Recent survey suggested top 98 out of 100 hottest cities are in India.
El Niño killed 4% of world population 150 years ago .
Our pacific ocean act as Earth’s global thermostat absorbing nearly 90% of global heat to keep the planet’s temperature balanced. But now it is releasing all that trapped energy into the atmosphere.
Normally the wind cycle called 'the Walker circulation’ keeps warm water pushed away from Asia but during Super El Niño effect this cycle completely reverses. So now pacific is sending heat directly towards Indian subcontinent.
The real danger is not 45°C, but the 'Wet bulb theory '.
Wet bulb temperature of 35°C is considered a theoretical limit of human adaptability to heat.
when dry heat is 45°C body evaporates sweat and cool you down. But 35°C wet bulb temperature - high heat + extreme humidity, so air is so saturated that body can’t evaporate sweat.
Many cities in India are reaching this threshold.It impacts weather like weaker monsoon, possible drought.
Did you know about this. How should healthcare stay prepared for such emergency?
