The scorching heatwave sweeping across Pakistan and India has brought a brutal new reality to Karachi, a city once known for its sea breezes. The extreme temperatures, surpassing 44C, have transformed the city into a place where survival is a daily struggle, especially for the vulnerable populations. The impact is particularly severe in coastal settlements like Ibrahim Hyderi, where prolonged electricity outages and water shortages exacerbate the effects of the heat. Residents, including fishermen like Abdul Sattar, are battling heat exhaustion and the memories of past heatwaves that claimed lives. The healthcare system is under strain, with a surge in children visiting outpatient departments, suffering from illnesses linked to extreme heat and unsafe water. Climate experts warn that rising temperatures are no longer isolated incidents but a worsening long-term trend driven by climate change and rapid urbanisation. The World Weather Attribution group's analysis reveals that human-caused climate change has tripled the probability of such heatwaves, making them no longer exceptional. The city's humidity, shrinking tree cover, and lack of cooling centres further intensify the urban heat effect. As winters shorten and summers grow longer, harsher, and more unpredictable, the crisis is reshaping everyday life, turning extreme heat from a seasonal hardship into a persistent struggle for survival. The need for immediate intervention, including public cooling centres, expanded access to drinking water, emergency medical preparedness, and large-scale urban tree plantation drives, is now more urgent than ever.
