Impact of Climate Change on the Frequency of Wildfire----Taking California as Example
Abstract
Based on the analysis of various data over the years, this paper analyzes whether the increase of warm season will affect the fire frequency, intensity and fire season length. Combined with the specific situation and data of mountain wildfires in California in the past decade, the causes of wildfires in California are obtained, that is, climate change plays an important role in forest fires. And greenhouse gas emissions significantly affect the fuel dryness (CWD) and fuel availability (AET) in mountain forests from two aspects of reducing rainfall and increasing temperature, thereby increasing the probability of mountain fires. After that, through the analysis of other human factors, the indispensable influence of human activities on wildfires was confirmed.
