I just got an action alert email from Robert Greenwald (director of several recent activist documentaries) on Fox News and their lies/distortions about global warming. Since I don't own a TV and therefore don't watch TV I don't see this in person, but I have watched Fox News a few times and they do seem to be totally slanted towards a certain Republican/Conservative oriented point of view that is often untruthful.
In any case ...
Here's a video they've prepared that's full of clips of Fox News trying to diss the presentation of ideas about global warming, and pushing a point of view which pigeon-holes global warming with other poppycock ideas. I suppose they're ignoring the vast majority of scientists who agree global warming is happening and is man-made.
There is a petition to sign here: http://action.sierraclub.org/foxattacks
Their idea is to send a petition to Home Depot demanding that Home Depot stop advertising on Fox.
