TL;DR: In this paper, the authors measured 14 CH4 and 14 CO content in glacial firn with unprecedented precision to advance understanding of the in situ 14 C component, showing that most (4 99%) of the 14 CO is rapidly lost from shallow Summit firn to the atmosphere.

Phase 4 of PAGES 2k: Hydroclimate of the Common Era
Benjamin J. Henley,Anais Orsi,Helen McGregor,Matthew Jones,Georgina Falster,Lukas Jonkers,Rengaswamy Ramesh,S. Eggleston,Z Weng +8 more
TL;DR: The PAGES 2k network as mentioned in this paper has been used to reconstruct hydroclimatic variability over the Common Era, from local to global spatial scales, at sub-annual to multi-centennial time scales, developing a processlevel understanding of past hydroclimate events and variability.

Warm Temperature Anomalies Associated with Snowfall in Antarctica
TL;DR: In this paper , the authors used the polar-oriented atmospheric model MAR to study the statistical difference between average and snowfall-weighted temperatures in Antarctica and found that most of Antarctica experiences a warming scaling with snowfall, although with strongest warming at sites with usually low accumulation.

TL;DR: In this paper , the authors present a gas-phase proxy that directly samples a component of the large-scale atmospheric circulation, namely synoptic-scale pressure variability, from the West Antarctic Ice Sheet (WAIS) Divide ice core.
