Code associated with "Climate-linked escalation of societally disastrous wildfires"

The code is broken into three separate scripts00_Functions_disasters.R contains custom functions used throughout.01_Data organisation_disasters.R contains data processing steps, most notably categorising disaster events as major or minor based on whether they (i) were in the top 200 economic events (measured as a percentage of contemporaneous national GDP), or (ii) caused at least 10 fatalities. We are contractually prevented from providing the input NatCatSERVICE data used by this script, but the partly redacted output ("disasters_major_minor.csv") is available in the data folder, and is used as the foundation of subsequent analyses02_Analysis_disasters.R contains code to run the main analyses, including trends in major economic and major fatality events, (2) analyses of geographic distribution of major disasters, and (3) climatic correlates of major disasters.

本代码分为三个独立脚本：
00_Functions_disasters.R 包含全流程通用的自定义函数。
01_Data organisation_disasters.R 包含数据处理流程，其中最核心的环节是基于两项标准将灾害事件划分为重大灾害与一般灾害：(i) 跻身按当期本国GDP占比衡量的前200项经济损失灾害事件，或(ii) 造成至少10人死亡。受合同约束，我们无法提供本脚本所使用的输入数据NatCatSERVICE（NatCatSERVICE），但经部分脱敏后的输出文件"disasters_major_minor.csv"已存放于数据文件夹中，并作为后续所有分析的基础。
02_Analysis_disasters.R 包含执行核心分析的代码，具体涵盖：(1) 重大经济损失灾害与重大人员伤亡灾害的趋势分析，(2) 重大灾害的地理分布特征分析，以及(3) 重大灾害的气候相关因素分析。
