Delhi has officially surpassed Lahore to become the world’s most polluted major city as a thick, suffocating blanket of smog descended upon the Indian capital this Friday. With a population of 20 million, the city faced hazardous conditions, as reflected by the Swiss group IQAir, which recorded an Air Quality Index (AQI) of 334. Meanwhile, India’s own Central Pollution Control Board reported even more alarming figures, tagging the air quality at a "severe" 403. While the exact metrics differ between organizations due to varying calculation methodologies, the visual reality on the streets was undeniable, with heavy smog obscuring traffic and streetlights across the metropolis.

This annual crisis is a recurring struggle for Northern India and neighboring Pakistan, where winter weather patterns exacerbate the situation. As temperatures drop, the cold, stagnant air traps pollutants from various sources, including heavy vehicle emissions, persistent construction dust, and the seasonal burning of agricultural waste. The result is a dangerous cycle that turns the region’s atmosphere into a health hazard for millions, underscoring the severe environmental challenges faced by the capital as it struggles to clear its air.
