Presidential decisions often turn out to be far less significant than imagined, but every now and then what a president decides actually determines how the world turns. Such is the case with the Keystone XL pipeline, which, if built, is slated to bring some of the “dirtiest,” carbon-rich oil on the planet from Alberta, Canada, to refineries on the US Gulf Coast. In the near future, President Obama is expected to give its construction a definitive thumbs up or thumbs down, and the decision he makes could prove far more important than anyone imagines. It could determine the fate of the Canadian tar-sands industry and, with it, the future well-being of the planet. If that sounds overly dramatic, let me explain.
Sometimes, what starts out as a minor skirmish can wind up determining the outcome of a war—and that seems to be the case when it comes to the mounting battle over the Keystone XL pipeline. If given the go-ahead by President Obama, it will daily carry more than 700,000 barrels of tar-sands oil to those Gulf Coast refineries, providing a desperately needed boost to the Canadian energy industry. If Obama says no, the Canadians (and their American backers) will encounter possibly insuperable difficulties in exporting their heavy crude oil, discouraging further investment and putting the industry’s future in doubt.
The battle over Keystone XL was initially joined in the summer of 2011, when environmental writer and climate activist Bill McKibben and 350.org, which he helped found, organized a series of non-violent anti-pipeline protests in front of the White House to highlight the links between tar sands production and the accelerating pace of climate change. At the same time, farmers and politicians in Nebraska, through which the pipeline is set to pass, expressed grave concern about its threat to that state’s crucial aquifers. After all, tar-sands crude is highly corrosive, and leaks are a notable risk.
