Is 'Polycrisis' a Useful Term for Understanding the World Today?

Today we are once again beset by seemingly unconnected crises. Such as the war in Ukraine, the climate crisis and the aftermath of COVID-19. "So economics, politics, geopolitics and then the natural environment blowing back at us – and those 4 things, they don’t reduce to a single common denominator. They don’t reduce to a single factor. And that's why I think the polycrisis term has a real utility descriptively as much as anything else, because it's kind of hand-waving, of course, it's kind of arm waving. It's going, look, there's a lot of stuff happening here all at once. And that precisely is what we're trying to wrap our minds around."
