  1. That camera set up seems masochistic : )  I can't imagine shooting a documentary in raw on the 5DII and trying to focus with that VAF filter in the way. Add Minolta adapted lenses on top of it- this is really quite a contraption and my hats off to them for pulling it off!

    I got into environmental documentary making because too many of the ones I watched had a shallow understanding of the issues, particularly their social and political contexts. This film seems to have fallen into similar traps by conflating scientific and political disagreement. When one is not an expert it is very important to figure out who is credible and not to rely on expert sources who are not experts on the subject matter at hand, or even still current in their fields.

    Sadly Dyson falls into that latter camp and his criticism of climate models is simplistic and ideologically driven. For a brief treatment of Freeman Dyson's views on climate change and other environmental problems written by working climate scientists, see this post over on RealClimate. RealClimate is also a place to go behind the news headlines and overly credulous assessments of single scientific papers by the press, and to ask questions. The scientists there personally answered my questions related to global warming and helped me understand a disagreement between scientists I had been talking to.

    More importantly, all of the things Dyson argues “heretically” should be looked at — e.g. land carbon sequestration or the lessons from the Altithermal period around 8000 years ago — are in fact already being intensively investigated and are not turning up any silver bullets to allay concern about climate change. When push comes to shove, Dyson is really only offering warmed-over standard contrarian talking points. Heresy, or more broadly an outsider’s viewpoint, can be a good thing when it shakes loose new ideas. But surely, we have a right to expect a more original form of heresy from the architect of Dyson spheres and nuclear starships.

    In short, it’s not so simple as the ‘self delusion’ Brower talks about. Dyson is not doing science, but he is deluding others under the guise of science. Given’s Dyson’s evident love of science (and expertise in it), that’s the part that we still don’t get.
