Extreme heat is the most deadly form of weather, killing about 2,000 people a year in the US, and Europe’s heat dome killed more than 1,300 people in less than two weeks this June. According to Mark Wolfe, executive director of the National Energy Assistance Directors Association, the ability to survive rising global temperatures is increasingly determined by economic status, creating a stark divide between those who can afford cooling and those who cannot.
The Growing Economic Barrier to Heat Safety
In wealthy nations like the United States and parts of Europe, the struggle to stay cool is a matter of political and economic priority. While most households possess electricity and cooling systems, millions of families face the recurring choice between paying for electricity and maintaining safe indoor temperatures. Wolfe, who also serves as co-director of the Center on Energy Poverty and Climate, notes that funding for the primary US program that helps families pay their home energy bills is only sufficient to help about one out of six eligible families.

Infrastructure Deficits in the Global South
The challenge in the Global South differs from the Western experience due to a fundamental lack of resources rather than a lack of ideas. Based on observations from recent travel to India, officials there have identified clear strategies—including expanding electricity systems, improving housing, and strengthening public health planning—but remain constrained by limited resources. Shipping air conditioning units to these regions is not a viable solution, as existing electric grids in many developing nations could not support them, even if every family could afford one.
Strategic Investment as a Global Imperative
Addressing energy poverty and heat resilience is not merely a humanitarian obligation; it is also a strategic investment. If the United States and Europe fail to become meaningful partners in financing climate adaptation, other countries will fill that vacuum, expanding both their economic influence and their geopolitical ties across much of the developing world. According to Wolfe, this creates a situation where climate adaptation funding acts as an investment in global health, economic stability and human resilience.
The Shift in Climate Policy
Climate policy has long been measured by how much carbon the world can avoid emitting. However, as global temperatures continue to climb, it may also be judged by whether the world’s wealthiest countries were willing to help billions of people in the global south adapt to a hotter planet. Failure to bridge this gap risks creating a “climate divide,” where survival is dictated by whether those had the resources to adapt or not.
Pro Tip:
Public officials have responded with familiar advice: stay indoors, drink plenty of water and, if possible, turn on the air conditioning.
Frequently Asked Questions
Why is the Global South more vulnerable to extreme heat?
Vulnerability is driven by a combination of unreliable electricity, overcrowded housing, limited access to air conditioning, weak public health systems and widespread poverty.
Is air conditioning the only solution to heat waves?
No. Long-term resilience requires investment in cheaper, more stable forms of clean and secure energy, improving housing, and strengthening public health planning to protect vulnerable populations.
How does energy assistance impact public health?
Low-income energy assistance to help families pay their home energy bills is a core solution in the US to help families keep their home safe during periods of extreme heat.
