Summary

We have every reason in the world to try to stop climate change. But when it comes to geoengineering––lacing the atmosphere with particles to block the sun’s warming effect––experts are split on whether the intervention would create more problems than it would solve. At this rate of global warming, though, it’s hard to imagine a scenario in which humans won’t eventually try it out. Inadvertently, we’ve already piloted the method through air pollution. Is the geoengineering genie already out of the bottle? Should we even want to stop it? Are there ways to deploy these efforts that will insure against scenarios where we wish we’d never tried? Host Brian Beutler is joined by Elizabeth Kolbert, a New Yorker staff writer and author of Under a White Sky, and Dr. David Keith, a professor of geophysical sciences at the University of Chicago and an advocate for geoengineering research.

Hello and welcome to Positively Dreadful with me, your host, Brian Boyler.

0:43.6

There's a kind of darkly funny subplot in American history.

0:47.5

You may have seen it immortalized in the movie Oppenheimer, which is that the scientists who built

the first atomic bomb couldn't be completely certain that the chain reaction that produces

the explosion in a fission device wouldn't just continue forever and ignite the atmosphere

ending life on Earth. They were to be clear, pretty sure that wouldn't happen obviously,

or they wouldn't have detonated it, but they were playing for the very first time with powers

that were hard even for them to fathom and that frightened them. So, Boyler, the atmosphere

did not catch fire, but unleashing the nuclear gene carried other unintended consequences for humankind,

starting with the destruction of Hiroshima and Nagasaki, obviously, but also the radioactive fallout

of nuclear weapons tests and the thermonuclear arms race, mutually assured destruction.

1:41.7

On the other side of the coin, there's the clean energy of nuclear power, the theoretical

allure of fusion power, and those things that are offset by the very real harms of a few nuclear

meltdowns. Some day we might be able to pencil out whether it was all worth it, but wherever we

1:59.2

land on that question, it's hard to imagine a version of history where scientists became theoretically

aware that they could harness the power of the Sun, but then agreed for all eternity not to try.

Even absent the exigent circumstances of World War II, humans being humans, the nuclear age
