Eco-warriors are losing the public relations battle on global warming — and it’s driving them batty.

Take environmental writer Steve Zwick. Writing for Forbes.com, Zwick has called on so-called “climate deniers” to be treated like virtual war criminals: “We know who the active denialists are–not the people who buy the lies, mind you, but the people who create the lies,” he writes. “Let’s start keeping track of them now, and when the famines come, let’s make them pay. Let’s let their houses burn until the innocent are rescued. Let’s swap their safe land for submerged islands. Let’s force them to bear the cost of rising food prices. They broke the climate. Why should the rest of us have to pay for it?”
