Dear friends,

Big news has just emerged: Dr. James Hansen, the planet’s premier climate scientist, announced his retirement as head of NASA’s Goddard Institute of Space Studies, where he began his career in 1967.

If 350.org has a patron saint, it’s Jim. It was his 2008 paper that gave us our name, identifying 350 parts per million CO2 as the safe upper limit for carbon in the atmosphere.

But as much as for his science, we respect him for his courage. He’s always been willing to speak the truth bluntly, from the day in 1988 when he told Congress that the time had come “to stop waffling so much and say the planet was warming,” to all he’s done to bring attention to damaging projects like Keystone XL — even to the point of risking arrest to do so.

I have no doubt he’ll go on doing science, and speaking plainly — indeed, he told the New York Times that one reason he’s leaving the federal payroll is so he can take on the government more directly.

But this is a big moment, and we need to mark it. Here’s what I hope you’ll do: honor Jim’s lifetime of work by making a public comment to the State Department about Keystone XL and tell them to reject the pipeline.

In this case, speaking out is simple — click the link below to go to the page to submit from. There’s a list of ten arguments to choose from – you can mix and match or put it in your own words and just speak from the heart.

Sending a message to the State Department might not seem like much, but I think it’s actually quite fitting tribute.

One reason we’re fighting the pipeline is because Jim Hansen did the math to show that if we combusted the tar sands on top of all else we burn, it would be “game over for the climate.” So far that message hasn’t gotten through: the State Department hired a bunch of compromised oil industry analysts to ‘review’ KXL, and unsurprisingly they decided it would have ‘minimal’ environmental impact. We need to get them to take reality seriously, and change that assessment.

Maybe — just maybe — with a truly overwhelming flood of comments, we can break through. Together with our friends across the movement, we’re aiming for an ambitious target of 1 million comments to the State Department to stop the pipeline.

Beginning this comment push is all the more timely after the disasterous tar sands pipeline spill in Arkansas, where thousands of gallons of toxic oil ran freely through the streets of a suburban community.

Jim Hansen has been to jail twice to try and block KXL. When I saw him in handcuffs, I cringed. I don’t mind going myself, but it seems crazy that we have to send our best climate scientist off in handcuffs; in a sane world he’d never have to leave the lab. And in a sane world we’d just be toasting his retirement from NASA with well-deserved champagne.

But it’s a crazy world, heating fast, and so we need to mark this historic day in a way that really counts.

Thanks,

Bill McKibben
