James Hansen's Failed Ultimatums: A Free Market, Anyone?

Predictions and ultimatums by learned, qualified scientists should be taken seriously. In the case of the father of the global warming scare, James Hansen, formerly a climate scientist with NASA/GISS, and now a full-time scientist/activist, the time is up on a remarkable ultimatum made ten years ago in the New York Review of Books. "We have at most ten years--not ten years to decide upon action, but ten years to alter fundamentally the trajectory of global greenhouse emissions," he wrote in his July 2006 review of Al Gore's new book and movie, An Inconvenient Truth. "We have reached a critical tipping point," he assured readers, adding "it will soon be impossible to avoid climate change with far-ranging undesirable consequences."
