Good info on Global Warming - Why we should be Concerned

I stumbled across this in my local library the other day and it turned out to be a great source for climate information. It is a mini lecture series on "Earth's Changing Climate" taught by Dr. Richard Wolfson of Middlebury College. Dr. Wolfson takes the viewer through a number of arguments supporting global warming and explains why and what data supports this theory.

What I found most interesting about this mini-lecture series is how he covers carbon content of the air and arctic ice samples. He shows a very good correlation between atmospheric carbon dioxide and temperature over long periods of time. He also shows many graphs and gives the viewer a good foundational view of this topic. At some points I found it a little rudimentary but overall it covers the subject well. Go to your library and check it out...
