List of data provided

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

This dataset contains:

Top panel:

- Cumulative global total anthropogenic carbon dioxide emissions (1850-2019)

- Global surface temperature increase relative to 1850-1900 (1850-2019)

- Estimated human-caused warming relative to 1850-1900 (1850-2019)

- Projected global total anthropogenic carbon dioxide emissions for the five scenarios of the AR6 WGI core set of scenarios (2015-2050)

- Assessed global surface temperature increase relative to 1850-1900 for the five scenarios of the AR6 WGI core set of scenarios (2015-2050)

Bottom panel:

- Cumulative global total anthropogenic carbon dioxide emissions (1850-2019)
