If the first rule of holesis to stop digging, the first rule of climate change is to stop putting carbon dioxide in the air. President Barack Obama seemed to take that approach in his historic June 25 climate speech when he addressed the proposed Keystone XL pipeline, meant to carry tar sands crude from the vast strip mines of Alberta, Canada, to refineries on the U.S. Gulf Coast. "Our national interest will be served only if this project does not significantly exacerbate the problem of carbon pollution," he said.
