What will be the difference in the Earth's decadal average global surface temperature in 2091 to 2100 as compared to 1881 to 1890?

The outcome will be determined using data as reported by the UK's Met Office Hadley Centre (UK Met Office). To view the data, download the "Annual" file under "CSV" for "Global (NH+SH)/2" in the "Summary series" table. The difference will be determined by subtracting the "Anomaly (deg C)" average for 1881 to 1890 from the average for 2091 to 2100. The decadal average for 1881 to 1890 was -0.389351564°C. Please note that the data use 1961-1990 as a baseline, hence the negative figure for 1881-1890. .
