A portion of Kathmandu, Nepal, is covered by a thin layer of smog that shrouds the atmosphere of the bowl-shaped Kathmandu Valley on October 17, 2025, with the Air Quality Index measuring above 100. The average readings of Kathmandu's pollution exceed the annual average concentrations of PM2.5 of 5 ug/m3, while 24-hour average exposures should not exceed 15 ug/m3 more than 3-4 days per year, as prescribed by the World Health Organization. PM2.5 refers to particulate matter (solid or liquid droplets) in the air less than 2.5 micrometres in diameter. It is among the most dangerous pollutants that can get past the nose and throat to penetrate the lungs and even the bloodstream. PM2.5 particles are small and are also likely to stay suspended in the air for long, increasing the chances of people inhaling them. According to Nepal's Environmental Protection Agency's air quality index, an air quality reading of 151-200 is considered unhealthy, causing everyone to experience problems and sensitive groups to feel more severe effects. When air quality reaches 201-300, it is considered a very unhealthy level, and health risks increase for everyone in the area. When it crosses 300, it becomes hazardous, meaning that the air is of extremely poor quality and poses serious health risks to everyone.

A woman holds a thin layer of ice that covers an oak leaf during an ice storm caused by freezing rain in Toronto, Ontario, Canada, on March 30, 2025. Environment Canada issues a 'freezing rain warning' for Toronto early Sunday as the city expects to see ice build-up between three to five millimeters. Over 220,000 customers are without power in Ontario due to the ice storm. Hydro One, the provincial power utility, indicates that the outages are concentrated in central Ontario, from Tobermory and Gravenhurst to Peterborough and Kawartha Lakes.
