The visualization presents monthly global temperature anomalies between the years 1880-2022. Temperature anomalies are deviations from a long term global average. In this case the period 1951-1980 is used to define the baseline for the anomaly. These temperatures are based on the GISS Surface Temperature Analysis (GISTEMP v4), an estimate of global surface temperature change.



The term 'climate spiral' describes an animated radial plot of global temperatures. Climate scientist Ed Hawkins from the National Centre for Atmospheric Science, University of Reading popularized this style of visualization in 2016.



The Goddard Institute of Space Studies (GISS) is a NASA laboratory managed by the Earth Sciences Division of the agency’s Goddard Space Flight Center in Greenbelt, Maryland. The laboratory is affiliated with Columbia University’s Earth Institute and School of Engineering and Applied Science in New York.
