Uncertainty is not the enemy
Dec. 1st, 2009 10:33 pm"Doubt is our product, since it is the best means of competing with the ‘body of fact’ that exists in the mind of the general public."

"Gate? What gate?"
- The Monster in the Darkness, in the webcomic Order of the Stick by Rich Burlew
There's no use at this point trying to ignore "Climate-Gate" or claim it's somehow meaningless. The timing, so close to the opening of the Copenhagen climate negotiations, is highly suspicious, but if the emails were faked, the University of East Anglia would surely have said so. It seems likely enough that the hacker who "liberated" them waited until a politically propitious moment to release them to the world, but that doesn't change the importance of what they say.
On the other hand, it's foolish to claim, as countless conservatives are now doing, that the emails prove anything in particular about the future of climate change. What they do is increase the uncertainty. Scientists at one of several important climate research centers, frustrated by complex and inconclusive data sets and angry about the continued threats to their efforts to convince themselves their research was of epic global importance, made some very bad decisions that make them look like Michael Crichton villains. This does not prove that all the data on which the IPCC based its most recent statements about the likelihood that humans are warming the Earth is automatically discredited. It certainly doesn't mean we can use the recent tree-ring data, which for whatever reason flatly contradicts measurements from actual thermometers (and glaciers), to argue that the world has actually been cooling during the 20th century.
After all, science itself is not actually in the business of proving anything. A scientific "fact" is only accepted as long as no evidence comes along to falsify it, and no part of the scientific edifice is immune from that possibility. The basic theory of evolution, for example, is considered to be "fact" because we've seen enough evidence, in both the fossil record and short-life-cycle species living today, that supports it. The theory of anthropogenic global warming has been moving in the direction of fact for decades, had nearly reached it with the most recent IPCC report and its 90% certainty level, and has now taken a step in the opposite direction; how large a step is presently hard to say.
But as politically unfortunate as this may seem for progressives, and as much as people with little understanding of the scientific method may try to distort the situation with simplistic sound bites, the trend toward sustainability is far from over. Clean renewable energy, in particular, still looks like a good move to people living in areas prone to asthma from smog or cancer from oil processing chemicals, as well as windy or sunny regions with depressed job markets. For the U.S. government, pollutants other than CO2 ought to provide ample reason to maintain the moratorium on new coal-fired power plants. And as for the international community, it has basically already given itself a one-year deadline extension, so the massive ramp-up in the climate movement's activities during 2009 may yet have time to take greater effect, as well as adjusting its rhetoric to the ever-shifting, always approximate scientific picture of reality.
It's hard to make major policy decisions, or take decisive action of any kind, in an uncertain world. But as long as the Age of Reason lasts, we will have to continually face that challenge and balance the probabilities as best we can.
