A United Nations weather agency has issued a formal warning that wildfires and heat waves are now measurably degrading air quality across the globe, with direct consequences for human health and climate stability. The threat is not confined to fire-prone regions — smoke crosses borders, heat traps pollutants, and the cycle compounds itself with each passing season. The agency's call for coordinated international response reflects a recognition that these are not separate crises but interlocking forces reshaping the conditions under which billions of people breathe and live.
