NEW DELHI, Aug 3 – The government said on Wednesday that temperatures during India’s monsoon season had risen this century, and the country could see more frequent heatwaves. Still, it added that heat-related deaths have fallen in recent years.
India suffered its hottest March in more than a century this year, and temperatures were unusually high in April and May, too, mainly blamed on climate change. The government says heatwaves are common, mainly between April and June.
“The average temperature during the monsoon season has been rising in the last two decades,” India’s science and technology and earth sciences minister, Jitendra Singh, told parliament.
“The warming of the tropical Indian Ocean and more frequent El Nino events in the future may lead to more frequent and long-lasting heatwaves over India.”
El Nino is characterized by a warming of sea-surface temperatures in the Pacific. It causes heavy rains and floods in South America and scorching weather in Asia and even east Africa.
Singh said India’s mean temperature during the June-September monsoon season rose to nearly 28.4 degrees Celsius (83.1°F) last year from less than 28 degrees Celsius in 2001.
Heatwave deaths, however, have come down in recent years, according to data provided by Singh to lawmakers that cited newspaper reports.
For this year through July, India recorded 24 such fatalities, none for the whole of last year, and 25 in 2020. That compares with a multi-year high of 505 deaths in 2019.
The minister did not say why there have been fewer fatalities in recent years. Still, a government official told Reuters that most Indian states now have plans ready to alter office and school timings and working hours for laborers to avoid the hottest time of day to reduce exposure. read more.
The World Health Organization says that from 1998-2017, more than 166,000 people died from heatwaves globally. It says that between 2030 and 2050, climate change is expected to cause about 250,000 additional deaths per year from malnutrition, malaria, diarrhea, and heat stress.
