Study Dismisses Geoengineering Quick Fix For Global Warming

Politicians should not look to science and engineering for a relatively quick fix to effectively deal with climate change caused by rising greenhouse gas emissions, a new academic study has determined.

The only solution to global warming is a massive rejection of toxic fossil fuels, vastly improved energy efficiency and substantially altered human behavior, found the recently released study — An interdisciplinary assessment of climate engineering strategies.

In light of their limitations and risks, climate engineering approaches would best serve as a complement to — rather than replacement for — abatement, and the latter should remain a focus of climate-change policy for the foreseeable future,” said the study written by six academics in the U.S. and Canada.

How to Get a Liberal to Question Global Warming

Readers of my posts will know that I’ve often focused on the work of Yale’s Dan Kahan and his colleagues, who have published fascinating research on how our political and cultural views skew our perceptions of scientific reality. In particular, Kahan et al find that “hierarchical-individualists” (aka conservatives) have very different responses to a variety of facts than do “egalitarian-communitarians” (aka liberals), and that these responses spring not from objective assessments of the evidence, but rather, from deeply seated worldviews that color our perceptions of what is true.

Such research has often been interpreted in a way that has made conservatives look, well, kinda bad. In one Kahan study, for instance, hierarchical-individualists overwhelmingly rejected the very idea that a scientist could be considered a real and legitimate “expert” because of that scientist's opinion that global warming is real and caused by humans. This is not exactly what I would call open-minded behavior.

But the research coming out of the Kahan group is actually quite balanced and does not merely target conservatives. And since I myself am often drawing on these sort of studies to criticize the right, I think it’s only fair to discuss a new Kahan et al study that, if you look closely, appears to show liberals also reasoning in a biased fashion.

[Don’t worry: I still think conservatives have much more deeply rooted issues with science. But it’s a complicated world out there, and it isn’t like liberals and environmentalists are complete innocents all the time. In my view, if we're going to criticize our ideological opponents, we've also got to try hard to see our own blind spots.]

So how do you get liberals to behave in a manner that, at least to my mind, might be called ideologically biased?

Andy Revkin Reviews Bjorn Lomborg's New Film 'Cool It'

Andy Revkin has posted an initial review on his Dot Earth blog about Bjorn Lomborg’s new film ‘Cool It.’

Head over to Dot Earth to read the whole thing, but here is an excerpt of important points and observations from Revkin about the film:

In “Cool It,” Lomborg breezily ticks down a laundry list of high-tech ways to engineer the atmosphere, for example, but punts on the tougher questions related to such planet-scale enterprises — such as the inevitable diplomatic dispute over who sets the planetary thermostat and how blocking the sun does nothing to stem the buildup of carbon dioxide, much of which will stay in the atmosphere for many centuries.

He proposes spending tens of billions of dollars (a bargain, he insists, compared to the hundreds of billions that would be spent on a cap-and-trade style approach), but he doesn’t say how he’d convince the United States or China to adopt the necessary carbon tax.

And he doesn’t deal with the full pipeline for innovation that is required to take a promising technology from idea to breakthrough. A greatly intensified research effort is a vital, but insufficient, facet of any plan to foster progress without disrupting the climate.

Its chiding tone in places is unlikely to build the sense of consensus and excitement around an energy quest that Lomborg seems to desire.
