IMD Warns of Extended Heatwave in Northwest India Amid Climate Change Concerns

The India Meteorological Department (IMD) has issued a heatwave warning for northwest India, including states like Punjab, Haryana, Delhi, and parts of Rajasthan. The alert indicates that the region will experience above-normal temperatures, with the possibility of heatwave conditions continuing for the next five days. This prolonged heat is attributed to a combination of natural phenomena and the escalating impacts of climate change.​

According to the IMD, temperatures in the affected areas are expected to rise by 2 to 3 degrees Celsius above the normal range. The department has issued a "red" warning for Delhi, Haryana, Punjab, and western Rajasthan, advising extreme caution, especially for vulnerable populations. The heatwave is anticipated to persist for at least five days, with temperatures soaring to 47.4°C in areas like Najafgarh in Delhi and 47.1°C in Sirsa, Haryana.

Experts suggest that this intense heat is a result of the El Niño phenomenon, characterized by the unusual warming of ocean surfaces in the central and eastern tropical Pacific Ocean. Additionally, rapid urbanization and industrialization have exacerbated the warming in urban areas, leading to more frequent and severe heatwaves.

The prolonged heat has significant implications for public health, agriculture, and energy consumption. In 2024, India recorded nearly 25,000 suspected heatstroke cases and 56 deaths due to heat-related illnesses from March to May. The intense heat has also driven India's power demand to a record 246 gigawatts, as air conditioners and coolers run at full capacity. ​

The IMD's forecast indicates that northwest India may experience nearly double the usual number of heatwave days this year. Typically, the region records five to six heatwave days in a season, but this year, it is likely to experience 10 to 12 days. ​

Conclusion:

As northwest India braces for an extended heatwave, it is crucial for residents to take necessary precautions to safeguard their health and well-being. The increasing frequency and intensity of heatwaves underscore the urgent need for comprehensive climate action to mitigate the impacts of climate change. This includes reducing greenhouse gas emissions, promoting sustainable urban planning, and enhancing public awareness about climate-related risks.
