As global temperatures rise, the incidence of wildfires is becoming increasingly prevalent across many regions.This escalation is primarily attributed to higher average temperatures and changing weather patterns that dry out land and vegetation, rendering them more susceptible to ignitions.

phys.orgA recent study published in Nature Climate Change highlights the growing threat that wildfires pose to biodiversity.The research, led by scientists from the University of Gothenburg, indicates that nearly 84% of species vulnerable to wildfires will face greater risks by the end of this century if current trends continue.

phys.orggu.seThe study combines data from 13 climate models with machine learning to project changes in wildfire dynamics, including the burned area and the length of fire seasons.These predictions are based on various global warming scenarios provided by the Intergovernmental Panel on Climate Change (IPCC).Under a moderate scenario with a projected temperature rise of around 2.7 degrees Celsius, the researchers found that the global area affected by wildfires could increase by approximately 9.3%, while fire seasons may extend by 22.8%.

phys.orggu.seSpecies that are particularly vulnerable include those with limited geographical ranges, which are mainly concentrated in regions such as South America, South Asia, and Australia.A significant proportion of these species are already endangered, and the increased frequency of wildfires could exacerbate their risk of extinction.

phys.orgThe study also underscores important regional differences.While many areas are expected to see an uptick in wildfire risks, certain regions in Africa may experience a decrease in fire-prone areas due to future wetter climates.

gu.seResearch has shown that the ongoing climate change is not only increasing fire frequency but also altering the ecological landscapes that these species inhabit.The conditions conducive to wildfires—such as dead fuel moisture and vegetation dryness—are expected to change, further complicating the survival of many plant and animal species.
