The Spread of Smoke from Intense Forest Fires
The intense forest fires in the Amazon and other regions are causing smoke to spread throughout Brazil and beyond. Nearly five million km2 have been affected by the smoke in Brazil, approximately 60% of the country’s territory.
Impact on Air Quality and Health
The smoke has created air quality issues, with regions in Argentina and Uruguay also reporting its presence. Cities like Sao Paulo and Rio de Janeiro in Brazil are experiencing elevated levels of fine particles, leading to respiratory problems for residents. The pollution levels have far surpassed the recommended limits set by the World Health Organization.

Causes and Environmental Effects
The fires, largely attributed to criminal activity and agricultural practices, are exacerbated by historic droughts linked to climate change. Images from NOAA satellites show a thick gray smoke cloud drifting southward over the Andes, affecting various regions. The smoke carries soot nanoparticles, worsening air quality in already dry areas.
Current Situation and Future Outlook
The number of wildfires in the Amazon has nearly doubled compared to last year. Other parts of Brazil, such as the Chapada dos Veadeiros National Park, are facing devastating wildfires. The smoke has even impacted the color of sunsets in many regions, casting an orange-red hue due to the presence of invisible nanoparticles. With no immediate relief in sight, regular precipitation is needed to alleviate the effects of the smoke, but such rainfall is not expected until October or November.
