re: OTOH, you cant watch one movie and suddenly be an all knowing expert
I don't know enough about such things to even guess.
We could go into a deep freeze in the next decade for all I know.
Changes ARE evident, especially the crazy weather we're getting.
Species are dying off, lakes and rivers are polluted, our food chain and agriculture is in danger, and Tom is saying my brain is full of crap.
Go figure.
Won't discuss the issue but is having fun at my expense again.
Still, I recommend that everyone make a choice to watch "An Inconvenient Truth".
