The variability in the carbon sinks as reconstructed
for the last 1000 years. Geophysical Research Letters , 26, 1437-1441,
1999.


The atmospheric CO2 and delta C-13 records for the last millennium have
been analyzed to reconstruct the evolution and the temporal variability
in the terrestrial and oceanic carbon sinks and to identify natural
variations in the marine carbon cycle.
