Air quality alerts have been issued across Canada and northern USA as smoke from widespread wildfires continues to degrade air conditions, prompting urgent health warnings. Environment Canada has warned residents, especially in Ontario and Toronto (where air quality recently ranked among the worst globally), to limit outdoor exposure. Similar alerts have been issued in US cities like Chicago, where unhealthy ozone levels and residual smoke from Canadian fires are posing additional concerns. Wildfires raging across Manitoba, Saskatchewan, and northern Ontario have forced tens of thousands to evacuate, with emergency responders working to assess the rapidly changing situation. Also, political tensions emerged after some Congress members said Canada’s wildfires were ‘making it difficult for Americans to enjoy their summer’. Scientists attribute the increasing intensity and frequency of wildfires to climate change; Canada is believed to be warming at twice the global rate.

A dense orange haze has enveloped Athens as clouds of Sahara desert dust swept across Greece, marking one of the worst episodes since 2018. Similar clouds hit Greece, Switzerland, and southern France in late March and early April. As the air quality has deteriorated, Greeks with respiratory issues have been advised to stay indoors, wear masks, and avoid strenuous activities. The Sahara annually releases 60 to 200 million tonnes of mineral dust, some of which travels long distances. A meteorologist has compared the view from one weather station to Mars. The fire service has reported 25 wildfires in 24 hours, including one in Crete, where temperatures soared above 30C. The situation underscores the environmental challenges posed by such natural phenomena, requiring vigilant monitoring and response efforts.

New York air pollution is ‘hazardous’, in the Very Unhealthy category, with no end in sight for the thick smoke pouring south from more than 400 Canadian wildfires. At least 13 US states have air quality alerts issued, impacting approximately 115 million people. Experts said the pollution could persist into the weekend. There have been mass evacuations in Quebec province. Canadian officials warned that this could be the country’s worst wildfire season on record, with over 6.7 million acres already scorched. By 8 June hundreds of uncontrolled forest fires were threatening Canada’s critical infrastructure and forcing evacuations. Wildfires are common in Canada’s western provinces, but this year they rapidly spread east. About 9.4m acres have already burned. Canada’s wildfires are part of our new climate reality.

As of 17 May, 88 wildfires were still burning across Alberta, and dozens more across British Columbia and Saskatchewan. Weeks of uncontrolled blazes have made air quality dangerously poor, changing the bluebird sky to an eerie orange glow. Environment and Climate Change Canada issued a special air quality statement as ‘very high risk’. Air quality is so poor that even those without pre-existing health conditions could have difficulty breathing, especially if doing strenuous activity outside. An Environment Canada meteorologist said, ‘It is potentially a really dangerous situation that everyone must take seriously’. Pray for children, older adults, and those with lung or heart conditions to be sensible and cautious and stay inside if breathing becomes difficult. Pray for healthy people to be aware of tell-tale symptoms such as sore throat, coughing, or being very tired or lethargic. Not feeling very good can even be attributed to air quality.
