Global Holocene Spatial and Temporal Climate Variability

Project Description
In the GHOST project, we intend to explore the climate evolution of the entire Holocene. Our perspective consists of two baselines: the worldwide distribution of existing, reedited, and new collected marine Alkenone temperature data; and actual but low resolution general circulation models with high computational efficiency, de- signed for long term paleoclimate studies. In order to increase spatial coverage of Holocene time series we will concentrate on marine sediments with relatively low but highest achievable resolution in the range of 50 to 200 years. Both, the data reconstruc- tion and the modelling efforts within this project, aim to investigate three-dimensional spatial-temporal patterns, i.e. two dimensions (the Earth's surface) and the time as third dimension. The advanced analysis of spatial and temporal variability in the data and in the model should enable the comprehension of climate changes detected in the data and the verification of climate variability observed in the model. Pattern analysis will provide a better understanding of the heterogenity in Holocene warming or cool- ing and the related mechanisms. The extension of the Holocene climate simulation into the next few centuries will enable a better assessment of future climatic change, due to similarities or dissimilarities between patterns of natural and anthropogenic disturbed climates.
