| Zusammenfassung |
| The Mediterranean is considered as an area which will be affected strongly
by current climate change. However, temperature records for the past
centuries which can contribute to a better understanding of future climate
changes are still sparse for this region. Carbon isotope chronologies from
tree-rings often mirror temperature history but their application as climate
proxies is difficult due to the influence of the anthropogenic change in
atmospheric CO2 on the carbon isotope fractionation during
photosynthetic CO2 uptake. We tested the influence of different
correction models accounting for plant response to increased atmospheric
CO2 on four annually resolved long-term carbon isotope records (between
400 and 800 yr) derived from Corsican pine trees (Pinus nigra ssp. laricio) growing at
ecologically varying mountain sites on the island of Corsica. The different
correction factors have only a minor influence on the main climate signals and
resulting temperature reconstructions. Carbon isotope series show strong
correlations with summer temperature and precipitation. A summer temperature
reconstruction (1448–2007 AD) reveals that the Little Ice Age was
characterised by low, but not extremely low temperatures on Corsica.
Temperatures have been to modern temperatures
at around 1500 AD. The reconstruction reveals warm summers during
1480–1520 and 1950–2007 AD and cool summers during 1580–1620 and 1820–1890 AD. |
