The 8.2 ka cooling event caused by Laurentide ice saddle collapse
TLDR
This article showed that instead of being caused by the lake outburst, the event could have been caused by accelerated melt from the collapsing ice saddle that linked domes over Hudson Bay in North America.About:

TL;DR: A tripartite division of the Holocene into the Greenlandian, Northgrippian and Meghalayan stages/ages and their corresponding Lower/Early, Middle, Upper/Late subseries/subepochs, each supported by a Global Boundary Stratotype Section and Point (GSSP) is reported in this article.

TL;DR: A formal subdivision of the Holocene series/epochronology was proposed by the International Commission on Stratigraphy (ICS) as discussed by the authors, with three new stages/ages, two underpinned by Global Boundary Stratotype Sections and Points (GSSPs) in an ice core, and a third in a speleothem.

Constraining the Variability of the Atlantic Meridional Overturning Circulation During the Holocene
Jörg Lippold,Frerk Pöppelmeier,Finn Süfke,Marcus Gutjahr,Tyler J. Goepfert,Patrick Blaser,Oliver Friedrich,Jasmin M. Link,Lukas Wacker,Stefan Rheinberger,Samuel L Jaccard +10 more
TL;DR: In this article, the authors assess the variability of the Atlantic Meridional Overturning Circulation (AMOC) during the Holocene based on a marine sediment core retrieved from the deep northwest Atlantic, which sensitively recorded large-scale deglacial transitions in deep water circulation.

Physical processes of cooling and mega-drought during the 4.2 ka BP event: results from TraCE-21ka simulations
TL;DR: In this paper, the authors investigated the spatiotemporal characteristics, the possible causes and related physical processes of the event using a set of long-term climate simulations, including one all-forcing experiment and four single-forcing experiments.

Early Holocene Thermal Maximum recorded by branched tetraethers and pollen in Western Europe (Massif Central, France)
Céline Martin,Céline Martin,Guillemette Ménot,Nicolas Thouveny,Odile Peyron,Valérie Andrieu-Ponel,Vincent Montade,Vincent Montade,Nina Davtian,Maurice Reille,Edouard Bard +10 more
TL;DR: In this paper, an analysis of the sedimentary record from Lake St Front, in the Massif Central (France) has been carried out to identify a shift in brGDGT sources through the Holocene, which required removing terrigenous influences from the temperature signal.

GLOBAL GLACIAL ISOSTASY AND THE SURFACE OF THE ICE-AGE EARTH: The ICE-5G (VM2) Model and GRACE
TL;DR: The impact of the changing surface ice load upon both Earth's shape and gravitational field, as well as upon sea-level history, have come to be measurable using a variety of geological and geophysical techniques.

Sea level and global ice volumes from the Last Glacial Maximum to the Holocene.
TL;DR: From ∼1,000 observations of sea level, allowing for isostatic and tectonic contributions, this work quantified the rise and fall in global ocean and ice volumes for the past 35,000 years and provides new constraints on the fluctuation of ice volume in this interval.

Forcing of the cold event of 8,200 years ago by catastrophic drainage of Laurentide lakes

TL;DR: In this article, the authors argue that this cooling event was forced by a massive outflow of fresh water from the Hudson Strait, based on the estimates of the marine 14C reservoir for Hudson Bay which, in combination with other regional data, indicate that the glacial lakes Agassiz and Ojibway (originally dammed by a remnant of the Laurentide ice sheet) drained catastrophically ∼8,470 calendar years ago; this would have released >1014 m3 of freshwater into the Labrador Sea.
