List of data provided
---------------------------------------------------
Panel a
The dataset contains:
- Estimated temperature during the warmest multi-century period in at least the last 100,000 years, which occurred around 6500 years ago (4500 BCE), multi-centennial average, from AR6 WGI Chapter 2
- Global surface temperature change time series relative to 1850-1900 for 1-2020 from:
• 1-2000 CE reconstruction from paleoclimate archives, decadal smoothed, from PAGES2k Consortium (2019, DOI: 10.1038/s41561-019-0400-0)
• 1850-2020 CE, observations, decadal smoothed, from AR6 WGI Chapter 2 assessed mean
Panel b:
The dataset contains global surface temperature change time series relative to 1850-1900 for 1850-2020 from simulations from the sixth phase of the Coupled Model Intercomparison Project (CMIP6) and observations:
- CMIP6 historical+ssp245 simulations (simulations with human and natural forcing, 1850-2019)
- CMIP6 hist-nat simulations (simulations with natural forcing, 1850-2019)
- Global Surface Temperature Anomalies (GSTA) relative to 1850-1900 from observations assessed in IPCC AR6 WG1 Chapter 2 (1850-2020)
