The world economy will record an income reduction of approximately 19% by 2049 compared to a scenario in which climate change is absent. This projection, published in the journal Nature, obtained from a model developed by the German Institute for Climate Impact Research in Potsdam.
The researchers used temperature and precipitation data from more than 1,600 regions of the world, combined with income data from the past 40 years. The Mediterranean area is considered a hotspot for climate change, where its effects are felt more pronounced, says Francesco Lamperti, of the School's Institute of Economics in Pisa. "The consequences of the climate crisis will arrive as early as 2050, therefore not in a remote future," he says. "This underlines the importance of finding adaptation policies, often left aside in public debate," he adds. The study was published in Nature, a journal of the University of California, San Diego.
