Description
English: Screenshot of a frame of a Climate spiral Data visualization of Earth's atmospheric CO2 (carbon dioxide) concentration beginning in 1958.
  • 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 atmospheric CO2 concentration represented by distance from the center point, which expands smoothly due to generally smooth growth of CO2 concentration.
