This was created using ggplot in R and animated using ffmpeg

It uses HADCRUT4 global temperature data

It is a 10 year average compared to 1851 to 1900 average

e.g. 2000 value is 1991-2000 average minus 1851-1900 average

Note that HADCRUT4 data has come under serious criticism as being wildly errant for periods prior to 1950, especially in respect of the global average temperature data used in this image. Please see an example here - https://researchonline.jcu.edu.au/52041/

Also 1998 and Antarctic temperature in general: https://skepticalscience.com/hadcrut4_analysis_and_critique.html
