TL;DR: The Greenland ice core from NorthGRIP (NGRIP) contains a proxy climate record across the Pleistocene-Holocene boundary of unprecedented clarity and resolution, which enables the base of the Holocene, as reflected in the first signs of climatic warming at the end of the Younger Dryas/Greenland Stadial 1 cold phase, to be located with a high degree of precision as discussed by the authors.

TL;DR: 14C results from Lake Suigetsu, Japan are reported, which provide a comprehensive record of terrestrial radiocarbon to the present limit of the 14C method, and gives information on the connection between global atmospheric and regional marine radiOCarbon levels.

TL;DR: In this article, the best modern analogues method was tested with 285 surface pollen spectra, and then applied to the 47,000 years pollen profile from Lake Mikata, Central Japan Both pollen taxa percentages and plant functional type affinity scores were used in the reconstruction of six climate variables.

TL;DR: Pollen records from the annually laminated sediment sequence in Lake Suigetsu, Japan, suggest a sequence of climate changes during the Last Termination that resembles that of the North Atlantic region but with noticeable differences in timing.

TL;DR: In this article, a total of 15 organic-rich sediment samples, obtained from sites in Corsica and the Southern European Alps, was treated using both dense-media separation and the conventional preparation method in order to compare the relative efficiencies of the two methods.
