| Zusammenfassung |
| The impacts of climate change and increasing atmospheric CO2
concentration on the terrestrial uptake of carbon dioxide since 1860 in the
Canadian province of British Columbia are estimated using the process-based
Canadian Terrestrial Ecosystem Model (CTEM). Model simulations show that
these two factors yield an enhanced carbon uptake of around 44 gC m−2 yr−1
(or equivalently 63 gC m−2 yr−1 over the province's
forested area), during the 1980s and 1990s, and continuing into the 2000s. About
three-quarters of the simulated sink enhancement in our study compared to
pre-industrial conditions is attributed to changing climate, and the rest is
attributed to increase in CO2 concentration. The model response to
changing climate and increasing CO2 is corroborated by comparing
simulated stem wood growth rates with ground-based measurements from
inventory plots in coastal British Columbia. The simulated sink is not an
estimate of the net carbon balance because the effects of harvesting, insect
disturbances and land-use change are not considered. |
