Understanding the heat better
Hindustan TimesThe deepening effects of the climate crisis are throwing traditional models of climate prediction awry and underlining the need for more sensitive mitigation and adaptation plans. The India Meteorological Department took a step forward in responding to this trend this week, announcing plans to issue heat index readings for weather stations by calculating “real feel” heat index. Measures of heat index and wet-bulb temperature — which were published in HT every day last summer — provide a more nuanced understanding of the impact of heat than what bald readings of temperatures can manage. The World Bank estimated last year India could account for 34 million of the 80 million jobs lost globally due to heat stress. Since the heat index remains high as long as relative humidity is high, mitigation plans will need to be extended to August and look beyond the months of dry heat, which is often deemed by experts as less dangerous because the body can still cool down by sweating.
