Figure subpanels
The figure has two panels, with data provided for all panels in the underlying chapter figures. 

List of data provided
Proxy-based and model-simulated estimates of global surface temperature agree across multiple reference periods.

Data provided in relation to figure
Panel a:
- Data file: BoxTS_2_Fig_2a.csv:  The 'reconstructed temperature' is the same as the global surface temperature in BoxTS.2 Fig. 1. The 'simulated temperature' is the average values for model outputs shown in Fig 3.44a

Panel b:
- The data for BoxTS.2 Fig 2b uses the same those in Fig 3.2c, except the TS shows 10-year smooth whereas Fig 3.2c shows 20-year smooth, and the TS shows the averages (with 5-95% ranges) of the 32 simulations that are shown separately in Fig. 3.2c.

Notes on reproducing the figure from the provided data

Caption for Box TS.2, Figure 2 from the Technical Summary of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6)


Global surface temperature as estimated from proxy records (reconstructed) and climate models (simulated). The intent of this figure is to show the agreement between observations and models of global temperatures during paleo reference periods. (a) For individual paleoclimate reference periods. (b) For the last millennium, with instrumental temperature (AR6 assessed mean,10-year smoothed). Model uncertainties in (a) and (b) are 5-95% ranges of multi-model ensemble means; reconstructed uncertainties are 5-95% ranges (medium confidence) of (a) midpoints and (b) multi-method ensemble median. {, Figure 2.34, Figure 3.2c, Figure 3.44}
