If the new forecast of a decade of cooler temperatures in North America and Europe pans out, it will pose a substantial challenge to climate campaigners, politicians, and citizens: Can they produce meaningful action to limit the long-term warming that scientists still say is clearly ahead under a building greenhouse blanket even when it’s cooling outside?
[Insert, July 14, 2009 | There’s new support for the idea that warming will be on hold for awhile. But variability is such that Joe Romm may still be right with this prediction. Time will tell.]
One thing that may make this an even tougher challenge is the tendency of some campaigners recently to portray global warming as an unfolding catastrophe here and now. I’ve been criticized by some environmentalists in recent years for writing that the long-term picture (more CO2 = warmer world = less ice = higher seas and lots of climatic and ecological changes) is the only aspect of human-caused global warming that is solidly established, and that efforts to link dramatic weather-related events to the human influence on climate could backfire should nature wiggle the other way for awhile.
Some activists agreed, including Dave Roberts at Grist. His 2006 post also cited a warning to environmentalists from James Hansen, the NASA climatologist. As Dr. Hansen put it at the time:
I am a little concerned about this, in the sense that we are still at a point where the natural fluctuations of climate are still large — at least, the natural fluctuations of weather compared to long-term climate change…. So we don’t want the public to hang their hat on a recent storm, recent hurricanes for example, because those will fluctuate from year to year.
[Insert | Michael Schlesinger of the Univ. of Illinois noted the cautionary conclusion of a climate paper he co-authored with Natalia Andronova in 2000 that says something very similar.]
It’s much harder to build a movement around limiting losses for generations unborn than for ourselves, but if honesty counts, that may be the only way to make climate action stick. Of course, another approach is to build the argument for new non-polluting energy norms around the many benefits — along with climate insurance — that could come from finding abundant, renewable sources.
But that approach, too, can be held hostage to vagaries in energy prices. If there is a worldwide recession, say, and oil drops back to $60 a barrel for awhile, will the United States get lulled into another somnolent period like the 1980s through the 1990s, when energy vanished as an issue — through Republican and Democratic congresses and presidents? (In a video accompanying an earlier post, you can see former President Clinton discuss his energy legacy.)
The reality is that we don’t have much of a track record of working for the long haul these days. The oil shocks of the 1970s were followed by low prices, and away went almost all the research and efficiency initiatives that might have reduced American dependence on imported oil (and CO2 emissions). Political debates over the eventual insolvency of Social Security and Medicare are perpetually punted to the next Congress and president. In fact, some experts I’ve talked to over the years actually say global warming has a lot more in common with those looming financial risks than with classic pollution problems like smog and sewage.
One central question I’m exploring with Dot Earth is this: Can a species that evolved as an opportunist (grab those berries, gorge on that fallen antelope) and responder (fight or flee) meaningfully integrate evidence of long-term risks provided by science (on climate) or economics (on Social Security) and act for the sake of the future?
It all reminds me of stages of an individual life. As I’ve said many times before in talks (video of a sustainability talk at Yale), it seems that we’ve been locked in teen-style cow-tipping mode for a couple of centuries, with fossil fuels substituting for testosterone. Now science is kind of like the adult in the room, admonishing the teenagers to clean up their mess and do their homework before it piles up to catastrophic proportions.
In short, the question is: Can we grow up?
