Unbearable heat in India becoming a major threat to health

In India, summer heat could soon be unbearable — literally

An analysis of South Asia’s biggest cities found that if current warming trends continued, wet bulb temperatures — a measure of heat and humidity indicating when the body can no longer cool itself — will become so high people directly exposed for six hours or more would die.

NEW DELHI — On a sweltering Wednesday in June, a rail-thin woman named Rehmati gripped the doctor’s table with both hands. She could hardly hold herself upright, the pain in her stomach was so intense.

She had traveled for 26 hours in a hot oven of a bus to visit her husband, a migrant worker here in the Indian capital. By the time she got here, the city was an oven, too: 111 degrees by lunchtime, and Rehmati was in an emergency room.

The doctor, Reena Yadav, did not know exactly what had made Rehmati sick, but it was clearly linked to the heat. Yadav suspected dehydration, possibly aggravated by fasting during Ramadan. Or it could have been food poisoning, common in summer because food spoils quickly.

Yadav put Rehmati, who is 31 and goes by one name, on a drip. She held her hand and told her she would be fine. Rehmati leaned over and retched.

Extreme heat can kill, as it did by the dozens in Pakistan in May. But as many of South Asia’s already-scorching cities get even hotter, scientists and economists are warning of a quieter, more far-reaching danger: Extreme heat is devastating the health and livelihoods of tens of millions more.

If global greenhouse-gas emissions continue at their current pace, they say, heat and humidity levels could become unbearable, especially for the poor.

It is already making them poorer and sicker.

…….Indeed, a recent analysis of climate trends in several of South Asia’s biggest cities found that if current warming trends continue, by the end of the century, wet bulb temperatures — a measure of heat and humidity that can indicate the point when the body can no longer cool itself — would be so high that people directly exposed for six hours or more would not survive.

In many places, heat only magnifies the more thorny urban problems, including a shortage of basic services, like electricity and water.

…The science is unequivocally worrying. Across the region, a recent World Bank report concluded, rising temperatures could diminish the living standards of 800 million people.

Worldwide, among the 100 most populous cities where summer highs are expected to reach at least 95 degrees Fahrenheit by 2050, according to estimates by the Urban Climate Change Research Network, 24 are in India.

………Delhi’s heat index, a metric that takes average temperatures and relative humidity into account, has risen sharply — by 0.6 degrees Celsius in summer and 0.55 degrees during monsoons per decade between 1951 and 2010, according to one analysis based on data from 283 weather stations across the country.

Some cities are getting hotter at different times of year. The average March-to-May summertime heat index for Hyderabad had risen by 0.69 degrees per decade between 1951 and 2010. In Kolkata, a delta city in the east, where summers are sticky and hot anyway, the monsoon is becoming particularly harsh: The city’s June-September heat index climbed by 0.26 degrees Celsius per decade.

Joyashree Roy, an economist at Jadavpur University in Kolkata, found that already, most days in the summer are too hot and humid to be doing heavy physical labor without protection, with wet-bulb temperatures far exceeding the thresholds of most international occupational health standards. of most international occupational health standards……… https://www.seattletimes.com/nation-world/in-india-summer-heat-could-soon-be-unbearable-literally/
