitters in the United States, and US emissions of carbon represent 25% of the world's contribution to global warming. Is clean coal the answer? Watch and find out!
