Canada wildfires create space‑visible smoke, worsening US air quality

More than 850 forest fires are currently burning across Canada, with the largest plume concentrated over Manitoba, Saskatchewan and Ontario. Satellite imagery from NOAA‑21 shows the smoke column extending from southeast Canada into the northeastern United States, making the haze visible from orbit.

The dense smoke has driven air‑quality alerts across the border. New York recorded a "very unhealthy" rating, and other U.S. regions reported hazardous conditions. British Columbia authorities issued a warning about air‑pollution from fires in the north‑west United States, noting the cross‑border impact. According to media reports, U.S. President Donald Trump has accused Canada of inadequate fire‑management, heightening diplomatic tension as both nations grapple with the health consequences of the smoke.
