Hey, it's Flora, and you're listening to Science Friday.
How extreme is the recent heat in India and which cities were hardest hit?
India is one of the most climate-vulnerable countries in the world, and weather disasters like heat waves have become more extreme and more common in recent years. At one point this year, the 50 hottest cities on the planet were all in India. The average peak temperature in those cities was 112 degrees Fahrenheit. So how is this extreme heat affecting people in India and what needs to change to keep people safe? My next guest has some answers. Dr. Gulrez Azhar is a physician and researcher who has spent much of his career studying the health impacts of heat waves in India. Gulrez, welcome to Science Friday.
Thank you so much.
I want to hear a little bit about how you got into this field.
How did Dr. Gulrez Azhar's background lead him to study heat and health in India?
Would you tell me a little bit about how you grew up?
I grew up in a state called Uttar Pradesh, which is the largest state by population in the country. It's in the northern part of the country. It's among these, I think, the second poorest state in the country. Per capita income somewhere around a thousand dollars per person per year. Then went to did my med school and residency training in community medicine, which meant I was working out and was exposed to poverty. far more of the rural life or the urban slum communities or mobile health clinics in hard to reach areas. So that was my exposure, both as someone who was born there, grew up there, and then my medical residency training in that state.
And why did heat capture your attention?
After my residency training, I went to study public health in Europe. And of course, it's a contrast, huge contrast from the hinterland of India. And there are things I noticed that, for example, European households didn't have air conditioning, they didn't have really fans. And there was this historical discussion, you know, about heating. the heatwave in Europe, which has happened before and had apparently killed 70,000 people there. I think it was 2003. And coming back to India, I was posted in another state on the western part of the country.
What evidence showed heat waves were causing excess deaths in Indian cities?
And that state was hot and hotter than the state I grew up in. I asked about the winter season when it's going to come, and they said there are only two seasons here. It's either hot or it's very, very hot. And so you are in the hot season, which meant the winter season.
Mild relative to the very, very hot season.
Mild season.
And, you know, you start to think that if compared to Europe, which was cold, if this in winter was so unsufferable, uncomfortable, then what was going on in summer? And if in Europe, mild Europe, it had 70,000 documented deaths in places which are less densely populated, well, they have better health care systems and are not as hot. So then what's going on in India? So we went and looked into the data which we have. And admittedly, data in our parts of the world are not very accurate or complete. But we still had orders of magnitude, I think 1,300 excess deaths in that month. And I think more than 300 excess deaths per day.
And this is just one city, right?
Why are official heat-related death counts in India unreliable?
Just one city, just one, two, three day heatwave period. So that was completely eye-opening. And before that, there was this assumption that, you know, people are somehow used to it. And, you know, India is always hot. I mean, it is true to some degree. But at the same time, there are certain limits to human adaptation, human physiological threshold. There are those hard limits, which we as humans just cannot. And we notice that temperatures... even right now and in future are projected to exceed those human survival thresholds. So what would happen to places? And it's already to some degree gradually happening. And we are seeing that especially like people who are working in service based industries, even agriculture, construction, laborers, people who are forced to spend time outside, don't have access to air conditioning.
And that's huge. Access to air conditioning in India is in single digits all over the country. So Single digits. Single digits. More than 94% of people do not have access to an air conditioner at home.
