During the same week when House Republicans passed a bill forbidding scientists from advising the EPA on its own research, NASA climate scientists (coincidentally but maybe inconveniently) released a video documenting A Year in the Life of Earth's CO2. According to NASA, "The visualization is a product of a simulation called 'Nature Run,'" which "ingests real data on atmospheric conditions and the emission of greenhouse gases and both natural and man-made particulates. The model is then left to run on its own and simulate the natural behavior of the Earth’s atmosphere." The video above visualizes how carbon dioxide in the atmosphere traveled around the globe from January 2006 through December 2006. Hopefully the take-away isn't look at all the pretty colors. The video is in the public domain and can be downloaded here.
