Global Temperature Anomalies from 1880 to 2024
Scientific consulting by: Gavin A. Schmidt Visualizations by: Mark SubbaRao

Original source page, titled "Global Temperature Anomalies from 1880 to 2023" Visualizations by Mark SubbaRao, includes the descriptions:

• This color-coded map in Robinson projection displays a progression of changing global surface temperature anomalies. Normal temperatures are shown in white. Higher than normal temperatures are shown in red and lower than normal temperatures are shown in blue. Normal temperatures are calculated over the 30 year baseline period 1951-1980. The maps are averages over a running 24 month window. The final frame represents global temperature anomalies in 2023. Scale in degrees Celsius and Fahrenheit.

• This color-coded map in Robinson projection displays a progression of changing global surface temperature anomalies. Normal temperatures are shown in white. Higher than normal temperatures are shown in red and lower than normal temperatures are shown in blue. Normal temperatures are calculated over the 30 year baseline period 1951-1980. The final frame represents the 5 year global temperature anomalies from 2018-2022. Scale in degrees Celsius and Fahrenheit.

• This color-coded map in Robinson projection displays a progression of changing global surface temperature anomalies. Normal temperatures are shown in white. Higher than normal temperatures are shown in red and lower than normal temperatures are shown in blue. Normal temperatures are calculated over the 30 year baseline period 1951-1980. The final frame represents the 5 year global temperature anomalies from 2017-2021. Scale in degrees Celsius.

Original source page, titled "Global Temperature Anomalies from 1880 to 2020" Visualizations by Lori Perkins, includes the descriptions:

• This color-coded map in Robinson projection displays a progression of changing global surface temperature anomalies. Normal temperatures are the average over the 30 year baseline period 1951-1980. Higher than normal temperatures are shown in red and lower than normal temperatures are shown in blue. The final frame represents the 5 year global temperature anomalies from 2016-2020. Scale in degrees Celsius.

Original source page, titled "Global Temperature Anomalies from 1880 to 2019" Visualizations by Lori Perkins, includes the descriptions:

• "This color-coded map in Robinson projection displays a progression of changing global surface temperature anomalies. Normal temperatures are the average over the 30 year baseline period 1951-1980. Higher than normal temperatures are shown in red and lower than normal temperatures are shown in blue. The final frame represents the 5 year global temperature anomalies from 2015-2019. Scale in degrees Celsius."
• "These calculations produce the global average temperature deviations from the baseline period of 1951 to 1980."
