If you've been thinking about global warming lately -- it's certainly hard not to be -- you'll want to watch this interesting BBC documentary, The Great Global Warming Swindle, no matter where you sit on this issue.

A number of scientists assembled by filmmakers argue the origins of global warming -- climate change -- may not be a man-made phenomenon after all. In fact, the Earth's existence is marked by a long history of climate changes, from a mini ice age during the 17th century to the Holocene Maximum, the warmest time recorded on our plant over the past 10,000 years.

Rather than let the loudest voices do the deciding for you, like con-ventional medicine that is corrupted by countless conflicts of interest -- most of which we know nothing about -- it's important for you not to accept the party line and do your own homework about global warming.
