    From the article:

    An international research collaboration (EGRIP) headed by ice core scientists from the University of Copenhagen has attained their goal of drilling to the bottom of the ice sheet. It marks the first time that this has been achieved in an ice stream, where vast amounts of ice slide coastwards. The breakthrough could be critical for understanding and projecting rising sea levels.

    ...

    Towards the base, the ice is more than 120,000 years old and dates back to the last interglacial period, a time when the atmospheric temperature above Greenland was 5°C warmer than today.

    ...

    Analyses of the last ice cores will begin in fall, when the research group returns to Copenhagen. The EGRIP ice core is stored in the Danish ice core repository in the Copenhagen suburb Brøndby together with most of the deep Greenland ice cores. Samples from the ice cores drilled the previous years have been analyzed in more than 30 laboratories and the first 53 papers have been published.

    Thanks for this, really interesting and very curious to see how it's going to affect our current climate models. anxious but excited
