Some Republicans and conservatives are prone to an ideologically motivated skepticism. On AM talk radio, where scientific standards are not particularly high, the attitude seems to be: "If Al Gore is upset about carbon, we must need more of it." Gore's partisan, conspiratorial anger is annoying, yet not particularly relevant to the science of this issue.
This points, however, to a broader problem. Any legislation ambitious enough to cut carbon emissions significantly and encourage new energy technologies will require a broad political and social consensus. Nothing this complex and expensive gets done on a party-line vote. Yet many environmental leaders seem unpracticed at coalition building. They tend to be conventionally, if not radically, liberal. They sometimes express a deep distrust for capitalism and hostility to the extractive industries. Their political strategy consists mainly of the election of Democrats. Most Republican environmental efforts are quickly pronounced "too little, too late."
Even worse, a disturbing minority of the environmental movement seems to view an excess of human beings, not an excess of carbon emissions, as the world's main problem. In two recent settings, I have heard China's one-child policy praised as an answer to the environmental crisis -- a kind of totalitarianism involving coerced birth control or abortion. I have no objection to responsible family planning. But no movement will succeed with this argument: Because we in the West have emitted so much carbon, there needs to be fewer who don't look like us.
Human beings are not the enemy of sound environmental policy; they are the primary reason sound environmental policy is necessary.
If the movement to confront climate change is perceived as partisan, anti-capitalist and hostile to human life, it is likely to fail, causing suffering for many, including the ice bears. And so the question arises: Will the environment survive the environmentalists?
