Watching the Land Temperature Bell Curve Heat Up (1950-2020)

Ask a Question

  • This brief video is an animation of land temperature anomaly distributions through time from 1950 to 2020.
  • Students will see that in the seventy-year period, hotter days have increased and colder days have decreased in regularity.
Teaching Tips


  • The data clearly displays an increase in warmer than normal temperatures on land over time.
  • There is a link in the description to download the video and learn more about the methodology.

Additional Prerequisites

  • Students should know how to read a bell curve.
  • Students should know the terms normal distribution and anomaly.

    • This is a quick 30 second video but paints a clear picture of rising surface temperatures.
