New York City is currently facing its worst air quality since the 1960s due to the smoke from wildfires burning in Canada. The Financial Times reports that the air quality in New York was ranked the worst in the world on Thursday. The smoke has caused air quality alerts in the Northeast and has even grounded airplanes.

According to CBS New York, officials have advised residents to stay indoors and to avoid any strenuous outdoor activities. The smoky skies have also caused visibility issues and reduced air quality levels throughout the region.

The New York Times provided an opinion piece on the matter, stating that the future becomes clear as the smoke darkens the sky. The article warns about the impact of climate change and the need to take action to prevent more severe consequences.

The smoke from the wildfires in Canada has triggered hazardous air quality alerts across the U.S. and is causing widespread disruptions to transportation. Yahoo News reports that several U.S. airlines have had to cancel flights due to poor visibility caused by the smoke.

As the situation continues to develop, officials are urging people to take precautions to protect their health and to stay informed about any updates or alerts.
