And while most of the wildfires in the data are small over 85% burned fewer than 10 acres they still account for more than 140 million acres burned collectively. Florida, for instance, has seen several of its largest fires over the past two decades in May . Lightning is the most common ignition source that causes the vast majority of wildfires. A Warner Bros. The fires have left a trail of destruction in their wake. The historic practice of putting out all fires also has caused an unnatural buildup of shrubs and debris, which can fuel larger and more intense blazes. One of the most common causes of wildfires is burning debris. The full report is impressive. However, every action to mitigate climate change and slow down global warming can effectively reduce the risk of extreme weather events such as lightning strikes and thus decrease the chances of wildlife fires. Unlike many natural disasters, most wildfires can be prevented. Over the 21-year study period, the major causes were debris burning and arson, while campfires and fireworks were responsible for only 5% of fires.

The most dangerous part of a blaze is called the head fire, explains Thomas Smith. A 2014 study estimates a 12% increase in the frequency of lightning strikes with every one degree Celsius increase in temperature. The principal natural cause of wildland ignitions is lightninga major feature of the season in 2020. Wildfires are ruinous so how to stop them happening in the first place? Furthermore, steady temperatures and rainfall can drastically reduce the amount of dry vegetation. In January 2022, the Biden administration announced a multibillion-dollar plan to make forests more resilient and reduce the risk of wildfires on up to 20 million hectares of land near vulnerable communities.
