Why are wildfires in Europe so severe this year?
Europe is experiencing its worst wildfire season in two decades, fueled by record-breaking heatwaves and prolonged droughts. Climate change has led to higher temperatures and drier conditions, making forests more vulnerable to fires. Poor land management and neglect of fire prevention measures have also contributed to the severity of these fires.

How is climate change affecting heatwaves and wildfires?
Climate change causes global temperatures to rise, leading to more frequent and intense heatwaves. These extreme heat events dry out vegetation and soil, creating ideal conditions for wildfires to ignite and spread rapidly. The combination of higher temperatures and droughts significantly increases the risk and severity of wildfires worldwide.
-
Which regions are most at risk from these wildfires?
Regions like Southern Europe, including Spain and Portugal, are particularly vulnerable due to their hot, dry climates and history of wildfires. Russia’s wildfire season, while currently less severe, is also at risk as long-term climate trends worsen fire conditions. Other areas affected include parts of the Mediterranean, California, Australia, and parts of Canada.
-
What can be done to prevent or reduce wildfires?
Preventing wildfires involves better land management, including controlled burns and clearing of dry vegetation. Investing in early warning systems and firefighting resources is crucial. Addressing climate change itself by reducing greenhouse gas emissions is essential to tackling the root cause of increasingly severe wildfires and heatwaves.
-
Are wildfires natural or caused by human activity?
While some wildfires can occur naturally due to lightning strikes, many are driven or exacerbated by human activities such as land mismanagement, arson, and neglect of fire prevention measures. Climate change has also increased the frequency and intensity of fires that might otherwise have been less severe.
-
What are the health impacts of these wildfires and heatwaves?
Wildfires release harmful smoke and pollutants into the air, causing respiratory problems and other health issues. Heatwaves can lead to heatstroke, dehydration, and even death, especially among vulnerable populations like the elderly and those with pre-existing health conditions. The combined effects pose serious public health challenges worldwide.
