New Delhi is experiencing severe air pollution, causing the city’s iconic Red Fort to show signs of damage and sparking protests from concerned residents. Despite decades of air pollution plans, the air quality remains dangerously unhealthy, particularly during the winter months. The government’s recent cloud seeding experiment, aimed at washing away the toxic air, was unsuccessful, and scientists point out that the needed conditions to do so are generally absent during Delhi’s winter. Residents and experts are urging the government to address the pollution at its source, as the current situation significantly impacts public health and causes millions of pollution-related deaths annually.

A new study published in Nature estimates that wildfire smoke causes over 41,400 excess deaths annually in the U.S., a figure more than double previous estimates. The research projects a significant increase in these deaths, up to an additional 26,500-30,000 by midcentury due to climate change. Wildfire smoke is now considered a greater health risk than other climate change-driven threats, such as extreme heat. The study’s findings could influence public policy, particularly regarding environmental regulations.

Canada’s 2025 fire season is shaping up to be the second-worst on record, with over 470 out-of-control fires burning across the country, impacting tens of thousands of people. A staggering 7,318,421 hectares have already burned, significantly exceeding the five-year average, a stark reminder of the impacts of climate change. Warmer temperatures are extending the fire season and exacerbating conditions, causing more intense blazes that are difficult to control, with the prairie provinces being the most affected, followed by fires now hitting the east coast. This is the third year in a row that Canada has experienced far above-average fire activity, causing widespread evacuations, air quality issues, and impacting populations internationally.

As the Lee fire in Colorado continues to grow, officials evacuated the Rifle Correctional Center, relocating 179 incarcerated individuals due to the rapidly expanding blaze. The fire, now the sixth-largest in Colorado’s history, has consumed over 167 square miles and prompted evacuation orders for mountain communities. Firefighters are working to contain the fire amidst concerns regarding air quality due to smoke from the Lee and Elk fires. Simultaneously, California is battling several wildfires, including the Canyon fire, which is 62% contained, and the Gifford fire, which has burned at least 180 square miles.

Hanoi’s air quality reached critically hazardous levels on Friday, registering 266 micrograms of PM2.5 per cubic meter, the highest globally according to AirVisual. This severe smog, attributed to traffic, industrial activity, and waste burning, has prompted the government to accelerate its transition to electric vehicles by 2030, aiming for at least 50% of buses and 100% of taxis to be electric. Experts cite unfavorable weather conditions, trapping pollutants, as a contributing factor, with improvement not expected until the arrival of rain in March. The ongoing pollution affects residents of all ages, causing respiratory problems and reduced visibility.

Delhi is currently experiencing a severe air pollution crisis, with levels reaching 30-35 times the WHO safe limit. This annual winter phenomenon, caused by factors such as crop burning, vehicular emissions, and low wind speed, has reached alarming levels this year, with AQI readings hitting 500 in several areas, including Delhi, Noida, and Gurgaon. The smog is so thick that it is visible from space, impacting flight operations and causing widespread health issues, with over 81% of families reporting at least one member suffering from pollution-related ailments. Despite the Delhi government’s efforts to combat pollution, including the implementation of the Graded Response Action Plan, the situation remains critical, highlighting the urgent need for stricter environmental regulations and a comprehensive approach to tackling this growing public health concern.
