Persistent multi-decadal Greenland temperature fluctuation through the last millennium
International audience Future Greenland temperature evolution will affect melting of the ice sheet and associated global sea-level change. Therefore, understanding Greenland temperature variability and its relation to global trends is critical. Here, we reconstruct the last 1,000 years of central Gr...
