Still, the president can say no. If he does, then no pipeline -- and in the words of Alberta's oil minister, his province will be "landlocked in bitumen" (the basic substance from which tar-sands oil is extracted). Even energy-hungry China, eager as it is for new sources of fossil fuels, may not be able to save him, since native tribes are doing a remarkable job of blocking another proposed pipeline to the Canadian Pacific. Oil, oil everywhere, and nary a drop to sell. (Unfortunately that's not quite true, but at least there won't be a big new straw in this milkshake.)
An Obama thumbs-down on the pipeline could change the economics of the tar sands in striking ways. "Unless we get increased [market] access, like with Keystone XL, we're going to be stuck," said Ralph Glass, an economist and vice-president at AJM Petroleum Consultants in Calgary.
Faced with that prospect, Canada's oilmen are growing desperate. Earlier this month, in a classic sleight of hand, they announced plans for a giant "carbon capture and sequestration" scheme at the tar sands. That's because when it comes to global warming, tar sands oil is even worse than, say, Saudi oil because it's a tarry muck, not a liquid, and so you have to burn a lot of natural gas to make it flow in the first place.
Now, the oil industry is proposing to capture some of the extra carbon from that cooking process and store it underground. This is an untested method, and the accounting scheme Alberta has adopted for it may actually increase the province's emmissions. Even if it turns out to work perfectly and captures the carbon from that natural gas that would have escaped into the atmosphere, the oil they're proposing to ship south for use in our gas tanks would still be exactly as bad for the atmosphere as Saudi crude. In other words, in the long run it would still be "essentially game over" for the climate.
The Saudis, of course, built their oil empire long before we knew that there was anything wrong with burning oil. The Canadians -- with American help, if Obama obliges the oil lobby -- are building theirs in the teeth of the greatest threat the world has ever faced. We can't unbuild those Saudi Arabian fields, though happily their supplies are starting to slowly dwindle. What we can still do, though, is prevent North America from becoming the next Middle East.
So there will be a battle, and there will be nothing complicated or abstract about it. It will be based on one question: Does that carbon stay in the earth, or does it pour into the atmosphere? Given the trillions of dollars at stake it will be a hard fight, and there's no guarantee of victory. But at least there's no fog here, no maze of technicalities.
The last climate bill, the one the Senate punted on, was thousands of pages long. This time there's a single sheet of paper, which Obama signs" or not.
