Summary

Description
English: w:Warming stripes juxtaposing annual average temperatures in the northern and southern hemispheres (1880-2018).

Specific notes:

  • Top panel: Northern Hemisphere 1880-2018, annual (Jan-Dec), reference period 1901-2000 (average temp determines boundary between blue and red stripes), Land and Ocean.
  • Bottom panel: Southern Hemisphere 1880-2018, annual (Jan-Dec), reference period 1901-2000 (average temp determines boundary between blue and red stripes), Land and Ocean.
  • Important: Graphics present temperature anomaly away from respective average values over the reference period 1901-2000. They show temperature change. Accordingly, a hue in one diagram does not necessarily represent the same absolute temperature as the same hue in the other diagram
  • Panels are vertically aligned to enable year-by-year comparison
  • In the Northern Hemisphere, one recent year's value exceeded the color scale. Southern hemisphere's values remained within range of color scale.

General notes:

  • Credit for general concept of w:warming stripes: climate scientist Ed Hawkins, w:University of Reading, U.K.
  • Data values are visualized using color rather than locations of points on a graph.
  • The average temperature in the reference period (1901-2000 for both panels) determines boundary between blue and red.
  • Horizontal scale is time, from 1880 (left) to 2018 (right).
  • Each hue (up to 8 blue and 8 red) covers a temperature range of 0.15 degrees Celsius.
