A recent study has revealed a concerning trend of increasing extremely hot days in the world's largest capital cities, driven by rising temperatures across Asia amidst the worsening climate crisis. The analysis conducted by the International Institute for Environment and Development (IIED) found that the 20 most populous cities globally have experienced a 52% surge in days surpassing 35 degrees Celsius over the past three decades.
The impact of human-caused greenhouse gas emissions is evident as major capital cities, from Buenos Aires to Paris and Cairo, are facing more frequent extreme heat days with each passing decade. The phenomenon is exacerbated by the urban heat island effect, where cities, through extensive infrastructure, retain more heat compared to natural landscapes.
