Ten of the nationโs top climate scientists penned a letter to Secretary of State Hillary Clinton today questioning why the State Department isn’t considering the enormous climate change impacts of developing the Alberta tar sands in its review of the controversial Keystone XLย export pipeline project.ย
โAt the moment, your department is planning to consider the effects of the pipeline on โrecreation,โ โvisual resources,โ and โnoise,โ among other factors,โ the scientists wrote. โThose are importantโbut omitting climate change from the considerations is neither wise nor credible.โย
ย
The State Department is currently accepting comments on the scoping evaluation that will determine what environmental considerations will be included in the supplemental environmental impact statement (SEIS) required for the northern leg of the Keystone XL pipeline.The public comment period ends July 30.
ย
The departmentโs previous draft EIS downplayed the climate risks of Keystone XL, arguing that the Alberta tar sands would be developed with or without it, so therefore the Obama administration has no accountability for the additional global warming pollution that will result from burning dirty tar sands oil.ย
ย
In a press release announcing the letter, May Boeve, Executive Director of 350.org, said:
ย
โKeystone became the biggest environmental cause of Obama’s first termโand the reason most of those who marched and went to jail gave for their concern was the climate impact of those vast tar sands. It would be ironic in the extreme if the State Dept. didn’t take the issue seriously in its review.โ

July 17, 2012ย
ย
Dear Secretary Clinton,
ย
We are writing to ask that the State Department conduct, as part of its evaluation of the Keystone XL pipeline proposal, a serious review of the effect of helping open Canadaโs tar sands on the planetโs climate.
ย
At the moment, your department is planning to consider the effects of the pipeline on โrecreation,โ โvisual resources,โ and โnoise,โ among other factors. Those are importantโbut omitting climate change from the considerations is neither wise nor credible. The vast volumes of carbon in the tar sands ensure that they will play an important role in whether or not climate change gets out of hand; understanding the role this largescale new pipeline will play in that process is clearly crucial.
ย
We were pleased that President Obama saw fit to review this project more carefully; it would be a shame if that review did not manage to comprehensively cover the most important questions at issue.
ย
Sincerely,
ย
