Long dry spells this monsoon in some parts of India meant warmer days and nights even in July. Climate change is making the world hotter and more humid, and the number of dangerous humid heat days is rising, a new study shows. Sixteen Indian cities saw dangerous humid days for more than six months each year, the study found.
‘Felt temperature’ or ‘wet bulb temperature’ is the thermal discomfort the human body feels and is a combination of maximum temperature and relative humidity. Researchers at Climate Central defined dangerous humid heat days as days when the maximum wet-bulb temperature is 25°C or higher. In simple terms, it could mean a daytime maximum temperature of around 26°C and humidity levels around 20 percent or a variation of the same (use this calculator).
