Thanks for finding stuff like this DA. It's always good to be reminded how intricate and sensitive the web is.

I recall hearing about a connection between U.S. particulates and increased rain in N.Africa. Since we cleaned things up back in the 70's & 80's, N.Africa became much drier. I wonder if our increasing forest fires are helping N.Africa now?
