It seems like wildfires are becoming more extreme and destructive all around the world. Recent events in countries like Greece, Chile, Canada, and Hawaii have shown the devastating impact of these fires. A new study from the University of Tasmania has confirmed that the number and intensity of the most extreme wildfires have doubled over the past two decades.
Using satellite-based sensors to measure the energy released by fires, researchers identified a total of 30 million fire events over 21 years. They focused on the top 0.01 percent of the most extreme wildfires, which have been increasing in frequency since 2017. These extreme wildfires are not only more frequent but also more intense, releasing twice the energy compared to those at the start of the study period.
The study highlights specific regions like boreal forests in the far north and temperate conifer forests as areas experiencing the most dramatic increase in extreme wildfires. Eastern Siberia, as well as the western US and Canada, are particularly vulnerable to these trends. However, the impact of wildfires depends on various factors, including environmental, social, and economic contexts.
While some regions like the Mediterranean have not seen significant changes in fire activity, the growing number of homes built near fire-prone areas increases human risk. Addressing the root causes behind worsening wildfire activity, such as land cover changes, forest policies, and climate change, is crucial to better prepare for these extreme fires. Traditional firefighting methods may not be enough to combat these increasingly intense wildfires.
In conclusion, the surge of extreme wildfires globally presents a complex challenge that requires immediate attention and action. Understanding the patterns and trends of these fires is essential to developing effective strategies to mitigate their impact. By addressing the underlying causes and implementing proactive measures, we can work towards a more sustainable and resilient future in the face of escalating wildfire threats.
