The Pipeline that just won’t die is rearing its ugly head again today as the Senate is considering legislation to resurrect Keystone XL by overriding President Obama’s rejection of the project, and greenlighting construction of this catastrophic idea.

In response, activists and groups like 350.org, MoveOn, the Sierra Club and Climate Progress are putting together what they expect will be a massive response to show the Senate that approving Keystone is unacceptable — politically, morally and environmentally. (For details and background, the Natural Resources Defense Council (NRDC) compiled an extensive document making clear how problematic the project really is.) The goal is to blitz the Senate with at least 500,000 messages in the next twenty-four hours imploring the reps to stop the pipeline, which would be the most concentrated burst of environmental advocacy this millennium.

As author and environmental leader Bill McKibben wrote yesterday, "This Congress is clearly not going to solve global warming — no one expects Harry Reid to work miracles, converting implacable Republican opponents. But they can clearly hold the line if they want to. Maybe a letter or two — or half a million all at once — will nerve them up." Join the call today!
