The larger reason we’re ignoring climate change is that Al Gore was right: This truth is just too inconvenient. Responding to climate change with the vigor that the threat deserves would not, contrary to legend, be devastating for the economy as a whole. But it would shuffle the economic deck, hurting some powerful vested interests even as it created new economic opportunities. And the industries of the past have armies of lobbyists in place right now; the industries of the future don’t.

The whole history of America since World War II caused an inertial transfer of power toward the executive branch. The monopoly on use of nuclear weaponry, the cult of the commander in chief, the worldwide network of military bases to maintain nuclear alert and supremacy, the secret intelligence agencies, the entire national security state, the classification and clearance systems, the expansion of state secrets, the withholding of evidence and information, the permanent emergency that has melded World War II with the cold war and the cold war with the "war on terror"—all these make a vast and intricate structure that may not yield to effort at dismantling it.
