Delhi's Air Pollution Reaches 'Severe' Levels Amidst Winter Smog

Air pollution in Delhi has reached 'severe' levels as temperatures and wind speeds dropped, causing reduced visibility and affecting flights. The capital has topped global pollution charts and is combating toxic smog from cold air trapping pollutants. Measures include closing schools and limiting vehicle usage.

Delhi has been engulfed in a severe layer of air pollution, marking the first 'severe' level of the season on an official index. The drop in temperature and wind speed has severely deteriorated visibility, impacting air traffic, with at least eight flights being diverted from the Indira Gandhi International Airport.

Recently overtaking Lahore, Delhi is now the world's most polluted city according to Swiss group IQAir's live rankings. The situation poses serious health risks, as the 24-hour air quality index (AQI) soared to distressing levels, reaching a score of 418. Exposure at this level can impact healthy individuals and exacerbate conditions in those with preexisting health issues.

To combat these hazardous conditions, authorities have intermittently resorted to measures such as closing schools, halting some construction activities, and restricting the use of private vehicles. Meanwhile, in Pakistan's Punjab province, similar actions have been taken to combat toxic air as schools remain closed and outdoor activities are restricted.
