How does El Nio, a well-known storm system, affect the world economy? This is what a recent study that was just published in the journal Science aims to comprehend as a pair of academics investigate the long-term financial effects of El Nio, which might endure for years and result in trillions of dollars in lost income throughout the world. This investigation is being conducted as El Nio is anticipated to return this year. The legendary storm system’s total financial losses have been assessed by earlier studies, but this most recent analysis is the first of its type to analyze the long-term financial and project losses, which far exceed those earlier projections.A color scale from the greatest increase (blue) to the largest drop (red) shows the percentage change in the gross domestic product following the 1997–1998 El Nio.
