First of all, there is crass politics being played on both sides. For the life of me I can't understand why right wingers in the U.S. are so concerned about a pipeline that will be built by a foreign company to ship foreign oil to the Gulf coast for the filthy refining job to be shipped to overseas markets. It's perhaps an interesting side issue, but our House of Representatives has reacted as if carrying water for Keystone and the oil companies in Canada is at the top of their list of things to do for the U.S. It makes no sense. As a Canadian, I guess I understand your concern, but see no reason why a U.S. political system should hop when Canadians say 'jump' or why anyone on this side of the border not directly affected, roughly 99.99% of the U.S., has more than a passing interest.Now, your US Supreme Court can be highly political but I've yet to see any comments that imply the Nebraska State Supreme Court is also ideological and political. The delays in process can all be laid at the feet of Obama and his administration for crash political reasons - he wanted/wants neither to upset the environmentalist and billionaire eco-nuts who largely funded his two elections nor his friends in the construction and oil patch unions. Obama has had numerous opportunities to approve the project - his State Department has approved it I believe three times after reviews and he's sat on his ass - so it's pretty rich now to blame a court in Nebraska for the project not being approved and to, by extension, try to blame that on Republicans.
First of all, as I said, I mostly agree with you that the pipeline will have little effect - you quoted me saying the oil is coming out of the ground one way or another. But the fact is the captured carbon in the oil sands IS significant in relation to the big picture. It's not the only problem, but there is no ONE step that if taken will all by itself address the problems of carbon and climate change, if carbon is a serious threat. So saying about each source of carbon, THAT one by itself if addressed will not solve the issue, is just a convenient way to throw up one's hands and say let's do nothing at all.As for climate scientists being on Obama and the environmentalist's side as it relates to Keystone, that's just utter nonsense. Even those who believe deeply in AGW unanimously agree that transporting oil over pipelines is better for the environment than transporting it over train, truck, or tanker. In addition, the effects on the environment related to the oilsands are miniscule in relation to the 40% of energy the US gets from coal fired electricity and the obscene 80-90% that India and China produce out of their coal fired electricity plants, fueled primarily by Obama's 50% increase in the production and export of US coal.
I haven't been dancing around or thumping my chest on this issue at all. You brought up the issue, and I addressed it rationally and calmly, even agreeing with much of your point about AGW and the oil sands.You can dance around and thump your chest all you want about this being about the environment, but we all know that's just nonsense.
