In the summer of 2023, Quebec, Canada witnessed an alarming surge in extreme fires, which were found to be twice as likely and more intense due to human-caused global heating, according to researchers. The World Weather Attribution (WWA), a climate change research initiative, recently released a report highlighting the connection between climate change and the unprecedented fires.
As the fires raged on, spreading from east to west coast, their scale reached a staggering 14 million hectares (34.6 million acres) – an area larger than Greece. This magnitude prompted the WWA to investigate the role of climate change in amplifying the 2023 Canadian wildfires. Focusing on Quebec, the report revealed that climate change, primarily driven by fossil fuel consumption, exacerbated dry and “fire-prone” conditions by up to 20-50% more intensity than average.

The report attributed the extreme conditions to factors like reduced precipitation and elevated temperatures. The Fire Weather Index (FWI), which measures wildfire risk based on meteorological factors, reached a record high in 2023. This heightened FWI contributed to drier, more flammable forests and vegetation, creating a perfect environment for fires ignited by both lightning and other sources.
The significant scope of the fires across Canada left experts astonished. Fires ignited in the east of the country in June persisted in the west and northern regions until late August. This extended duration highlighted the dire impact of climate change on wildfire patterns. Furthermore, the 2023 wildfires produced record carbon emissions, exacerbating the challenge of global heating.
It’s crucial to address the underlying cause of these devastating wildfires by reducing emissions in line with international climate targets. The failure to do so will only lead to an escalation in the intensity and frequency of such events. Experts emphasise that until fossil fuel consumption is curtailed, the threat of more frequent and extensive wildfires will persist.
This research provides a unique perspective on the relationship between climate change and wildfires, offering insights that can aid communities in adapting and building resilience against the growing threat. By understanding the risks posed by global heating, these findings can contribute to mitigating the impact of emergencies and disasters on a global scale. As the world braces itself for more frequent wildfires, adapting and taking proactive measures becomes paramount.
