Climate spiral (original) (raw)

A climate spiral (sometimes referred to as a temperature spiral) is an animated data visualization graphic designed as a "simple and effective demonstration of the progression of global warming", especially for general audiences. 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. The visualization graphic has since been expanded to represent other time-varying quantities such as atmospheric CO2 concentration, carbon budget, and arctic sea ice volume.
