🔎 Background

Heatwaves have become a growing concern

Heatwaves, an extreme weather condition

• High pressure air settles at 10,000-25,000 ft leading to the creation of warm air domes [1]
• Convection currents are sealed out: staggering warmth and high humidity levels

Alarming consequences on the health of populations [1]

• Dehydration

• Physical and mental exhaustion

• Heat strokes

• In the worst scenarios, death

• Humidity hinders natural heat regulation processes

• Montreal, a victim of climate change

• 58% rise in high humidex nights during 1953-2012 period [3]

• In the last 35 years 500 deaths related to heat waves, most were elderly [3],[4]

• Frequency of lethal heat wave episodes increased to one every year [3]

• Ineffective treatment of issue: increase in usage of Air Conditioning (A/C) adds to the problem

• Particularly vulnerable populations
