India heatwaves raise fears of future climate impacts

Extreme heat has claimed many lives in India this year, and scientists say it can only get worse
Large numbers of people die in India each year because of heat waves − and as climate change takes hold and the country swelters again, doctors are warning the public to take extra precautions
India is sizzling under hot winds as many parts of the country suffer temperatures hovering above 40C.
Officials in the National Weather Forecasting Center of the India Metrological Department have warned that “heat waves to severe heat wave conditions would prevail in isolated parts of the country in the last week of May”.
As the latest Intergovernmental Panel on Climate Change (IPCC) reports confirm that India will continue to get hotter because of climate change, doctors are concerned that the public needs to be warned of the danger they are in.
Kumar Srinivasan, a 34-year-old policeman, is struggling to cope with the heat as he controls traffic at a busy city-centre road junction in Chennai, South India. “I feel like a roasted chicken,” he says. “But it’s actually worse, since I am alive while the chicken would have gone to rest in heaven.”
Excess heat is already claiming many lives. Research published earlier this year in the journal Plos One showed that in May 2010, when the Indian city of Ahmedabad in the state of Gujarat experienced a heat wave with record-breaking maximum temperatures of 46.8C, an estimated 1,344 deaths occurred − 43% higher than expected.
Another chilling statistic in 2012, recently published by the National Crime Records Bureau, is that 5.4% of the total 22,960 road fatalities in India were attributable to heat strokes. That is more than 1,000 people.
The Indian government has done its bit to make the summer slightly more bearable for policemen such as Srinivasan, providing them with packets of aerated fruit juices and buttermilk (yoghurt diluted in water), as well as sunglasses.
“I am just waiting for the summer to be over, or for some of the summer showers that sometimes happen during June,” Srinivasan says before stepping out of the shade of his little booth to start directing traffic manually again in the scorching heat because a power failure has cut out the traffic lights.
Indian politicians, trying to woo voters, put up water pandals (small stalls made of dried palm/coconut leaves) to supply water, and even buttermilk at times, to the public during the recent election period.
In fact, the Indian elections are deliberately timetabled to avoid the worst part of summer, and the entire election process this time was completed by the second week of May, when the sun was beginning to get harsh.
Doctors at the government’s Rajiv Gandhi General Hospital in Chennai have asked the public to take preventive measures to avoid heat strokes – including wearing light-coloured, loose-fitting cotton clothes, staying hydrated, and avoiding strenuous exercise during the day.
And the Regional Meterological Centre (RMC) in Chennai has been publishing weather projections for the state of Tamil Nadu on its website, keeping people informed with with regular updates of projections of average temperatures for one week for every district in the state.
S.R. Ramanan, director of the RMC, told Climate News Network: “The maximum temperature will reach 40˚C in many places in Tamil Nadu in the coming days. It’s going to be sweltering hot.”
While rich and middle-class Indians go for upgraded refrigerators, air conditioners and coolers, the poor households have to settle for earthen pots to keep drinking water cool.
The plight of people is the same, or even worse, in most parts of tropical India during the hostile summers, particularly since fast-moving urbanisation is taking its toll on trees, which are being chopped down to make way for new high-rise buildings, roads and shopping malls
Loss of shade
The loss of the natural shade of avenue trees means that it’s not just humans who are suffering.
The bovine population roams around the streets looking for any tiny puddle of urban gutter water to quench their thirst, and the government’s forest department has had to build concrete tanks and fill them with water to try to prevent animals from suffering dehydration.
Many milkmen live in urban areas and do not take enough care of their cows to protect them from the summer heat, and the Tamil Nadu Veterinary and Animal Sciences University has also found that many aged animals suffer kidney failures in the summer season because of dehydration.
Meanwhile, as more people die every year in India due to heat strokes, social activists are calling for the government to take up initiatives to protect people and spread awareness about preventive measures.
“Curbing privatisation of water and ensuring supply of good quality drinking water for the residents is a major step to avoid dehydration and heat strokes,” said Chennai social activist A.Devaneyan.
“The government health department should conduct awareness campaigns to inform people about taking additional care of elders and children during the summer.”
Devaneyan pointed out that the rising number of players in the bottled drinking water industry has also led to rising prices. He said: “A one-litre bottle now costs 20 rupees. How many can afford that?”
Not surprisingly, the popularity of the Tamil Nadu state chief minister, Ms Jayalalithaa Jayaram, also rose after she recently ordered her government to supply water at 10 rupees per bottle − half the price of the “private” water.
