Heat Wave: The Center of Science and Environment recently examined the temperature indices of Delhi, Mumbai, Hyderabad, Bangalore, and Chennai for their research, "Decoding the Urban Heat Stress Among Indian Cities." The nighttime lows in these cities are lower than they were between 2001 and 2010.
In most of the nation, extreme heat is still causing damage. In Delhi, the capital of the country, it is pouring with fire. The fact that the temperature here surpassed 48 degrees on Monday provides an indication of the situation. Rajasthan is experiencing the deadliest heat of the season. Here, the temperature was higher than 49 degrees. In addition, temperatures in many areas of Punjab, Haryana, Uttar Pradesh, and Madhya Pradesh exceeded 48 degrees. In several of the nation's major cities, the nights are growing hotter during the summer. The degree of heat Since 2010, there has been a noticeable rise in the country's major metro areas' index (HI). The primary causes of this include the fast growing urban construction industry, climate change, and rising air humidity. The urban temperature index has risen for all of these causes. Concurrently, the air in cities is becoming hotter due to the growing usage of air conditioners.
The temperature indices of Delhi, Mumbai, Hyderabad, Bangalore, and Chennai were recently examined for a research published by the Center of Science and Environment titled "Decoding the Urban Heat Stress Among Indian Cities." The nighttime lows in these cities are lower than they were between 2001 and 2010. The paper claims that the land surface temperature used to drop by 6.2 to 13.2 degrees Celsius at night, based on data spanning a decade. However, in the It has barely dropped by 6.2 degrees Celsius to 11.5 degrees Celsius over the past ten summers. Mumbai has experienced the largest drop in nighttime cold, of 24 percent. There is a clear correlation between human health and a decrease in nighttime cold. People consequently have very little time to recuperate from the tension brought on by the day's heat.
The chance of dying from exceptionally hot nights will increase by around six times, according to this story, which cites a study done by a consortium of scientists from China, South Korea, Japan, Germany, and the US and published in the Lancet Planetary Health. According to the survey, even during the monsoon, the temperatures in Delhi, Mumbai, Kolkata, and Chennai are rising. There has been more heat than there was before the monsoon. In Delhi and Mumbai, the heat index increased during the monsoon season from 2001 to 2010. additionally Kolkata, but it was inside the metropolitan areas of Hyderabad, Bengaluru, and Chennai in South India. However, over the past ten years, the monsoon season has increased hotter in Delhi, Mumbai, and Kolkata. Simultaneously, Chennai has lost the mild coolness that was present throughout the monsoon. In fact, when humidity is taken into account together with temperature, the temperature index indicates the real amount of heat felt. An index of heat of 41 degrees Celsius is thought to be harmful to human health.
The 24-hour high temperature index, according to the paper, also puts more strain on the power supply. The power load is increased by overusing refrigerators, air conditioners, and coolers. When cooling equipment is used excessively, the temperature in that region rises. According to the research, cities' air is becoming hotter due to the growing usage of air conditioners. A number of states, such as Maharashtra, Uttar Pradesh, and Delhi, have set new records for the demand for power.
