Mauna Loa Temperature Graph

Updated: Feb 14

This graph was made by a person using data from NOAA’s Global Monitoring Lab. The person made the graph to show what happens when you average many years of data.



Examine the different data lines.

  • The dark blue line connects data points for each year's average data.

  • The red line connects data points for a 5-year average.

  • The green line connects data points for a 15-year average.

  • The light blue line shows the trend for all the data.


What happens as you average more years’ worth of data?
