An international team that included two researchers from the University of Hawaii in Manoa, using machine learning found that human-made carbon dioxide emissions and climate change have already caused an increase in daily rainfall variability in the tropical eastern Pacific and central ocean. latitudes. The study was published in Nature . "Climate model projections suggest that warming will intensify precipitation variability and extremes such as heavy rains and droughts in many areas of the world," said Malte Stuecker, study co-author and assistant professor at the UH Manoa School of Ocean and Earth.. Science and technology (SOEST). "However, whether these anthropogenic trends are already visible in current precipitation observations has remained a major challenge due to large natural fluctuations in precipitation at regional scales."
