Glory Versus the Curse of the Black Carbon
Oct 15, 2010 09:14:58 AM | Adam Voiland
-
- Kick back, make yourself some popcorn, and enjoy one of the newe offerings from NASA Television: a tongue-in-cheek trailer about the horrors of aerosols. Black carbon plays the villain and the sooty particle (which comes from wildfires, campfires, various industrial processes, and diesel fumes) gets the blame for “cursing” atmospheric scientists with a “scourge of ignorance”.
