The heavy rains that flooded Dubai this week halted air traffic, damaged buildings and streets – and left climate experts and common citizens asking whether one of the world’s hottest and driest cities should be better prepared for extreme storms.Weather forecasters knew days in advance that a major storm was heading for the United Arab Emirates and authorities issued warnings asking citizens to stay home. Yet its largest city Dubai was still brought to a halt this week, with one of the worst rain events in decades flooding streets, homes and highways. “Stormwater management systems were historically deemed an ‘unnecessary cost’ due to the limited rainfall” in the UAE, said Karim Elgendy, an associate fellow at the Environment and Society Centre at Chatham House. “As the variability of rainfall increases across the region and as the likelihood of such events rises, the economic case for such systems becomes stronger.”
