Summary[edit]

Description
English: Screenshot of a frame of a Climate spiral Data visualization of Earth's Arctic sea ice volume from 1979 to 2017.
  • Independent variable is time:
  • Months are represented by angles about a center point
  • Years are represented by evolving colors as the years pass
  • Dependent variable is Earth's arctic sea ice volume, represented by distance from the center point, which generally becomes smaller as time progresses due to shrinkage of polar sea ice volume. Curve is "lopsided" due to seasonal (winter-summer) variations.
