What Would It Take? Solving Climate Change



What would it take to shape a planet on which people, other living things, and the systems that support us can sustainably coexist? For a special issue, Momentum magazine invited experts from around the world to share their thoughts on how we might craft solutions to some of earth’s toughest challenges. Ben Jervey spoke with physicist Robert Socolow on what it would take to rein in greenhouse gas emissions and solve climate change. 

What would it take to rein in greenhouse gas emissions and solve climate change? 

The concentration of carbon dioxide in the atmosphere is about 40 percent higher today than it was 200 years ago. It’s going up principally because we are burning fossil fuels (coal, oil, and natural gas) and secondarily because we are cutting down forests. Fossil fuel energy represents 85 percent of the energy powering the world economy, and exchanging the current fossil fuel energy system for a low-carbon energy system won’t happen overnight. It could require a century or more if we fail to take climate change seriously. The current fossil energy system is a very strong competitor to any low-carbon energy system we will invent.

With all the talk about peak oil, it’s not surprising that people imagine that the fossil fuel era will come to an end soon, because we run out of fossil fuels. That’s not going to happen. What we will run out of is low-cost oil. But there are a lot of buried hydrocarbons in the form of lower quality reserves (coal, shale gas, shale oil, oil sands and others) that will keep the fossil energy system humming. So we are in a pickle. We will need policies that modify the current competition between high-carbon and low-carbon energy in favor of the latter. We will also need success in research, development, and deployment that lowers the cost of low-carbon energy.

You’ve expressed concerns about the current discussions of long-term climate targets.

If you truly wish to solve the "climate change" issue, stop talking about it. You're adding to the CO2 every time you open your mouth. There is no such thing as man caused climate change. The Earth will take care of itself as it has long before us and will long after us. Let it go. You cannot change what you cannot cause. Let it go.
