In 2015, 195 countries gathered in Paris to discuss how to address the climate crisis. Although there was plenty they couldn’t agree on, there was one point of near-absolute consensus: if the planet becomes 2°C hotter than it was before industrialization, the effects will be catastrophic. Despite that consensus, we have continued barrelling toward that 2°C threshold. And while the world is finally paying attention to climate change, the pace of our action is radically out of step with the severity of the problem. What is becoming increasingly clear is that just cutting our emissions – by switching to clean energy or driving electric cars – will not be sufficient. We will also need some bold technological solutions if we want to maintain some semblance of life as we know it.

Luckily, everything is on the table. Grinding entire mountains into powder and dumping them into oceans. Sucking carbon directly out of the air and burying it underground. Spraying millions of tons of sulphur dioxide directly into the atmosphere.

Gwynne Dyer has spent the past four years interviewing the world’s leading climate scientists about the moonshots that could save the planet. Dyer is a journalist and historian who has written a dozen books over his career, and has become one of Canada’s most trusted commentators on war and geopolitics.

But his latest book, Intervention Earth, is about the battle to save the planet.

Like any reporting on the climate, it’s inevitably a little depressing. But with this book Dyer has also given us a different way of thinking about the climate crisis – and maybe even a road map for how technology could help us avoid our own destruction.
