The Lone Ranger used them. They’re supposed to kill werewolves. They seem like a cool idea, one that could possess magical powers. But when it comes to environmental messaging, they are not much good.
In a previous post I covered the balance of fear and hope required to move people to action on climate change. Too much fear, and action disappears, replaced by fatigue and apathy. The opposite may also be true. Too much hope or positive news and your audience won’t take action because it seems our problems are about to be solved.
Nowhere is this issue of overly optimistic predictions more prevalent than in the area of “science-media reported” silver bullets. In most cases these regard the next tech miracle that will save us from climate catastrophe.
To understand this let’s take a look at an example, “the synthetic leaf.” Imagine a device much like a photovoltaic cell that takes sunlight and CO2 from the air and converts it into energy and fuel using photosynthesis. After all, this is what trees and plants do. We could build billions of these, and they would suck CO2 from our atmosphere and power the globe. You’re getting excited now aren’t you?
The trouble is that we’ve been working on artificial photosynthesis for decades. Technological breakthroughs take time, require commercial finance, and public policy and support. Many breakthroughs wind up on the trash pile of hope. Like our news journalists, science writers are also click-obsessed. So we use terms like “breakthrough,” “revolutionary,” and “game changer” to describe the slow process of science and technology. While this kind of reporting gets clicks for articles, it does little to help move the public to action.
There is a whole set of media messages that are shared with the public around creating energy or the potential for geo-engineering our way out of climate change. Some of these are even propagated by climate deniers and skeptics as a means for saying don’t worry if climate change is true. Here are just a few of these silver bullets you might have heard.
- Nuclear fusion
- CO2 capture
- SO2 cloud seeding
- Space-based sun shields
- Algae fuel
- Clean Coal
Research is essential to making progress against climate change. We need to invest in research and technology, and not cut budgets as proposed by the current administration. But we also need to be careful in communicating silver bullets that can lull us into complacency. We need green bullets on how to help.
Here’s a useful metaphor and story. It’s pretty simple. When I was a kid, I told my father I wish he’d stop smoking. He replied that they’d have a cure for cancer by the time he got it. He died of smoking related cancer twenty years later. We still have no cure, except to stop smoking. It’s the same with our use of fossil fuels for energy. No silver bullets.
We are all connected. Savor the earth.
