Climate Change: A Big Problem

The escalating frequency, intensity and severity of wildfires is being driven by extended periods of heat, drought, and high winds.

The year 2023 served as a stark reminder of the escalating threat of wildfires, driven by climate change. Globally, over 400 million hectares (988 million acres) were reduced to ashes, resulting in the deadliest year for forest fires in the 21st century. The toll was catastrophic: over 250 lives lost and an alarming release of 6.5 billion tonnes of carbon dioxide into the atmosphere.

In late June 2021 a heatwave of unprecedented magnitude impacted the Pacific Northwest region of Canada and the United States. Many locations broke all-time maximum temperature records by more than 5 °C, and the Canadian national temperature record was broken by 4.6 °C, with a new record temperature of 49.6 °C

Scientists warn that we are entering an era of extreme weather conditions driven by climate change. Alarmingly, approximately 75% of California's 20 most destructive wildfires—measured by structures burned—have occurred since 2015. It's evident that traditional firefighting strategies are struggling to keep pace. Fire trucks, hydrants, and aerial support are no longer adequate to combat the rapid spread of modern wildfires.

The recent firestorms, with their unprecedented velocity and ferocity, exposed the inadequacy of existing firefighting techniques and equipment. The inadequate regional infrastructure reflects a social perception that extreme warmth is not a substantial threat in North America.

We are seeing a persistent vulnerability to warm temperature extremes.

Current Firefighting Methods Can’t Keep Up

Should these extreme weather patterns persist, or even accelerate as predicted, we must anticipate that devastating fires will become a recurring, and escalating, environmental challenge.

The abnormally hot conditions in 2024 alone, compared to average temperatures from 1980 to 2023, account for 25% of the moisture deficit that contributed to the wildfires. This deficit is largely due to substantial anthropogenic warming.

While the Sun Belt region serves as a stark example of this phenomenon, the increased frequency and severity of natural disasters have triggered unprecedented levels of loss of life and property damage nationwide. Consequently, insurance markets, now acutely aware of climate risk, are fundamentally altering the economics of homeownership. They are either significantly increasing premiums or withdrawing coverage entirely from high-risk communities across the country.
