Extreme weather events like super-typhoon Haiyan and hurricane Sandy can have major negative impacts on the world economy. So far, however, the effects on global production and consumption webs are missing from most assessments. This is a serious deficit, argues Anders Levermann from the Potsdam Institute for Climate Impact Research: "World markets as well as local economies are highly interlinked and rely on global supply chains—adaptation therefore requires a global perspective, not just a local one."
