The atmospheric CO2 anomaly resulting from the combined effect of the ocean
and post-fire carbon sinks is shown in fig. S3D. Radiative forcing from CO2 and CH4
during years 0-80 (and reflecting this atmospheric CO2 trajectory) was 1.6 ± 0.8 W m-2.

For this longer interval, our error estimate includes the components described above for
year 1 as well as an additional 20% reflecting uncertainty introduced from estimating the
post-fire atmospheric greenhouse gas trajectory.
