New Delhi: Summer heat is intensifying all over the country. There are reports that there is a possibility of heat wave and sunstroke. The Meteorological Department has issued a heat wave warning in nine states. Three states of West Bengal, Bihar and Andhra Pradesh will experience dangerously high temperatures. Orange alerts have been issued in these places.

Doctors have been advising people to carry water while travelling and not stepping out without an umbrella.

Last day, 13 people who participated in Union Home Minister Amit Shah's public program in Navi Mumbai died due to sunstroke and dehydration. It was also reported that about 150 people were confused. 12 people died due to sunstroke while attending the Maharashtra Bhushan award ceremony at Kharghar Corporate Park in Mumbai. 24 people are undergoing treatment in different hospitals.

According to the study conducted by Ramit Debnath and colleagues at the University of Cambridge, Delhi is particularly vulnerable to severe heatwave impacts.

Already Heavy damage was reported in the Indian subcontinent following last year's heat wave. After this, there was a big setback in global wheat exports. In the current situation, the threat of load shedding is also present in many places.

India has already done quite a bit in terms of heat mitigation - they actually now recognize heatwaves as part of their disaster relief package, but there's a need to optimise the pace of these plans. Debnath commented.

The researchers also warned that heatwaves were weakening India's efforts to meet its "Social Development Goals", a list of 17 U.N. objectives to cut poverty, hunger, inequality, and disease.

Extreme heat could ultimately lead to a 15% decline in "outdoor working capacity", reduce the quality of life of up to 480 million people and cost 2.8% of GDP by 2050, they said.

Falling productivity caused by extreme high temperatures could already be costing India 5.4% of its GDP, according to the Climate Transparency Report published by environmental groups last year
