Zombie Fire Season Is Here in the Arctic
The Arctic region has long been known for its stunning landscapes and unique wildlife. However, in recent years, it has also gained attention for a rather sinister phenomenon - zombie fires. These fires, which can smolder beneath the snow and ice for several months, have become an alarming new reality in the Arctic.
What exactly are zombie fires? They are not fires caused by the reanimation of the undead, but rather wildfires that never truly die out. During the warmer months, wildfires can ignite in the Arctic due to lightning strikes or human activities. But the peculiar nature of the region’s peatlands and forests, combined with the changing climate, makes them prone to smolder even when covered by snow.
Peatlands, which are saturated wetlands found in the Arctic, store vast amounts of organic matter. When a fire occurs, the flames can consume the vegetation on the surface, but the underlying peat continues to burn slowly and release greenhouse gases, mainly carbon dioxide and methane. When the winter arrives and snow covers the fire, the lack of oxygen prevents the flames from igniting openly. However, the peat continues to burn silently, later reviving as temperatures rise in the following year.
This process, known as overwintering, is what makes these wildfires “zombie fires.” They can reignite, spreading flames once again during the next fire season. This poses a threat to both human settlements and the fragile Arctic ecosystems. The increase in wildfires and their prolonged duration also means higher greenhouse gas emissions, exacerbating the issue of climate change.
Over the past decade, the Arctic has witnessed a significant increase in wildfire activity. The extreme heatwaves, longer dry spells, and reduced snowfall caused by climate change create ideal conditions for these fires. In 2020 alone, the Arctic experienced unprecedented fire activity, with nearly 600 anomalous wildfires burning across Siberia and the Arctic Circle. These fires emitted a staggering amount of carbon dioxide, equivalent to the annual emissions of some countries.
Apart from the environmental impact, zombie fires also have socioeconomic implications for the local communities. The smoke from these wildfires can decrease air quality, leading to respiratory issues for humans and wildlife. The fires can also encroach upon inhabited areas, destroying infrastructure and disrupting the lives of indigenous peoples who rely on the land for their livelihoods.
To mitigate the risks posed by zombie fires, many scientists, policymakers, and local communities are working on various approaches. Early detection systems using satellites and drones have been deployed to locate and monitor these hidden fires. Firefighters are also being trained to combat these fires in winter conditions, which poses unique challenges due to the frozen landscape.
Tackling climate change is crucial to halt the intensification of these wildfires. Reducing greenhouse gas emissions, protecting and restoring peatlands, and promoting sustainable land management practices are some of the key measures that need to be taken. Collaborative efforts on an international level are necessary to address the impacts of climate change and ensure the protection of the Arctic.
Zombie fires in the Arctic are a chilling reminder of the climate crisis we are facing. As temperatures continue to rise and extreme weather events become more frequent, the fight against these fires becomes even more critical. We must act swiftly and decisively to protect not only the fragile ecosystems of the Arctic but also the future of our planet.
