Global Warming Watch: How Carbon Dioxide Bleeds Across The Earth

High concentrations of carbon dioxide (in red) tend to congregate in the northern hemisphere during colder months, when plants can't absorb as much from the atmosphere.

Red alert — the amount of carbon dioxide in the atmosphere is increasing year-by-year due to human activity. It’s leading to a warming Earth, but just how quickly — and how badly it will change the environment around us — is hard to say.

NASA released a new video showing how carbon dioxide — a product mainly of fossil fuels — shifts during a typical year. Billed as the most accurate model to date, the emissions shown in 2006 (tracked by ground-based sources) show how wind currents across the globe spread the gas across the globe. The red you see up there indicates high concentrations. The full video is below the jump.
