List of data provided

---------------------------------------------------

Global surface temperature, relative to 1850 - 1900 for:

Panel a: 

- 1000 to 1900 CE - from PAGES 2k Consortium (modified from the version 2019: 10.1038/s41561-019-0400-0)

- 1850 to 2020 from AR6 assessed mean (same as Figure 2.11c).

Panel c: 

- Annual and decadal means from instrumental data for 1850–2020, along with the uncertainty range from HadCRUT5.

---------------------------------------------------

Data provided in relation to figure

---------------------------------------------------

Panel a:

- Data file: Figure_2_11a-PAGES_2k_Consortium.csv (yearly data, 1000 to 1900); relates to the center part of the figure showing global surface temperature relative to 1850 -1900. (bold solid green line, column 2, median 10-yr smooth adjusted (+0.37°C), thin solid green lines: 5th (column 3) and 95th (column 4) percentiles of the ensemble members).

- Data file: Figure2_11_panel_a.csv (yearly data, 1850 to 2020); relates to the right part of the figure showing global temperature anomaly AR6 assessed mean. (bold solid violet line, column 2)

Panel c: 

- Data file: Figure_2_11c-land_and_ocean_time_series.csv (yearly data, 1850 to 2020); relates to the upper part of the figure showing global surface temperature relative to 1850 -1900. (Land, column 2, red line; Ocean, column 3, blue line).

- Data file: Figure_2_11c-lower_panel.csv, (annual and decadal mean, 1850 to 2020); relates to the lower part of the figure. (black line, column 2, HadCRUT 5.0; cyan line, column 3, NOAA Global Temp; pink line, column 4, Berkeley Earth; orange line, column 5, Kadow et al.; grey shadow, columns 6 and 7, HadCRUT confidence limit)
