Thanks. Bob Carter’s excellent lecture is in Part II.
By all means, buy the DVD and support Durkin. Just make sure you get the NTSC version, not the PAL version.
Here's an idea... Buy several. Donate one to the local library. See if your local video store will place one in the community service area (i.e., free rentals). Let's share this.
I still recommend watching the version floating around the Internet. The main reason is the DVD removes the comments from Carl Wunsch from MIT.
Wunsch's primary contribution to the documentary was to note that the oceans hold huge amounts of CO2, which gets released as the oceans warm. However, warming the oceans is not something that occurs fast due to their mass. It takes centuries. This is wholly consistent with the ice core samples that show CO2 rises are tightly correlated with temperature rises, but lag temperature by 800 years.
Gore's movie showed this extremely well, though Gore implied the reverse of the relationship. He doesn't actually mistate it directly, but Gore's words are so carefully parsed that the only impression one could have was that CO2 led temperature. The parsing was too careful and strikes me as deliberate dissemination.
According to Wunsch, Durkin misrepresented his view. Wunsch has said he absolutely believes in AGW. He said he meant to explain how the ocean's reservoir of CO2 could lead to runaway global warming if we allow the temperature to rise too far.
Durkin says Wunsch knew exactly how his segments would be used and has lots of correspondence with Wunsch to back it up. He also said Wunsch called him soon after the documentary aired, begging to be removed. Durkin said Wunsch received a number of phone calls from colleagues and needed to get pulled.
The claim that Durkin selectively edited Wunsch smells of coaching. In an earlier documentary about the extremes, excesses, and lunacy of the environmental movement, Durkin was accused of interviewing people who thought he was making a positive documentary about the greenies. It seems Durkin let them talk and let their most ridiculous statements condemn them. The greens orchestrated a campaign to refute and complain about the film and the politically correct oversight board required the station to make a public apology. Wunsch's claim appears to be made with an eye towards this past incident.
Wunsch's claim seems a lot like the past incident. Either someone fed this to Wunsch or Durkin and Channel 4 were extremely sloppy. Somehow, I doubt it's the latter since Durkin and Channel 4 would both be extremely careful not to allow a rerun. As a result, Durkin didn't interview naive greenies. He featured skeptics who knew what they were saying and how their segments would be used. Wunsch wants you to believe that he is the exception. Yeah. Okay.
Look, an MIT prof is no dummy. The runaway warming argument falls apart when you consider that the temperature forcings of CO2 are logarithmic in nature, so that CO2 has a diminishing marginal impact. At some point, adding more CO2 has virtually no effect.
This isn't controversial. It's even in the IPCC reports.
The only people who seem to ignore it are Al Gore and the political/Hollywood elites, which shouldn't be surprising. Leonardo DiCaprio has become wealthy by reciting the lines others write for him and pretending to be someone he's not. He may be extremely bright, but he definitely seems ignorant. It's entirely plausible this high school drop out doesn't even know what a logarithm is, let alone the underlying math. Wunsch, on the other hand, does understand this.
Watch the documentary with Wunsch and pay attention to see if it looks like Wunsch was selectively edited. If not, Durkin's explanation seems more plausible, which means this is a great example of scientific censorship by the AGW crowd.
