Massive oil pipeline is threatened by thawing permafrost
The Trans-Alaska Pipeline, one of the world’s largest oil pipelines, could be in danger.
Thawing permafrost threatens to undermine the supports holding up an elevated section of the pipeline, jeopardizing its structural integrity and raising the potential of an oil spill in a delicate and remote landscape.
The slope of permafrost where an 810-foot section of the pipeline is secured has started to shift as it thaws, causing several of the braces holding up the pipeline to twist and bend.
