Associated with the long - term predictability of soil water and internal slow vegetation adjustment timescales, we also found evidence for decadal predictability of
total vegetation carbon and fire season length in the CESM experiments.
Time series of total water storage (color in upper panels), fire season length (lines in upper and bottom panels), and
total vegetation carbon (color in bottom panels) averaged over the Northern US and Southern US / Mexico regions in the pre-industrial control simulation.
The orange line corresponds to the lag correlation coefficients between
the total vegetation carbon and the annual fire season length (vegetation leads in the positive lags).
Lead - lag correlation between variations in annual mean total water storage,
total vegetation carbon, and annual fire season length over the Northern US and the Southern US / Mexico regions in the control simulation.

Forests and other land
vegetation currently remove up to 30 percent of human
carbon dioxide emissions from the atmosphere during photosynthesis, but thanks to this latest study, experts now know that we have tropical forests to thank for a great deal of this work - absorbing a whopping 1.4 billion metric tons of CO2 out of a
total total global absorption of 2.5 billion metric tons.
Global
vegetation fire emissions typically constitute a third of
total releases of
carbon dioxide, the main heat - trapping emission, annually (1).
Recall that annual uptake of
carbon is about two orders of magnitude smaller than the
total carbon amount stored in
vegetation.
The amount of
carbon that would need to be removed from the atmosphere and stabilized in soils, in addition to the amount required to compensate for ongoing emissions, to attain pre-industrial levels is equivalent to approximately one - half of the
total carbon in all of Earth's
vegetation.
The soils of the world contain more
carbon than the combined
total amounts occurring in
vegetation and the atmosphere.
This graph shows
total carbon content, rather than fluxes — think of it as the integral of the previous graph, but discounting
vegetation carbon.
Decadal climate prediction of annual mean variations in
total water storage (left),
vegetation carbon (center), and fire season length (right panels) over the Northern US.
The half life time of the accumulation in mass of CO2 in the atmosphere is entirely different of the half life time of the accumulation in % in the atmosphere of the emissions, which is governed by the
total carbon cycles between air and oceans /
vegetation.
