On January 23, Bloomberg News reported Warren Buffett's Burlington Northern Santa Fe Railway (BNSF), owned by his lucrative holding company Berkshire Hathaway, stands to benefit greatly from President Barack Obama’s recent cancellation of the Keystone XL pipeline.
If built, TransCanada's Keystone XL (KXL) pipeline would carry tar sands crude, or bitumen (“dilbit”) from Alberta, B.C. down to Port Arthur, Texas, where it would be sold on the global export market.
If not built, as revealed recently by DeSmogBlog, the grass is not necessarily greener on the other side, and could include increased levels of ecologically hazardous gas flaring in the Bakken Shale, or else many other pipeline routes moving the prized dilbit to crucial global markets.
Rail is among the most important infrastructure options for ensuring tar sands crude still moves to key global markets, and the industry is pursuing rail actively. But transporting tar sands crude via rail is in many ways a dirtier alternative to the KXL pipeline. “Railroads too present environmental issues. Moving crude on trains produces more global warming gases than a pipeline,” explained Bloomberg.
A key mover and shaker behind the push for more rail shipments is Warren Buffett, known by some as the “Oracle of Omaha” – of “Buffett Tax” fame – and the third richest man in the world, with a net worth of $39 billion. With or without Keystone XL, Warren Buffett stands to profit enormously from multiple aspects of the Alberta Tar Sands project. He also, importantly, maintains close ties with President Barack Obama.
WHEN it comes to climate change science, as with most things in life, it pays to listen to actual experts with a solid background in their field.

Roger Cohen is the former Manager of Strategic Planning and Programs at ExxonMobil Corporation.
He is a George C. Marshall Institute “Expert,” and has led a push for the American Physical Society (APS) to weaken their position on climate change.
Cohen became involved in studying global warming when Exxon realized that its “business environment” could be affected.
