Under a White Sky: The Nature of the Future

“Drive out nature though you will with a pitchfork,” Horace wrote in 20 B.C., “yet she will always hurry back, and before you know it, will break through your perverse disdain in triumph.”

The river’s choice would now be dictated for it, its flow maintained as if it were forever the Eisenhower era.

The first government report on global warming—though the phenomenon was not yet called “global warming”—was delivered to President Lyndon Johnson in 1965. “Man is unwittingly conducting a vast geophysical experiment,” it asserted.

In 1974, Mikhail Budyko, a prominent scientist at the Leningrad Geophysical Observatory, published a book titled Climatic Changes. Budyko laid out the dangers posed by rising CO2 levels but argued that their continued climb was inevitable: The only way to hold down emissions was to cut fossil-fuel use, and no nation was likely to do that.

“In the near future, climate modification will become necessary in order to maintain current climatic conditions,” Budyko wrote.

What the technology addresses are warming’s symptoms, not its cause. For this reason, geoengineering has been compared to treating a heroin habit with methadone, though perhaps a more apt comparison would be to treating a heroin habit with amphetamines. The end result is two addictions in place of one.

they’d need constant replenishing. If the SAILs flew for a few decades and then, for whatever reason—a war, a pandemic, unhappiness with the results—they stopped, the effect would be like opening a globe-sized oven door. All the warming that had been masked would suddenly manifest itself in a rapid and dramatic temperature run-up, a phenomenon that’s become known as “termination shock.”

“I don’t know if you ever feel pressure like this as a writer,” Schrag said. “But I see a lot of pressure from my colleagues to have a happy ending. People want hope. And I’m like, ‘You know what? I’m a scientist. My job is not to tell people the good news. My job is to describe the world as accurately as possible.’

He pointed out that if you believed the climate to be inherently unstable, the last thing you’d want to do is mess around with it. He recited an old Danish saying, whose pertinence I didn’t entirely understand but which nonetheless stuck with me. He translated it as, “Pissing in your pants will only keep you warm for so long.”
