globalTemp

globalTemp is a data package that is meant to provide access to the data used for creating the famous climate spiral video, released by NASA.

This vizualisation shows monthly global temperature anomalies between the years 1880 and 2021. Anomalies are calculated as the differences between the measured temperatured and the average temperature for period 1951 to 1980. Blues indicate cooler temperatures, while reds show warmer temperatures. It is famous because it shows clearly the impact of man-made climate change on the global temperature.

Installation

You can install the released version of globalTemp from CRAN with:

install.packages("globalTemp")

And the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("ABohynDOE/globalTemp")

Example

This is a basic example that shows you how to build a graph of the temperature change, using the package:

library(globalTemp)
library(ggplot2)
library(dplyr)
#> 
#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':
#> 
#>     filter, lag
#> The following objects are masked from 'package:base':
#> 
#>     intersect, setdiff, setequal, union

global %>%
  group_by(year) %>%
  summarise(mean_temp = mean(temperature)) %>%
  ggplot(aes(x = year, y = mean_temp)) +
  geom_point() +
  geom_line() +
  geom_hline(yintercept = 0) +
  labs(
    x = "Average temperature anomaly",
    y = "Year"
  ) +
  theme_minimal(base_size = 20)
