Scientists Unveil High-Res Map of US Carbon Footprint
From Wired online:
A team of scientists has completed a carbon dioxide emissions inventory of the United States plotted down to 100-square-kilometer chunks.
That means that the NASA- and Department of Energy-funded scientists can detail emissions across all 9 million square kilometers that compose the United States. For a full explanation, check out the video that Purdue's Kevin Gurney put together, which features a number of other excellent CO2 visualizations. Andy Revkin, the New York Times' environment-beat writer, put a memorable headline on a post about the video, calling it, "Breath of a Nation."
The work, known as The Vulcan Project, has already yielded a significant discovery: Previous CO2 estimates that used population as a proxy for emissions overestimated the Northeast's greenhouse-gas generation, while underestimating the coal-heavy Southeast's contribution.
