TIME TO FACE THE HEAT
All living things share one simple fate: if the temperature they’re used to rises too high too fast, they’ll die. Jeff Goodell talks to Bron Sibree about his propulsive new book

There is no going back to normal. We have crossed over into a new climate, a new reality
hen heat comes, it’s invisible. It doesn’t bend tree branches or blow hair across your face to let you know it’s arrived. With these words, award-winning US journalist Jeff Goodell begins his latest book, The Heat Will Kill You First: Life and Death on a Scorched Planet.
Goodell, a contributing editor for
Rolling Stone magazine who’s been writing about climate change for 22 years, is the author of six previous acclaimed books, including The Water Will Come: Rising Seas, Sinking Cities and the Remaking of the Civilised World, which was a New York Times Critics’ Top Book of 2017. Heat is Goodell’s seventh work of non-fiction and is already a New York Times best-seller. It’s arguably also one of the most eloquent books — and one of the most terrifying — to hit the global bookshelf.
Goodell’s goal in writing it is to convince us to think about heat differently. And he has traversed the globe to show just how heat is the first-order effect of the climate crisis, the very engine of planetary chaos. Yet, he insists, “if you’d asked me what heat was 15 years ago, I couldn’t have told you”. He came to think about heat differently on a very hot day five years ago in Phoenix, Arizona. “I had to walk downtown to a meeting, and my heart started pounding and after 15 blocks I was feeling dizzy, and it just occurred to me that heat is not just a number on a thermometer — it’s a lethal force that can kill you. And that was the ‘aha’ moment where the book began.”
As he reveals in Heat, there is no escaping that we are now more than halfway to 2°C of warming from preindustrial temperatures, which, he writes, “scientists have long warned is the threshold for dangerous climate change”. Yet, as he emphasises to me now, “the term ‘global warming’ is one that is profoundly mismatched with the reality of its meaning”. He says: “Obviously, if you understand the science, you think differently about it. But to the average person, when you say a phrase like ‘global warming’ or talk about the temperature rising by 1-2°C, it doesn’t sound so bad. So it’s not surprising that a lot of people don’t grasp what the implications are for our rapidly warming world.”
Early on in this propulsive book, he drives home just how deadly not grasping those implications can be. In its first chapter, he tells the story of a young, fit, outdoorsy couple who’d traded city life for a house in the foothills of California’s Sierra Nevada valley during the pandemic. Ignoring heat warnings, they set out early one morning on a hot day with their oneyear-old daughter and their dog for a 13km hike to the Merced River and back. A search party found them all dead on the trail days later. Their deaths initially puzzled authorities, says Goodell. “But after about a month of investigation, they realised they had all died of heatstroke. And I wanted to tell this tale because it underscores that everyone is vulnerable, even young people in good shape.”
The couple’s dog, he notes, likely got into trouble first. Unlike humans, dogs cannot sweat and are therefore vulnerable to heat. He goes on to delve into the science, not only of heatstroke and heat exhaustion, detailing their effects on the body, but also the history and science of evolution to explain how human bodies developed the mechanism — sweat — that allows us to deal with hot weather. Along the way, the reader also learns how elephants, camels and bees, to name just a few animals, cope with heat. Because as he writes in Heat, all living things share one simple fate: if the temperature they’re used to — what scientists sometimes call their “Goldilocks Zone ”— rises too high too fast, they’ll die.
Along with descriptions of salmon boiling in rivers and bumble bees falling out of the sky in recent heatwaves, Goodell writes potently about the cascading effects of a warming planet on all living things: “Whether it’s the salmon in the creeks and rivers, the oak trees or bats or frogs, they all have to migrate to cooler places or die.”
He devotes an entire chapter to the many microbes and their unwanted vectors that are also trying to seek out their Goldilocks Zone. “As the climate warms up, they’re moving to new places, and that’s having huge implications in Africa, as mosquitoes that carry malaria move to new places. We’re seeing the first emergence of malaria in the southern US in many decades, while dengue fever and the Zika virus are emerging in new places such as Mexico City.”
Whether it’s the dire implications of the looming “great migration ”— human or otherwise — or those of an oceanic heatwave known as “the blob”, the rapid melting of ice sheets in West Antarctica, the plight of outdoor workers everywhere
— be it in India, Qatar or the US — or the complex, divisive legacy of airconditioning, there’s no vital issue, it seems, that Goodell doesn’t illuminate in this book. Indeed, the extraordinary power of Goodell’s narrative is the way he renders cutting-edge science understandable, adroitly interweaving scientific detail, relevant statistics and conversations with scientists with the stories of ordinary individuals to drive home the invisible power of “this form of heat that has been unleashed upon us through the burning of fossil fuels”.
The tragedy of the climate crisis, says Goodell, “is that not only have scientists understood the implications of burning fossil fuels for decades, but the fossil fuel companies themselves have known this for decades also”. He continues: “But even if we cut using fossil fuels tomorrow — which, of course, we are not going to do — we will not go back to having a climate that resembles the one we all grew up in. There is no going back to normal. We have crossed over into a new climate, a new reality. Until we get to net zero, the temperature will continue to rise, and when we do get to net zero, that will stabilise the temperatures at where they are now — but it will not bring them back to what they were 50 years ago.”
Yet he insists it is not beyond our reach to make the difficult, necessary changes to prevent us all from crossing the silent borders of the Goldilocks Zone. But it will, he writes, “require political leadership and a deeper understanding of our connection with one another and with the world we live in”.
Should we fail to do this and pass out of that zone, he argues, “it will change the dynamics of life on this planet in a big way”. However, he says: “It is not about being too late. There is no ‘too late’. There is only better and worse. But every tonne of CO2 that we keep out of the atmosphere is a step in the right direction.”
