Haven't talked much about global warming lately. Fortunately, other folks have been busy. Here is one of the best videos I have seen in a long time.

My old site, Planet Restart, contains a lot of links to foundation documents, but go anywhere you like. Just do your own looking and your own deciding.
This is the single most important issue facing your children as they inherit the earth from us. Like the global economic meltdown, this is a mess we made that our kids will have to clean up. The least we can do is look the problem straight in the eye, accept responsibility and start taking effective measures to deal with it.
