George Jahn's AP Article With a Graph of Maybe a Nuclear Explosion
I have been writing about the title article over at Nuclear Diner. Since it's a developing situation, it's in the forum, and others have chimed in. Many links and my own thoughts starting here and scroll down. Jahn has come up with a counter to the large degree of criticism that has been launched at him, and I work through that here (also findable by scrolling).
