Climate change between the mid and late Holocene in the northern high latitudes : Part I: Survey of temperature and precipitation proxy data

We undertake a study in two parts, where theoverall aim is to quantitatively compare results from climateproxy data with results from several climate model simulationsfrom the Paleoclimate Modelling IntercomparisonProject for the mid-Holocene period and the pre-industrial,conditions for the pan-arct...
