The Associated Press: UN sees new peril in Asia's huge brown cloud cover

The enormous cloud masses can move across continents within three to four days, illustrating the fact that the phenomenon is not just a regional urban issue but a global one, said lead scientist, Veerabhadran Ramanathan, with the Scripps Institution of Oceanography at the University of California in San Diego.

"The main message is that it's a global problem. This is not a problem where we point fingers at our neighbors. Everyone is in someone else's backyard," said Ramanathan.

Right. If we're talking about real pollution, we shouldn't point fingers at Asia. If we're talking about carbon dioxide (which is not a pollutant), that's when we should point fingers--at the U.S.
