A really powerful visualization of US data on CO2 emissions has been released for viewing in Google Earth. The data came from Project Vulcan, produced by a team of scientists lead by Dr Kevin Gurney, an assistant professor of Earth and atmospheric sciences at Purdue University. Vulcan data represent detailed emissions for all 50 US states in 2002. Since the results were publicly available, a Googler named Simon Ilyushchenko decided he could produce a good visualization using Google Earth. I like the fact that the data is available either as a fully powered KML file 
for Google Earth, or on a web page using the GE Plugin. For a quick narrated overview of what the data looks like, watch this YouTube video:
