• More than 900 active wildfires are burning in Canada, prompting President Trump to threaten new tariffs on Canada for alleged negligence in forest management, while Canadian officials emphasize shared responsibility in combating climate change.
• Health experts warn that toxic smoke particles pose significant risks, especially to vulnerable populations, and recommend using air purifiers and N-95 masks to reduce exposure to harmful pollutants.
• Firefighters in Minnesota are battling volatile wildfires that have burned over 70,000 acres and forced evacuations, while the region experiences record-breaking poor air quality amid forecasts of thunderstorms, flooding, and possible tornadoes.
