According to the Fourth National Climate Assessment Update 2018, which region will face an increased threat from wildland fires?

The Southwest region is identified in the Fourth National Climate Assessment Update 2018 as facing an increased threat from wildland fires due to various interrelated factors. This area experiences a generally drier climate, which contributes to a higher likelihood of wildfires when combined with rising temperatures and prolonged drought conditions. Additionally, the fuel load, including vegetation and underbrush, tends to be more prevalent in the Southwest, creating favorable conditions for fires to ignite and spread rapidly.

Predicted climate changes, such as increased aridity and extreme weather events, exacerbate these risks, making it crucial for fire prevention and management strategies to adapt to the expected patterns of wildland fires in this region. In contrast, the other regions may not have the same combination of environmental factors leading to a heightened risk for wildfires, making the Southwest particularly vulnerable.
