Project Part 1

Preparing the Climate Change Impacts data for plotting.

1. I downloaded Climate Change Impacts data from Our World in Data. I selected this data because I am interested in climate change and the effect it is having on our world from 1965 to 2021.

2. This is the link to the data.

3. The following code chunk loads the packages I will use to read in and prepare the data for analysis.

library(tidyverse)
library(dplyr)

4. Read the data in

climate_change <- 
  read_csv(here::here("_posts/2022-05-03-project-part-1/climate_change.csv"))

5. Use glimpse to see the names and types of the columns

glimpse(climate_change)

6. Use output from glimpse to prepare the data for analysis.

• Change the name of the first column to Region and the 12th column to Temperature_anomaly

• Use filter to extract the rows that I want to keep: date >= 1965-01-15 and Region= world

• Select the columns to keep: Region, Date, Temperature_anomaly

• Assign the output to monthly_temperature_anomaly

• Display the first 10 rows of monthly_temperature_anomaly

monthly_temperature_anomaly <- climate_change %>%
  rename(Region = 1, Temperature_anomaly = 12) %>% 
  filter(Date >= "1965-01-15", Region == "World") %>%
  select(Region, Date, Temperature_anomaly)

monthly_temperature_anomaly
