In some of the world’s most densely populated cities, the weather is swinging from drought to floods and is coming back again because rising temperatures play havoc with the global water cycle, a study done by the charity. Waterd Shown on Wednesday.
South and South -East Asia face the strongest wet trends, while Europe, the Middle East and North Africa are ever drying up, researchers found in a study of 42 years of weather figures prepared from cities with more than 100 population of the world.
“Climate change will be the winners and losers,” said Michael Singer of Water Research Institute at Cardiff University, one of the authors of the study. “This is already happening.”
The study showed that China’s eastern city of Hangzau and Indonesia’s capital Jakarta, the capital of Jakarta, is at the top of the list of cities suffering from the “Climate Whiplash”, or long -term succession of floods and droughts.
15% of the surveyed cities were also facing the worst of both the world, with excessive floods and dried risks at the same time, among them the Chinese commercial centers of Texon city Dallas, Shanghai and Baghdad, the capital of Iraq, the capital of Iraq.
“You can’t just assume that atmospheric warming may have a response,” the singer said. “It doesn’t care who you are, whether you are rich or poor or you have a great infrastructure or not.”
China’s coastal city of Hangzau had set a record with an extreme high temperature of 60 days last year, and was also killed by severe floods that forced the thousands to evacuate.
The fifth cities have seen a reversal in climate extremes, with the Sri Lankan capital of Colombo and the Indian financial centers of Mumbai “Flipping”, while the Egyptian capital of Cairo and Hong Kong is constantly dried up.
Many cities that build infrastructure, they are now facing completely different circumstances to either maximize rare water supply or to reduce flood loss, and will need to invest to adapt it, the singer warned.
Some people who experience favorable changes include the Japanese capital of Tokyo, London and Southern Guangzhou in China, with a quite wet and dry months compared to two pre -decades in the period from 2002 to 2023.
