Oh and they do have a dvd available through their own website if it was interesting enough for you to use in real life with your lectures but for the time being I will hunt down a new link for you.
Run time is a little over an hour, it basically proves what you said a few posts up, in every aspect, all the studies that prove we are the cause are misinterpreted or falsified and these guys actually did a lot of research which shows instead that during our most productive times (after the war) it was COLDER than it is now and that its been a lot hotter than it is now thousands of years ago, they sum up the cycle of the Earth that you stated about.
Also the impact of the sun that no-one seems to take into consideration, they said that even if our emissions contribute to some kind of warming effect its literally in the single digit percentage compared to what the sun can and does do to the Earth.
Anyway, well worth a watch if you get a lazy afternoon with an hour to kill so I will pop a link back later
