Andreas Malm, a climate activist and senior lecturer at Lund University, in Sweden, studies the relationship between climate change and capitalism. With the United Nations climate meeting in Glasgow rapidly approaching—it begins on October 31st—Malm tells David Remnick that he believes environmentalists should not place too much faith in talks or treaties of this kind. Instead, he insists that the climate movement rethink its roots in nonviolence. His book is provocatively titled “How To Blow Up A Pipeline,” though it is not exactly an instruction manual. Malm advocates for “intelligent sabotage” of fossil-fuel infrastructure to prevent more carbon from being emitted in the atmosphere. “I am in favor of destroying machines, property—not harming people. That’s a very important distinction,” he tells Remnick.
