A recent study commissioned by the charity WaterAid has revealed that cities around the world are experiencing extreme weather fluctuations due to rising temperatures disrupting the global water cycle. The study, based on 42 years of weather data from over 100 major cities, found that South and Southeast Asia are becoming wetter, while Europe, the Middle East, and North Africa are getting drier.
Lead researcher Michael Singer from Cardiff University’s Water Research Institute expressed concern about the impact of climate change, stating that there will be winners and losers. Some cities, such as Hangzhou in China and Jakarta in Indonesia, are facing “climate whiplash” with severe floods and droughts occurring in rapid succession. Additionally, cities like Dallas, Shanghai, and Baghdad are experiencing simultaneous increases in flood and drought risks.
Singer emphasized the importance of recognizing that different regions will respond differently to climate change, regardless of their wealth or infrastructure. Cities like Hangzhou, which witnessed record high temperatures and severe flooding, highlight the urgent need for adaptation measures.
The study also noted that cities such as Colombo, Mumbai, Cairo, and Hong Kong are experiencing shifts towards either increased wetness or dryness, necessitating infrastructure adjustments. Singer warned that cities must prepare for changing climate conditions and invest in adaptation strategies.
While some cities, such as Tokyo, London, and Guangzhou, have seen more stable weather patterns in recent years, the overall trend indicates a challenging future for urban areas worldwide. The study underscores the urgency for cities to address the impacts of climate change and implement resilient solutions.
