New York Issues Air Quality Alert as Canadian Wildfire Smoke Spreads

Smoke from ongoing wildfires in Canada has prompted New York state officials to issue an air quality health advisory for Saturday, affecting Long Island, the New York City Metro area, the Lower and Upper Hudson Valley, and the Adirondacks. The Department of Environmental Conservation and Department of Health warned that air quality is considered "unhealthy for sensitive groups" in these regions, with the air quality index (AQI) expected to exceed 100 and potentially reach 135.

The AQI is used to measure air pollution levels and associated health risks, with higher numbers indicating greater danger. Similar alerts have been issued in other parts of the United States, including Chicago and areas of New England, as smoke continues to drift south from Canada.

Canadian authorities report that more than 550 wildfires are currently active, particularly in Manitoba, and over 6.1 million hectares of land have burned in the past year. Recent months saw large-scale evacuations in Saskatchewan and Manitoba, where states of emergency were declared. Scientists attribute the increasing frequency and intensity of wildfires to climate change, noting that Canada is warming at about twice the global average rate.

The impact of the smoke has also drawn attention from U.S. lawmakers. Earlier in July, six members of Congress wrote to the Canadian ambassador, expressing concern about the effect of wildfire smoke on Americans' ability to enjoy the summer.
