New york: A comprehensive global study has highlighted a concerning trend of increasing nighttime temperatures in 83% of the world's major cities. The study reveals that these temperatures are rising up to ten times faster than daytime averages during periods of extreme heat.

According to BERNAMA News Agency, the analysis conducted by Climate Resilience for All titled "Extreme Heat and the Shrinking Diurnal Range: A Global Evaluation of Oppressive Air Mass Character and Frequency" examined weather data from 1994 to 2024. The study focused on 'dry tropical' and 'moist tropical' air masses, both of which pose significant risks to human health due to their hot and dry or hot and humid characteristics. Researchers identified these conditions as increasingly common and dangerous in urban areas globally.
