First, there is no such thing as eagerness to tap the Arctic, so I have no idea why this article exists; it's a big troll. The TAPS pipeline has had declining volumes for decades. There's been talk (for years) of a gas pipeline but it's pretty much not going to happen, for a number of reasons that no one really gives a shit about.
Second, I'm from Valdez, Alaska. I was there for the spill, and for about twenty years afterwards. The long-term environmental impact is practically nil. Fish stocks recovered quickly, same with sea otter and sea lion populations, shorebirds, etc. The spill happened about twenty miles from my hometown. Yes, in a few beaches you can dig down and find a thin sheen of oil in the shale, but it doesn't seem to affect the critters much. Massive oil spills are not necessarily all that big of a deal.
Thirdly, the oil companies have small spills fairly often, and while the existing methods of cleanup may not scale, it's less of an issue all the time, and not necessarily the end of the world if it does happen. Also, there's not actually all that much opportunity for a large spill: we don't have gushers up there, or supertankers, and the pipelines can be shut down pretty quickly. They're monitored to some degree, usually with 'smart pigs' which travel inside the pipeline cleaning wax deposits and checking for damage. There was an incident a few years back where some drunken yahoo shot a hole in the pipeline, but it did not result in a large spill.
My sister works on the North Slope, in the oilfields. It's actually a really sensitive area environmentally, and the oil companies have to report even tiny spills. Also, it's really hard to build on permafrost without it melting and subsiding into a huge bog. You can't even drive cars on it without tearing it up, they use smaller golfcart type things most of the time. The wells and pads are as small as they can be. I'm not going to eulogize the oil companies for having a good environmental record up there, but they have been limited by the terrain, perhaps more effectively than regulations might have done.
This panel has its head up its collective ass, though, and this story is just trolling. It's not inevitable that there will be a big spill, and it's not necessarily a problem if it happens, and it's not something that we don't know how to deal with. There are a lot of current methods for cleanup that probably wouldn't work so well there, and I'm sure it's worth someone's time to figure out what the best way to clean up big oil spills in Arctic conditions, but "inevitable big Arctic oil spill" is just sensationalism. In other words, it's horseshit, and you've all been had.
