Pollution Is Not Protection: Clean Air and Heat Resilience Must Go Together

A recent statement suggesting that pollution particles may reduce the impact of heat by blocking some sunlight has sparked a wider debate on climate, public health and urban living. The argument claims that in India, even when temperatures rise to around 45°C, pollution particles in the air may reduce the amount of sunlight reaching the ground. In contrast, parts of Europe with cleaner air may experience temperatures of 35°C to 40°C as extremely harsh.

While there is a scientific basis for saying that certain aerosol particles can scatter or reflect solar radiation, this argument needs serious correction. Pollution must never be presented as a benefit or a form of protection.

The Intergovernmental Panel on Climate Change notes that sulphate aerosols can influence climate forcing by scattering solar radiation and affecting clouds, but it also highlights their impact on air quality and ecosystems. In simple terms, some particles may reduce sunlight at ground level under certain conditions, but that does not make polluted air safe, desirable or acceptable.

Air pollution is a major public health threat. Fine particulate matter can enter deep into the lungs and is linked to respiratory illness, aggravated asthma, reduced lung function, heart disease and other serious health risks. Children, elderly people and people with existing heart or lung conditions are among the most vulnerable groups.

This is why poisonous air cannot be called protection. A city where people struggle to breathe cannot be described as safer simply because some pollution particles reduce sunlight. Such thinking risks normalising toxic air and weakening the urgency of pollution control.

Europe’s experience of severe heat is also shaped by many factors beyond air cleanliness. Humidity, long summer days, heat-trapping urban design, concrete-heavy cities, limited green cover, and buildings not designed for high temperatures can all increase heat stress. Recent reporting on European heatwaves has highlighted the role of urban heat islands, where surfaces such as asphalt and concrete absorb and radiate extreme heat, making cities more dangerous during hot weather.

This shows that the real challenge is not choosing between clean air and heat protection. The real challenge is building cities that can handle rising temperatures without harming public health. Clean air and climate resilience must move together.

Governments, urban planners and citizens need to focus on practical solutions such as stronger pollution control, clean energy adoption, better public transport, increased tree cover, shaded public spaces, cool roofs, climate-resilient buildings, heat-health action plans and public awareness campaigns. The World Health Organization says the health impacts of extreme heat are largely preventable through public health preparedness and risk management.

India, Europe and other regions facing rising heat must treat both heatwaves and air pollution as serious public health challenges. One danger cannot be used to justify another. Heat is dangerous. Pollution is dangerous. Public health should never be compromised in the name of convenience.

The message is clear: polluted air is not a shield. Clean air, climate-resilient cities and responsible environmental planning are the real protections society needs.
