Rising global temperatures have increased the frequency and intensity of wildfires worldwide, especially in northern and temperate forests. These extreme fires have sparked significant legal claims affecting agriculture, forestry, tourism, and infrastructure. Accurately understanding wildfire smoke dispersion is vital in legal disputes to identify which fires caused specific impacts and to gauge their effects amid multiple simultaneous wildfires.
In recent decades, wildfire size and intensity worldwide have increased significantly alongside rising global temperatures. Scientific studies using satellite data over the past 20 years show that extreme wildfires have more than doubled in frequency and intensity globally, particularly in northern and temperate forests such as western North America, boreal forests of northern North America and Russia, and parts of Australia. These wildfires have driven significant legal actions as affected parties seek compensation for damages. The economic impact spans sectors including agriculture, forestry, tourism, and infrastructure, compounding financial pressures on communities and insurers and fueling litigation over liability and compensation. This trend is expected to persist or worsen in coming years.
