Take the next five minutes of your life, and watch this video about a cool new imaging experiment done by Kevin Gurney's research group at Purdue. They've taken pre-existing data about CO2 emissions and plotted it in a dynamic map. The most striking feature is the pulsating nature of the United States' CO2 emissions: we put out a lot during the day, and not so much at night. The maps really show this -- demonstrating yet again the power of images (over description) to convey information.

It's long been my contention that one of the biggest problems with the global warming issue is that CO2 is invisible. I'll bet that if people actually saw giant clouds the color of liquid Barney wafting off the coast every day, then they would be more inclined to think of carbon dioxide as something tangible.
