Today's State Department endorsement of the controversial Keystone XL pipeline certainly boosts President Donald Trump's already-gaudy credentials as a world class climate change denier, but it's not clear that it will accomplish much of anything else. On paper, the TransCanada Corporation now has the Trump administration's blessings to add hundreds of miles of pipeline to allow hundreds of thousands of gallons of crude produced by the Alberta tar sands to flow daily into the U.S., a permission twice denied by President Barack Obama two years ago (by veto and by outright denial of its permit), but it's premature to assume the project will actually get built.
