Solar Geoengineering: A Double-Edged Sword That Could Backfire Catastrophically

In a world grappling with the accelerating climate crisis, scientists are exploring increasingly bold technological solutions. Among the most controversial is solar geoengineering—a technique that could potentially cool the planet but carries risks so severe they could make our climate predicament exponentially worse.

The Promise and Peril of Playing with the Sun

Imagine a fleet of specially-designed aircraft crisscrossing the stratosphere, releasing millions of tons of sulphur dioxide aerosols that would reflect sunlight back into space, effectively dimming the sun just enough to cool Earth’s fever. This isn’t science fiction—it’s the concept behind solar radiation modification (SRM), and it’s being seriously studied by researchers worldwide.

But here’s the terrifying catch: if this delicate climate intervention were suddenly halted, the consequences could be catastrophic.

The “Termination Shock” Nobody’s Talking About

New research from the National Autonomous University of Mexico, published in a groundbreaking study, reveals a chilling reality. If solar geoengineering were abruptly stopped—whether due to political upheaval, technological failure, or international conflict—the planet would experience what scientists call “termination shock.”

Picture this: temperatures that had been artificially suppressed would rebound at an alarming rate. The study found that if aerosol injection began in 2020 and was suddenly terminated in 2030, global temperatures could spike by 0.6°C over just eight years. To put that in perspective, that’s roughly the amount of warming the planet has experienced over the past century—compressed into less than a decade.

The Economic Nightmare Scenario

The financial implications are staggering. The Mexican research team calculated that unmitigated climate change could cause $868 billion in economic damages by 2100. Solar geoengineering that successfully limited warming could cut those damages in half. But if termination shock occurred, damages could skyrocket past $1 trillion.

As lead researcher Francisco Estrada puts it: “It would be much worse if we have a termination shock than if we did nothing, if we had unabated climate change.”

The Governance Paradox

Here’s where it gets really interesting—and concerning. The study reveals what Estrada calls the “governance paradox” of solar geoengineering. For SRM to work safely, we’d need:

• Near-perfect international cooperation lasting centuries
• Fail-safe systems to prevent sudden termination
• Robust governance structures for both geoengineering and emissions reduction

But if we had that level of global cooperation and governance capability, we wouldn’t actually need solar geoengineering in the first place. We’d already be solving the climate crisis through emissions reductions.

Silicon Valley Races Ahead

Meanwhile, in the real world, private companies aren’t waiting for international consensus. Make Sunsets, a Silicon Valley startup, has already launched over 200 balloons carrying sulphur dioxide into the stratosphere—selling “cooling credits” to individuals and companies looking to offset their emissions.

The company’s activities in Mexico prompted that country’s government to threaten a complete ban on geoengineering. Another company, Stardust, has raised $75 million and is actively lobbying the U.S. government about solar geoengineering deployment.

The Scale Problem

Cooling Earth by just 1°C would require at least 100 aircraft continuously dispersing millions of tons of sulphur dioxide into the stratosphere—every single year, without interruption, for centuries. That’s not a one-time solution; it’s a permanent commitment.

And that’s assuming perfect conditions. Factor in potential wars, pandemics, political upheavals, or economic crises, and the risk of termination shock becomes even more concerning.

What Scientists Really Think

A survey conducted by New Scientist last year found that two-thirds of climate scientists expect large-scale solar radiation modification to be attempted this century. But there’s a crucial distinction between expecting something to happen and endorsing it.

The new research suggests that scientists studying geoengineering aren’t necessarily pushing for its deployment. Instead, they’re trying to understand the full implications—both good and bad—of what might become humanity’s most controversial climate intervention yet.

The Bottom Line

Solar geoengineering represents a technological Hail Mary pass in the face of climate catastrophe. It could work, potentially buying us crucial time to reduce emissions and adapt to a warming world. But it could also backfire spectacularly, creating a climate crisis far worse than the one we’re trying to solve.

As emissions continue to rise and climate impacts intensify, the debate over solar geoengineering will only grow more heated. The question isn’t just whether we can do it—it’s whether we should, knowing the risks of getting it wrong could be catastrophic.
