Guess What Else Climate Change Hurts? Globalization

When weather catastrophes hit, the big-ticket damages tend to come not from heat waves but from floods, hurricanes, and wildfires. Natural disasters caused billions of dollars in damagelast month alone, according to a recent report, from Canadian wildfires ($3.1 billion), to European flooding ($4.6 billion), to U.S. storm damage ($1 billion).

Imported materials may remain unfinished, even after they’re exported to the next station on the international assembly line. This “vertical specialization,” it turns out, may have a blind spot when it comes to climate change, according to new research from the Potsdam Institute for Climate Impact Research. Manufacturing is only as strong as the weakest, or in this case hottest, link in the supply chain.
