title: Simulated agricultural subsistence, timing of transition, and percentage of immigrant farmers

description: Farming and herding were introduced to Europe from the Near East and Anatolia; there are, however, considerable arguments about the mechanisms of this transition. Were it the people who moved and either outplaced, or admixed with, the indigenous hunter-gatherer groups? Or was it material and information that moved---the Neolithic Package---consisting of domesticated plants and animals and the knowledge of their use? The latter process is commonly referred to as cultural diffusion and the former as demic diffusion. Despite continuous and partly combined efforts by archaeologists, anthropologists, linguists, palaeontologists and geneticists, a final resolution of the debate has not yet been reached. In the present contribution we interpret results from the Global Land Use and technological Evolution Simulator (GLUES). GLUES is a mathematical model for regional sociocultural development, embedded in the geoenvironmental context, during the Holocene. We demonstrate that the model is able to realistically hindcast the expansion speed and the inhomogeneous space-time evolution of the transition to agropastoralism in western Eurasia. In contrast to models that do not resolve endogenous sociocultural dynamics, our model describes and explains how and why the Neolithic advanced in stages. We uncouple the mechanisms of migration and information exchange and also of migration and the spread of agropastoralism. We find that: (1) An indigenous form of agropastoralism could well have arisen in certain Mediterranean landscapes, but not in Northern and Central Europe, where it depended on imported technology and material. (2) Both demic diffusion by migration and cultural diffusion by trade may explain the western European transition equally well. (3) Migrating farmers apparently contribute less than local adopters to the establishment of agropastoralism. Our study thus underlines the importance of adoption of introduced technologies and economies by resident foragers.

title: Holocene experiment with coupled atmosphere-ocean-model ECHAM5/MPI-OM

description: Changes in the Earth's orbit lead to changes in the seasonal and meridional distribution of insolation. We quantify the influence of orbitally induced changes on the seasonal temperature cycle in a transient simulation of the last 6000 years – from the mid-Holocene to today – using a coupled atmosphere-ocean general circulation model (ECHAM5/MPI-OM) including a land surface model (JSBACH).The seasonal temperature cycle responds directly to the insolation changes almost everywhere. In the Northern Hemisphere, its amplitude decreases according to an increase in winter insolation and a decrease in summer insolation. In the Southern Hemisphere, the opposite is true.Over the Arctic Ocean, decreasing summer insolation leads to an increase in sea-ice cover. The insulating effect of sea ice between the ocean and the atmosphere leads to decreasing heat flux and favors more "continental" conditions over the Arctic Ocean in winter, resulting in strongly decreasing temperatures. Consequently, there are two competing effects: the direct response to insolation changes and a sea-ice insulation effect. The sea-ice insulation effect is stronger, and thus an increase in the amplitude of the seasonal temperature cycle over the Arctic Ocean occurs. This increase is strongest over the Barents Shelf and influences the temperature response over northern Europe.We compare our modeled seasonal temperatures over Europe to paleo reconstructions. We find better agreements in winter temperatures than in summer temperatures and better agreements in northern Europe than in southern Europe, since the model does not reproduce the southern European Holocene summer cooling inferred from the paleo reconstructions. The temperature reconstructions for northern Europe support the notion of the influence of the sea-ice insulation effect on the evolution of the seasonal temperature cycle.

title: Solar sensitivity experiments for the pre-industrial time period using the comprehensive global climate model CCSM3 (Community Climate System Model 3)

description: The Southern Hemisphere Westerly Winds (SWW) constitute an important zonal circulation that influences large-scale precipitation patterns and ocean circulation. Variations in their intensity and latitudinal position have been suggested to exert a strong influence on the CO2 budget in the Southern Ocean, thus making them a potential factor affecting the global climate. The possible influence of solar forcing on SWW variability during the Holocene is addressed. Solar sensitivity experiments with a comprehensive global climate model (CCSM3) are carried out to study the response of SWW to solar variability. In addition, It is shown that a high-resolution iron record from the Chilean continental slope (41° S), which is interpreted to reflect changes in the position of the SWW, is significantly correlated with reconstructed solar activity during the past 3000 years. Taken together, the proxy and model results suggest that centennial-scale periods of lower (higher) solar activity caused equatorward (southward) shifts of the annual mean SWW.
description: Model runs were carried out with constant solar forcing, with the control run having a total solar irradiance (TSI) value of 1365 W/m**2 and the solar sensitivity experiments with a lower TSI value of 1363 W/m**2 (i.e. reduction by 0.15%). Pre-industrial boundary conditions were applied in all simulations following the protocol established by the Paleoclimate Modelling Intercomparison Project, Phase II (Braconnot et al., 2007, doi:10.5194/cp-3-261-2007). Three sensitivity runs with reduced solar constant and different initial conditions were branched off from the control run (Merkel et al., 2010, doi:10.1016/j.quascirev.2009.11.006). Each sensitivity run was integrated for 70 years, which is a typical timescale for the duration of solar "Grand minima" like the Wolf (1280-1350 AD), Spörer (1450-1550 AD) or Maunder (1645-1715 AD) Minimum. The choice of TSI reduction of 2 W/m**2 between solar maximum and solar minimum in the model experiments is consistent with recent observation and physics based estimates (Steinhilber et al., 2009, doi:10.1029/2009GL040142). The data provided are the ensemble mean of the three sensitivity experiments with reduced TSI. See further details for the list of parameter used in NetCDF files.

title: Transient Holocene experiments under orbital forcing using the comprehensive global climate model CCSM3 (Community Climate System Model 3)

description: The Southern Hemisphere Westerly Winds (SWW) have been suggested to exert a critical influence on global climate through wind-driven upwelling of deep water in the Southern Ocean and the potentially resulting atmospheric CO2 variations. The investigation of the temporal and spatial evolution of the SWW along with forcings and feedbacks remains a significant challenge in climate research. In this study, the evolution of the SWW under orbital forcing from the early Holocene (9 kyr BP) to pre-industrial modern times is examined with transient experiments using the comprehensive coupled global climate model CCSM3. Analyses of the model results suggest that the annual and seasonal mean SWW were subject to an overall strengthening and poleward shifting trend during the course of the early-to-late Holocene under the influence of orbital forcing, except for the austral spring season, where the SWW exhibited an opposite trend of shifting towards the equator.
description: Three transient experiments from early Holocene to pre-industrial modern times (9 kyr BP to 0 BP) under orbital forcing have been carried out using the low resolution version (T31) of the comprehensive global climate model CCSM3. By applying an acceleration (by a factor of 10) to the orbital forcing year, climate trends of the last 9000 yr, imposed by the external orbitally driven insolation changes, are represented in the experiments with only 900 simulation years. While the first transient run was initialized with the quasi-equilibrated 9 kyr BP state, the second and third transient runs used the 8.9 and 8.8 kyr BP climates from the first transient run as initial conditions at 9 kyr BP. Throughout the Holocene experiments, greenhouse gas concentrations as well as aerosol and ozone distributions were kept at pre-industrial values as prescribed by the protocol of the Paleoclimate Modelling Intercomparison Project (PMIP), Phase II (Braconnot et al., 2007, doi:10.5194/cp-3-261-2007). The data provided are the ensemble mean of the three transient runs given as decadal means.
