Carbon dioxide lifetime 50-100x longer than generally reported

There is a great deal of confusion regarding how long carbon dioxide (CO2) persists in the atmosphere. There are at least two reasons for this. The first reason is that there are multiple physical and biological processes that combine to remove CO2 from the air and they behave differently and at different speeds. Full Story »

This blog post provides a condensed digest of current articles on carbon dioxide. The story itself quotes no direct sources, but rather synthesizes stories from multiple sources to make its point. I wish the author had done a better job of proof-reading his work. It does provide information I hadn't seen before about the Orbiting Carbon Observatory, which was interesting. I don't believe this qualifies as a news report, actually, so I'm changing the story type to "News Analysis."

The article provides another report that carbon dioxide remains in the atmosphere much longer than hypothesized in earlier models. The full implications are not expounded upon, and the recommended action space is sparse.

Not highly technical, which makes it accessible for the common reader. Good structure with final fact recap and emphasis on main conclusions: CO2 life is longer than previously estimated and the absorption power available is pretty limited, with mechanisms not yet fully understood -- so, one more serious dilemma for mankind.

It only makes sense that the knowledge about CO2 cycles is far from being mastered. Before solving the problem of a cleaner air, we yet have to solve a scientific puzzle.

    () Several long-term climate models, though their details differ, all agree that anthropogenic CO2 takes an enormously long time to dissipate. If all recoverable fossil fuels ...
