220 crore people in India, Pakistan to face deadly heat if global temperature rises by 2 deg C: Research
New Delhi, Oct 10 (PTI) If global temperatures rise by 2 degrees Celsius above pre-industrial levels, around 2.2 billion (220 crore) people living in the Indus River Valley in northern India and eastern Pakistan may experience extended periods of heat that exceed human tolerance, according to a new research.
The research, published in the peer-reviewed journal Proceedings of the National Academy of Sciences (PNAS), indicates that in such a scenario, northern India, eastern Pakistan, eastern China and Sub-Saharan Africa would predominantly encounter high-humidity heatwaves.
Heatwaves with higher humidity levels can be more perilous because the air cannot efficiently absorb excess moisture. This limitation restricts the human body’s ability to evaporate sweat and affects the moisture content of certain infrastructure like evaporative coolers.
