An excellent reference to have in case there were any questions. I browse through various websites and still find conversations about how governments are somehow manipulating the media to say that global warming is not real. This link is for the naysayers.

A good movie on global warming & environmental concerns in general is Home, which is free on YouTube & available in a half dozen different languages.  I recommend it to anyone concerned about this issue.

Thanks for the link, Narz, the movie looks terrific.
