Marine20—The Marine Radiocarbon Age Calibration Curve (0–55,000 cal BP)
Timothy J Heaton,Peter Köhler,Martin Butzin,Edouard Bard,Ron W Reimer,William E. N. Austin,Christopher Bronk Ramsey,Pieter Meiert Grootes,Konrad A Hughen,Bernd Kromer,Paula J. Reimer,Jess F. Adkins,Andrea Burke,Mea S Cook,Jesper V. Olsen,Luke C Skinner +15 more
TL;DR: Marine20 as mentioned in this paper is an update to the internationally agreed marine radiocarbon age calibration curve that provides a non-polar global-average marine record of radioccarbon from 0 −55 cal kBP and serves as a baseline for regional oceanic variation.

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.
Enhanced chemical weathering as a geoengineering strategy to reduce atmospheric carbon dioxide, supply nutrients, and mitigate ocean acidification
Jens Hartmann,A. Joshua West,Philip Renforth,Peter Köhler,Christina L. De La Rocha,Dieter Wolf-Gladrow,Hans H. Dürr,Jürgen Scheffran +7 more
TL;DR: Enhanced weathering is an integral part of both the rock and carbon cycles and is being affected by changes in land use, particularly as a result of agricultural practices such as tilling, mineral fertilization, or liming to adjust soil pH as mentioned in this paper.

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.
