Let the wind do the work of capturing carbon.

Watch her. A polar bear, three days in open water, swimming through a sea that was ice within her own lifetime.1 Her kind spent hundreds of thousands of years mastering the frozen ocean3 — and in a handful of decades, we have melted the ground from under her. Somewhere ahead, she trusts, there is an ice-floe that will bear her weight. More and more often, there is only water, and she swims until she can swim no more. The longest recorded swim is nine days and 687 kilometres; that bear reached the ice having lost a fifth of her body, and her cub did not reach it at all.2 Nearly half the mothers tracked on such swims lost their young to the open sea.1 The cubs drown. The mothers that make it ashore are often too spent to hunt, and starve.

At the far end of the Earth, an emperor penguin chick stands where ten thousand generations stood before it, on ice that was meant to hold until it had grown its waterproof feathers. The ice no longer keeps its promise. In the spring of 2022 it broke up beneath four of the five colonies of the Bellingshausen Sea, weeks before a single chick had fledged. They dropped through into the water they were born to command — and they drowned, or froze, in their thousands. Not one is believed to have survived.4 Nearly a third of all known emperor colonies have now been struck by early ice loss, and the emperors of that region have declined by more than a fifth in fourteen years — faster than the worst models predicted.5

Do not mistake this for misfortune. This is the web of life being unpicked, thread by thread — and it is our hands pulling the threads. Even the ocean itself, the great patient ally that has swallowed more of the carbon we drill, pump and burn from oil and gas than every forest on Earth combined,6 is turning acid in silence. In the Southern Ocean and along the Pacific coast, the shells of the sea butterflies — the tiny swimming snails at the very base of the food web — are being eaten away while the animals inside them are still alive.7 Off California, the share of them dissolving has already doubled since the industrial age began, and is on course to triple.8 When the base of the web dissolves, everything built upon it goes hungry: the fish, the whales, the seabirds — and, in time, us. We are a strand in that same web. What we unravel, unravels us.

And in the frozen ground of Siberia, something older than any forest is beginning to stir. For thirty years, from a lonely research station on the Kolyma River, the Russian geophysicist Sergey Zimov has warned anyone who would listen that the permafrost is not merely ice. It is the deep-frozen remains of a vanished world — the grasses and beasts of the mammoth steppe, layered twenty-five metres deep across a million square kilometres.10 Frozen, it is harmless. Thawed, the microbes wake and breathe it out as carbon dioxide and methane. The Arctic permafrost holds roughly twice the carbon of the entire atmosphere — more than three times everything humanity has ever released from oil, gas and coal.11 Zimov once stripped the moss from a patch of ground near his station to show what comes next: within a decade it had collapsed into pits three metres deep, exhaling as it went. “This is the future we are facing,” he says, “if we cannot stabilize the permafrost.”10 The thaw has begun, and it does not negotiate. Which is why merely cutting what we emit will never be enough. The carbon already loosed must be drawn back down.

None of this is mystery. We drill oil and gas a hundred million years old out of the ground and hand their carbon to the sky faster than the living world can ever take it back. In 2025, we burned more of it than in any year in human history — and that tide is still rising.9
