Impact of Climate Change on Firefighting Extends Beyond Wildfires
Global warming is often mentioned as a factor in the accelerating frequency and intensity of wildfires. However, there are other consequences of global warming that impact the fire service, including new hazards and medical emergencies, emerging training challenges, population migration, and technology developments.
Climate change is often discussed as a future event. However, the impact of wildfires is just the most obvious example of how climate change is already impacting the world, and fire and emergency personnel will be called on to mitigate the effects.
The most obvious and extreme impact of global warming can be seen in the increase of frequency and intensity of wildfires. Hotter and drier weather is extending the wildfire season (maybe to become year-round?). Higher temperatures, low humidity, less rainfall, and high wind increase the likelihood of wildfires.
