| Zusammenfassung |
| In view of the current global warming the short interglacial periods receive more and more
attention within the paleoclimate community, especially focused on the Marine Isotope Stage
5.5, as a couple of terrestrial and marine archives indicate warmer than present conditions
during this time period. Accordingly, MIS 5.5 is often regarded as a first order analogue for a
warmer world in the future.
The stable carbon isotopic ratio measured on CO2 from deep Antarctic ice cores
bears crucial information to constrain changes in the global carbon cycle, and, thus,
also coupled climate models and paleo reconstructions from marine or terrestrial
archives.
We present a reconstruction of the stable carbon isotope changes of CO2 during Marine
Isotope Stage 5.5 measured on the EPICA Dome C core. A first hand interpretation is
provided along with a comparison to the Holocene. |
