Summary: | Greenland ice cores tell story of warm spell The analysis of ice cores extracted at the NEEM 1 ice-drilling site has enabled an international team of scientists to reconstruct Greenland's climate history over the past 130,000 years, with the participation in France of CNRS, CEA, UVSQ, Université Joseph Fourier 2 and IPEV. For the first time in the Arctic, the researchers have succeeded in retrieving ice formed during the last interglacial period, 130,000 to 125,000 years ago, which was marked by significant warming in that region. Their findings show that the Greenland ice sheet only contributed 2 meters to the 4—8 meters of sea level rise observed during that period. Published on 24 January in Nature, this study provides valuable information about the relationship between climate and sea level rise. NEEM is an international ice-drilling project aimed at extracting ice cores in northwest Greenland. Its goal was to obtain, for the first time in the Arctic, samples reaching back 130,000 years to the last interglacial period, the Eemian, a warm episode in Earth's history. Led by the University of Copenhagen and involving 14 countries including France, the NEEM team drilled more than 2.5 km down to the bedrock in two years, between 2010 and 2012. They extracted the first complete record of the Eemian, providing estimates of |
