More than 600 million people are facing severe cooling poverty, according to a study reported this week [1].
The findings highlight a growing humanitarian crisis where the inability to access cooling is not merely a lack of technology, but a result of systemic failure. As global temperatures rise, the lack of thermal safety increases the risk of heat-related illness and death for the world's most vulnerable populations.
The analysis focuses heavily on the Global South and other heat-vulnerable regions worldwide [3]. Researchers said that systemic cooling poverty occurs when intersecting forms of systemic deprivation prevent individuals from attaining thermal safety [3], [4]. This means that factors such as poverty, poor housing quality, and lack of infrastructure combine to make cooling inaccessible.
Cooling poverty is distinct from a simple lack of air conditioning. It represents a broader failure of systems to protect people from extreme heat, a challenge that disproportionately affects those in lower-income brackets who cannot afford electricity or efficient cooling solutions [4].
Because these fault lines are often overlooked, the study suggests that temperature alone does not determine heat vulnerability [3]. Instead, the intersection of economic status and environmental exposure creates a dangerous gap in safety for more than 600 million people [1].
“More than 600 million people are facing severe cooling poverty.”
This study shifts the conversation on heat vulnerability from a meteorological issue to a socio-economic one. By defining 'cooling poverty' as a systemic deprivation, it suggests that providing air conditioners is an insufficient solution. Addressing the crisis will require structural interventions in housing and energy infrastructure, particularly across the Global South, to ensure that thermal safety is a basic right rather than a luxury of wealth.
