| Zusammenfassung |
| High-resolution ice core records from Antarctica reveal multi-decadal scale variability in
atmospheric CO2 during the Late Pre-industrial Holocene. The mechanisms behind these
variations remain elusive, but are important in constraining natural carbon-climate feedbacks.
Additionally, recent data suggesting a Pre-industrial anthropogenic influence on
atmospheric CO2 (Nevle, 2011) conflict with results of coupled climate-carbon models
(Pongratz, 2011). The stable isotopic composition of carbon dioxide (δ13C of CO2)
offers a tool to determine the nature and strength of carbon dioxide sources to the
atmosphere.
