Climate spiral

An early Ed Hawkins climate spiral portrays global warming,[Note 1] the spiral's growing radius indicating how temperature has increased since 1850.[1]
Final frame of a climate spiral[2][Note 1]

A climate spiral (sometimes referred to as a temperature spiral[3][4]) is an animated data visualization graphic designed as a "simple and effective demonstration of the progression of global warming", especially for general audiences.[5]

The original climate spiral was published on 9 May 2016 by British climate scientist Ed Hawkins to portray global average temperature anomaly (change) since 1850.[6] The visualization graphic has since been expanded to represent other time-varying quantities such as atmospheric CO2 concentration,[3] carbon budget,[3] and arctic sea ice volume.[7][8]
