![]() ![]() In fact in some cases it's just the opposite," said University of Cambridge macro-economist Kaimar Mohaddes. "It's not the case that all countries suffer from an El Nino. Economists who looked at their study were not impressed, but other climate scientists were. Neither Mankin nor Callahan are full-time economists. "Our economies are poorly adjusted and poorly adapted to the climate variability that we have right now," Mankin said. And it shows a world unprepared for the hurt that's coming, he said. The last strong El Nino was in 2016.īecause "the impacts of El Nino look a lot like the impacts of global warming," studying the El Nino economic damage "is pretty essential" to understanding the bigger damage from human-caused climate change, Mankin said. National Oceanic and Atmospheric Administration. It's warmer in much of Asia, the American Pacific Northwest and Australia.Įl Ninos occur on average about every three to five years and vary in strength, according to the U.S. It makes it drier in southeast Africa, southern Asia, northern Australia and the Amazon and often leads to increased wildfires in those areas. South and West, Peru, Uruguay and Argentina, some of Southeast Asia, and a bit of east central Africa. It makes it wetter across much of the U.S. The World Bank estimated the 1997-1998 El Nino cost governments $45 billion, which is more than 100 times smaller than the Dartmouth estimate.īut the Dartmouth team said they are looking at more than the traditional costs and for longer time periods.Įl Nino's biggest impacts generally hit in the northern winter, but in the summer it reduces hurricane activity in the Atlantic, studies show. The strong 1997-1998 one cost $5.7 trillion. Study authors said the average El Nino costs the global economy about $3.4 trillion. And some - but not all - outside economists have issues with the new research out of Dartmouth College, saying its damage estimates are too big. It runs counter to previous research that found, at least in the United States, that El Ninos overall aren't too costly and can even be beneficial. The study in Thursday's journal Science totals global damage with an emphasis on lasting economic scars. It also adds an extra boost to human-caused warming. El Nino is a temporary and natural warming of parts of the equatorial Pacific, that causes droughts, floods and heat waves in different parts of the world. WASHINGTON (AP) - The natural burst of El Nino warming that changes weather worldwide is far costlier with longer-lasting expenses than experts had thought, averaging trillions of dollars in damage, a new study found.Īn El Nino is brewing now and it might be a big - and therefore costly - one, scientists said. ![]()
