James Lovelock's thesis can be refuted by finding examples where democratic forces are pushing FOR environmental safegaurds (and are hampered by UNdemocratic forces), or by showing examples where a lack of democracy leads to worse environmental policies. It's pretty trivial to find both kinds of examples.
Let's consider the first type. For years, the citizens of most democratic governments have been pushing for harder environmental legislation, but the governments have lagged behind the will of people, at a rate which depends on how much the government is beholden to other interests (in other words, how UNdemocratic the government is). In Europe, for example, the countries with the strongest and healthiest democratic forms have the best environmental record. Switzerland, which has a direct democracy (in which citizens vote directly to implement policy) has the best environmental footprint in contentinal Europe. The United States is an excellent example. Goverment policy here has long lagged behing public desires. Take the Kyoto protocols, which were overwhelmingly supported by the American population If you look at the polls, even most Bush supporters were in favor of the KP's, but were convinced that Bush supported them too. That's a triumph of corporate media control, and an indicator of dysfunctional democratic mechanisms.
What about undemocratic government? Well, that's a pretty easy one. It might be possible to find totalitarian regimes that take good care of the environment, but they are really in the minority. I can't think of any examples. Yes I know China is taking the lead in green technologies, but that's an economic strategy, and not an environmental strategy. Consider Russia, which is a nightmare, and was equally bad under Soviet control.
No, the solution to global warming is more and healthier democracy. If you just step outside of the United States, the global warming contraversy is over, finished. If you talk to a hundred people you might find one or two deniers, and if you talk to a hundred scientists, you might find one or two skeptics. But in a democracy that's an overwhelming majority. The problem, which is especially bad in the United States, is an undemocratic system which simply doesn't follow the will of the people (if you deny this, keep in mind that 70% of american supported a public option in the health care reform). The system breaks down largely because of a corporate media oligarchy with a complex web of ownership and agreements, which lends more weight to positions which favor corporate interests. But that's a lack of democracy, not a problem of too much democracy.
I gotta say, the headline of this article got my dander up. Elites institution, privileged individuals, and their well paid apologists have been campaigning against an "excess of democracy" as long as the notion of democracy has existed. Using the global environmental catastrophe as another front in this battle makes me livid. The fact is that the common citizenry of the plan have the most to lose from global climate change, and as such, we are the best deciders of our interests. The "enlightened men", the nobility, the "better classes of man", are the ones that have gotten us to this place, and I certainly don't trust them to get us out of it. The average citizens of the planet have a lot more in common interests with each other (especially regarding the climate) than do the elite institutions, governments, and corporations. They are far more likely to sacrifice our well being for the sake of their own interests.
I'll repeat: what we need is more democracy, not less.
