Not to be confused with a “perfect storm” or the perhaps less scientific “clusterfuck”, “polycrisis” – a term coined by the authors Edgar Morin and Anne Brigitte Kern – refers to the idea that not only are we facing one disaster after another, but those messes are all linked, making things even worse. Or, as Adam Tooze, a Columbia University history professor and public intellectual who has championed the term, put it: “In the polycrisis the shocks are disparate, but they interact so that the whole is even more overwhelming than the sum of the parts.”
