The Last Interglacial (LIG, 129-116 thousand of years BP, ka) represents a test bed for climate model feedbacks in warmer-than-present high latitude regions. However, mainly because aligning different palaeoclimatic archives and from different parts of the world is not trivial, a spatio-temporal picture of LIG temperature changes is difficult to obtain. Here, we have selected 47 polar ice core and sub-polar marine sediment records and developed a strategy to align them onto the recent AICC2012 ice core chronology. We provide the first compilation of high-latitude temperature changes across the LIG associated with a coherent temporal framework built between ice core and marine sediment records. Our new data synthesis highlights non-synchronous maximum temperature changes between the two hemispheres with the Southern Ocean and Antarctica records showing an early warming compared to North Atlantic records. We also observe warmer than present-day conditions that occur for a longer time period in southern high ... : This dataset concerns the new synthesis of high-latitude temperature anomalies during the Last Interglacial published by Capron et al. 2014. It contains:- the information of marine sediment and ice core sites included in the study: name, latitude, longitude, elevation, information of temperature reconstruction, modern temperature value (from WOA98 and core top, if available)- temperature anomalies and 2 sigma errors for 4 time slices (130 ka, 125 ka, 120 ka, 115 ka) using WOA98 values as modern reference- temperature anomalies and 2 sigma errors for 4 time slices (130 ka, 125 ka, 120 ka, 115 ka) using core top SST values as modern referenceAge pointers defined in marine sediment cores are given in Table A2 available online as a supplement of the paper. ...
