Climate change, 350, and the human imagination.

I vividly remember my daughter Paloma at the age of six asking me if an atomic bomb hit the house next door would it also destroy our house.
It was an excruciating moment for both of us. Clearly, she’d just heard of atomic bombs and was anxious.
‘Darling,’ I said, ‘It would destroy the whole city.’
What else could I say?
A look of dread and wonder came over her face. She was struggling to grasp the concept. I felt sick at heart. How do you tell your kids?

I have a similar but less gut-wrenching memory of my son Rowan, about the same age discovering a bright light over the horizon long after the sun had gone down. He suggested that the sun’s glow could still be seen. A very natural thing for him to think. ‘No,’ I said, ‘that’s the city. The glow of Auckland’s lights.’
He didn’t believe me. He couldn’t conceive that the human made city could create such an effect, enough to rival natural events.

There’s a sense in which we are all children when it comes to trying to imagine that massive effects on the climate could be caused by an otherwise harmless gas that is an intrinsic part of the carbon cycle. Much of what we call climate change scepticism or denialism boils down to a sense of personal incredulity. It is a failure of the imagination. The problem is turning the dry glyphs of the scientists into a form that can open the imagination.

Science writer Bill McKibben, when founding the climate action group 350.org had to confront the problem directly. How to dramatise the C02 content in the atmosphere. He has attempted to turn a number into a metaphor, a universal signifier. Taking his cue from Senior NASA climate scientist, James Hansen, who has said that, to sustain human life, the maximum carbon dioxide level in the atmosphere should be no more than 350 parts per million[1], McKibben is attempting to universalise 350 as a symbol for the urgent need to stop putting greenhouse gasses into the biosphere. Part slogan, part logo, part scientific code, 350 aims to go beyond language. McKibben relates how he arrived at the idea:

I almost never write about writing—in my aesthetic, the writing should disappear, the thought linger. But the longer I’ve spent working on global warming—the greatest challenge humans have ever faced—the more I’ve come to see it as essentially a literary problem. A technological and scientific challenge, yes; an economic quandary, yes; a political dilemma, surely. But centrally? A crisis in metaphor, in analogy, in understanding. We haven’t come up with words big enough to communicate the magnitude of what we’re doing.[2]

After expressing his frustration with the host of metaphoric phrases he’d used in his writing, he continues,

It wasn’t enough, though, nor were any of the other such phrases (like “boiling point” or “climate chaos”) that more skillful authors have used since. So in recent years I’ve found myself grasping, trying to strip the language down further, make it communicate more. Then I started thinking about numbers.”

Describing Hansen’s 350 as a “revelation” and “a bright line,” he makes clear the political agenda,

…a number works. And this is a good one. Arcane, yes—parts per million CO2 in the atmosphere. But at least it means the same thing in every tongue, and it even bridges the gap between English and metric. And so we secured the all-important URL: 350.org. (Easier said than done.) And we settled on our mission: To tattoo that number into every human brain.’

Chilling to think that we are now over 400 parts per million.

How successful he has been in installing the meaning of 350 ppm into our imaginations may be matter debate, but 350.org has created some of the most thoughtful and innovative ‘protest installations’ yet seen, including a website apt enabling the visitor to 350.org to create their own climate change artwork.

Here are a few examples of 350’s imaginative approach to climate activism. Here’s one for sea-level rise:

Below, note the coincidence of 350 with the number of months passed since we have experienced a month in which temperatures have dropped below the 20th Century average.
