An exploration of the devastating effects of global warming—current and future—adapted for young adults from the #1 New York Times bestseller. This is not only an assessment on how the future will look to those living through it, but also a dire overview and an impassioned and hopeful call to action to change the trajectory while there is still time. The climate crisis that our nation currently faces, from rising temperatures, unfathomable drought, devastating floods, unprecedented fires, just to name a few, are alarming precursors to what awaits us if we continue on our current path. In this adaptation for young adults from the #1 New York Times bestseller, journalist David Wallace-Wells tells it like it is, and it is much worse than anyone might think. Global warming is effecting the world, if left unchecked, it promises to transform global politics, the meaning of technology and the trajectory of human progress. In sobering detail, Wallace-Wells lays out the mistakes and inaction of past and current generations that we see negatively affecting all lives today and more importantly how they will inevitably affect the future. But readers will also hear—loud and clear—his impassioned call to action, as he appeals to current and future generations, especially young people. As he states: “the solutions, when we dare to imagine them . . . are indeed motivating, if there is to be any chance of preserving even the hope for a happier future—relatively livable, relatively fulfilling, relatively prosperous, and perhaps more than only relatively just.” David Wallace-Wells is a columnist and deputy editor at New York magazine. He has been a national fellow at the New America Foundation and was previously the deputy editor of The Paris Review . He lives in New York City. The world will be what we make it--perhaps what you make it. The timelines are indeed that short. Consider the speed of change. The earth has experienced five mass extinctions before the one we are living through now, each so complete a wiping of the fossil record that it functioned as an evolutionary reset, the planet’s phylogenetic tree first expanding, then collapsing, at intervals, like a lung: 86 percent of all species dead 450 million years ago; 70 million years later, 75 percent; 125 million years later, 96 percent; 50 million years later, 80 percent; 135 million years after that, 75 percent again. All but one of these involved climate change produced by greenhouse gas. The most notorious was 250 million years ago; it began when carbon dioxide warmed the planet by five degrees Celsius, accelerated when that warming triggered the release of methane, another greenhouse gas, and ended with all but a sliver of life on Earth dead. We are currently adding carbon to the atmosphere at a considerably faster rate--by most estimates, at least ten times faster. The rate is one hundred times faster than at any point in human history before the beginning of industrialization. And there is already, right now, fully a third more carbon in the atmosphere than at any point in the last 800,000 years--perhaps in as long as 15 million years. There were no humans then. The oceans were more than a hundred feet higher. Many perceive global warming as a sort of moral and economic debt, accumulated since the beginning of the Industrial Revolution and now come due after several centuries. In fact, more than half the carbon exhaled into the atmosphere by the burning of fossil fuels has been emitted in just the past three decades. The United Nations established its climate change framework in 1992, building a political consensus out of a scientific consensus and advertising it unmistakably to the world; this means we have now done as much damage to the environment knowingly as we ever managed in ignorance. Global warming may seem like a distended morality tale playing out over several centuries and inflicting a kind of Old Testament retribution on the great-great-grandchildren of those responsible, since it was carbon burning in eighteenth-century England that lit the fuse of everything that has followed. But that is a fable about historical villainy that acquits those of us alive today--unfairly. The majority of the burning has come since the 1994 premiere of Friends. A quarter of the damage has been done since Barack Obama was elected president, and Joe Biden vice president, in 2008. Since the end of World War II, the figure is about 90 percent. The story of the industrial world’s kamikaze mission is the story of a single lifetime--the planet brought from seeming stability to the brink of catastrophe in the years between a baptism or bar mitzvah and a funeral. It is the lifetime of many of the scientists who first raised public alarm about climate change, some of whom, incredibly, remain working--that is how rapidly we have arrived at this promontory, staring down the likelihood of three degrees Celsius of warming by the year 2100. Four degrees is possible
