Wildfire smoke is becoming an increasingly dangerous global health threat as climate change fuels more frequent and intense forest fires, with environmental advocates urging governments to adopt stronger climate policies, support Indigenous-led forest management and accelerate the transition away from fossil fuels.
The warning comes as widespread wildfires continue to affect forests across several regions of the world, sending smoke across international borders and exposing millions of people to hazardous air pollution that poses serious risks to human health and ecosystems.
Recent wildfire events have demonstrated that smoke generated in one country can travel thousands of kilometres, affecting air quality far beyond the areas where the fires originate.
Smoke from Canada’s devastating wildfire seasons has crossed the Atlantic Ocean in recent years, triggering air quality alerts in parts of Europe and reinforcing concerns that climate change is creating increasingly interconnected environmental and public health challenges.
Scientists and environmental experts say wildfire smoke should no longer be viewed as a temporary seasonal nuisance because it contains fine particulate matter, toxic chemicals, heavy metals and black carbon capable of penetrating deep into the lungs and bloodstream.
Research has shown that exposure to wildfire smoke can increase the risk of respiratory illnesses, cardiovascular diseases, strokes and other long-term health complications that may persist even after smoke has cleared from the atmosphere.
The United Nations Environment Programme has also warned that extreme wildfire events could increase by as much as 50 percent globally before the end of the century if greenhouse gas emissions continue on their current trajectory.
Communities living near wildfire zones often face the greatest burden, with thousands of residents forced to evacuate their homes while forests, biodiversity and livelihoods are destroyed by advancing flames.
Indigenous communities are among those disproportionately affected, as many depend directly on forests for their cultural heritage, livelihoods and traditional ways of life.
Environmental campaigners argue that governments have not matched their climate commitments with sufficient action.
While authorities frequently issue air quality advisories and announce emissions reduction targets, many countries continue to provide financial support for fossil fuel development and industrial activities that contribute to global warming.
Critics contend that continued investment in fossil fuels undermines efforts to address the root causes of increasingly destructive wildfire seasons.
Experts are also calling for major reforms in forest management practices.
They note that decades of suppressing natural fires, widespread clear-cut logging and the establishment of monoculture plantations have reduced forest resilience and increased the accumulation of combustible vegetation, making forests more vulnerable during prolonged heatwaves and droughts.
Greater emphasis is now being placed on ecological restoration and sustainable forest management that promotes biodiversity rather than uniform tree plantations.
Environmental specialists also highlight the importance of protecting primary and old-growth forests, which store significant amounts of carbon, maintain soil moisture and help reduce the impacts of climate change.
Preserving these forests is considered one of the most effective and cost-efficient natural climate solutions available.
Another key recommendation is the restoration of Indigenous fire stewardship.
For generations, Indigenous Peoples have used carefully planned, low-intensity cultural burning to reduce excessive vegetation, improve ecosystem health and lower the risk of catastrophic wildfires.
Researchers increasingly recognise that incorporating Indigenous knowledge into modern forest management can strengthen climate resilience while protecting biodiversity.
Campaigners further advocate redirecting public funding away from fossil fuel subsidies towards renewable energy, forest restoration and community resilience programmes.
They also support stronger measures requiring major polluters to contribute financially to addressing climate-related damages.
Environmental organisations maintain that governments must honour their commitments under the Paris Agreement and intensify efforts to reduce carbon dioxide and methane emissions.
They argue that limiting global temperature rise remains essential to reducing the frequency and severity of extreme wildfires while safeguarding public health, protecting forests and ensuring a more sustainable future for communities around the world.
