Demonstrating climate change using the ggplot2 R package to create a tornado plot (CC224)

June 23, 2022 • PD Schloss • 1 min read

Pat creates a ‘tornado plot’ depicting climate change using the ggplot2 R package by plotting the temperature anomaly for April and October by year. The data depicted are monthly temperature anomalies by month using NASA’s GISS data using tools from the ggplot2 R package. This figure shows the deviation in annual global mean temperatures from the normalized temperatures of 1951 to 1980 as a series of line segments created using ggplot2’s geom_segment function. The lines are colored according to the size of the temperature anomaly. All of this is done in R with the help of RStudio.
