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.
