TL;DR: In this paper, the North Greenland Eemian Ice Drilling (NEEM) ice core was extracted from folded Greenland ice using globally homogeneous parameters known from dated Greenland and Antarctic ice-core records.

TL;DR: The new North Greenland Eemian Ice Drilling (‘NEEM’) ice core is presented and shows only a modest ice-sheet response to the strong warming in the early Eemians, which was probably driven by the decreasing summer insolation.

TL;DR: In this paper, the authors used an ensemble of ten reference tracers of known atmospheric history to characterise the transport properties of the NEEM site in Northern Greenland and found that diffusivity does not vanish completely in the lock-in zone, as is commonly assumed.

A control-oriented model of the current profile in tokamak plasma
Emmanuel Witrant,E. Joffrin,Sylvain Brémond,G. Giruzzi,Didier Mazon,Oliviero Barana,Philippe Moreau +6 more
TL;DR: In this paper, a control-oriented approach to the tokamak plasma current profile dynamics is proposed based on a consistent set of simplified relationships, in particular for the microwave current drive sources, rather than exact physical modelling.

Natural and anthropogenic variations in methane sources during the past two millennia

TL;DR: High-resolution carbon isotope data for methane from two ice cores from Greenland for the past two millennia is presented and it is found that the δ13C content underwent pronounced centennial-scale variations between 100 bc and ad 1600.
