Inhofe’s last stand

Part of me felt a little nostalgic yesterday watching the last Senate hearing on climate change that will be chaired by Sen. James Inhofe. It all felt very familiar and comforting in some strange way. There was the well-spoken ‘expert’ flown in from Australia (no-one available a little closer to home?), the media ‘expert’ from the think tank (plenty of those about) and a rather out-of-place geologist. There were the same talking points (CO2 leads the warming during the ice ages! the Medieval Warm Period was warm! it’s all a hoax!*) that are always brought up. These easy certainties and predictable responses are so well worn that they feel like a pair of old slippers.

Of course, my bout of nostalgia has nothing to do with whether this was a useful thing for the Senate to be doing (it wasn’t), and whether it just provided distracting political theatre (yup) in lieu of serious discussion about effective policy response, but even we should sometimes admit that it is easier to debunk this kind of schoolyard rhetoric than it is to deal with the complexities that actually matter. The supposed subject of discussion was ‘Climate Change in the Media’ though no-one thought to question why the Senate was so concerned with the media representations (Andy Revkin makes some good points about it though here). Senators have much more effective means of getting relevant information (knowledgable staffers, National Academy of Science reports, the presidential office of Science and Technology etc.) and so this concern was concievably related to their concern with public understanding of science….. or not.

Naomi Oreskes did a good job on the context and provided useful rebuttal to a frankly ridiculous claim that contrarians were not getting any air time on the networks. One point she could have raised was that when Patrick Michaels made the same complaint to CNN – that their climate news stories weren’t ‘balanced’ – a quick scan of their interviewee lists revealed that the scientist most frequently on CNN …. was none other than Michaels himself. A result somewhat at odds with his standing in the community or expertise, but ample evidence for the ‘false balance‘ often decried here.

As for the scientific content, with the sole exception of Dan Schrag’s statements, it was a textbook example of abuse of science. Two exchanges summed it up for me. In the first, Bob Carter insisted that CO2 always follows temperature for the ice age cycles (which are paced by the variations in the Earth’s orbit and for which CO2 is a necessary feedback) and seasonal cycle (related mainly to Northern hemisphere deciduous trees) . Both statements are true as far as they go – but they don’t go very far. Was Carter suggesting that the 30% increase in CO2 decreased after 1940? or that it has stopped increasing in recent years (since he appears to also believe that global warming stopped in 1998?). As an aside by his criteria it also stopped in 1973, 1983 and 1990…. only it didn’t. Of course, if this wasn’t what he meant to imply (because it’s demonstrably false), why did he bring the whole subject up at all? Surely not simply to muddy the waters….
