Heat, humidity during India's monsoon may extend summer heat stress: Study

Hot and humid conditions prevailing during India's monsoon season could extend the duration of uncompensable heat stress of the summer season under a global warming of 2 degrees Celsius, a study has found. Findings published in the journal American Geophysical Union (AGU) Advances highlight a "surge of UHS (uncompensable heat stress) during the monsoon season (July-October) as the climate warms". Researchers from the Indian Institute of Technology (IIT) Gandhinagar and the US' Stanford and Purdue universities said long-lasting uncompensable heat stress across both the seasons -- summer and monsoon -- could pose critical challenges to public health, labour productivity, and climate resilience in densely populated and vulnerable regions. Uncompensable heat stress occurs when one's body is unable to cool down through sweating or other mechanisms due to extreme heat and humidity. A sustained accumulation of heat can endanger human health, including causing heat-related illness, organ .

Over 75% of Delhi remained heat-stressed for six years or more: Report

About 75.78 per cent of Delhi's area remained heat-stressed for six or more years between 2015 and 2024, with a majority of construction sites, marketplaces and schools located in areas experiencing recurring extreme heat, according to a report by the Centre for Science and Environment (CSE). The report, titled "Making Delhi Heat-Resilient: A Roadmap with the Focus on Vulnerable Groups", said that 98.72 per cent of Delhi's total area crossed the heat-stress threshold at least once during the decade. According to the study, 92 per cent of construction projects are located in areas where land surface temperatures crossed the 45 degrees Celsius threshold at least once between 2015 and 2024, while 77 per cent are in areas witnessing recurring extreme heat. About 84 per cent of the 643 mapped marketplaces, including major mandis, are situated in areas experiencing recurrent heat stress, while 76 per cent of mapped informal settlements housing nearly 1.32 million people are located in ...

Exceptionally early heat wave shatters records, causes deaths across Europe

The United Kingdom smashed a century-old temperature record for the second time in 24 hours on Tuesday as a spring heat wave scorches parts of Western Europe, triggering government warnings about risks to life. Several drownings were reported in Britain and France as people tried to cool down. A temperature of 35.1 degrees Celsius (95.2 degrees Fahrenheit) was recorded at London's Kew Gardens, Britain's Met Office weather service said, breaking the 34.8 C (94.6 F) record set a day earlier at Kew. The provisional readings smashed the long-standing record of 32.8 C (91.4 F) set in 1922 and matched in 1944. London also recorded a rare "tropical night", defined as one in which the temperature does not fall below 20 C (68 F). Records also fell in France, where temperatures reached 36 C (97 F) on Monday in the country's southwest and widely remained above 20 C at night. The national weather service, Meteo-France, said a "heat dome", with heat held in place by a high-pressure weather fron
