TLDR
In this article, the termination of humidity was spatially variable, moving towards progressively lower latitudes in Africa during the early to mid-Holocene, during which Africa was more humid than today.Abstract:
During the early to mid-Holocene, Africa was more humid than today. Precipitation reconstructions from across Africa suggest that the termination of humidity was spatially variable, moving towards progressively lower latitudes.read more

Age, extent and carbon storage of the central Congo Basin peatland complex
Greta C. Dargie,Greta C. Dargie,Simon L. Lewis,Simon L. Lewis,Ian T. Lawson,Edward T. A. Mitchard,Susan Page,Yannick Enock Bocko,Suspense Averti Ifo +8 more
TL;DR: Radiocarbon dates indicate that peat began accumulating from about 10,600 years ago, coincident with the onset of more humid conditions in central Africa at the beginning of the Holocene, making the Cuvette Centrale depression in the central Congo Basin the most extensive peatland complex in the tropics.

Rainfall regimes of the Green Sahara.
TL;DR: Evidence for a prolonged “pause” in Green Sahara conditions 8000 years ago is found, coincident with a temporary abandonment of occupational sites by Neolithic humans and climate models systematically fail to reproduce the Green Sahara.

Exceeding 1.5°C global warming could trigger multiple climate tipping points
David I. Armstrong McKay,Arie Staal,Jesse Abrams,Ricarda Winkelmann,Boris Sakschewski,Sina Loriani,Ingo Fetzer,Sarah Cornell,Johan Rockström,Timothy M. Lenton +9 more
TL;DR: This paper provided a revised shortlist of global core and regional impact tipping points and their temperature thresholds, including the tipping point thresholds, time scales, and impacts of climate change, and provided an updated assessment of the most important climate tipping elements and their potential tipping points.

Palaeoclimatic insights into forcing and response of monsoon rainfall
TL;DR: Palaeoclimatic evidence of monsoon rainfall dynamics across different regions and timescales could help to understand and predict the sensitivity and response of monsoons to various forcing mechanisms.

TL;DR: In this article, the authors compile archaeological and palaeoenvironmental data from East Africa to document land-cover change, and environmental, subsistence and land-use transitions over the past 6000 years.

Climate Change 2001: Impacts, Adaptation, and Vulnerability
TL;DR: In this paper, the authors set the stage for impact, adaptation, and vulnerability assessment of climate change in the context of sustainable development and equity, and developed and applied scenarios in Climate Change Impact, Adaptation, and Vulnerability Assessment.
Book
Climate change 2007 : impacts, adaptation and vulnerability
TL;DR: In this paper, the authors present a cross-chapter case study on climate change and sustainability in natural and managed systems and assess key vulnerabilities and the risk from climate change, and assess adaptation practices, options, constraints and capacity.

A long-term numerical solution for the insolation quantities of the Earth
Jacques Laskar,Philippe Robutel,F. Joutel,Mickael Gastineau,Alexandre C. M. Correia,Alexandre C. M. Correia,Benjamin Levrard +6 more
TL;DR: In this article, a new solution for the astronomical computation of the insolation quantities on Earth spanning from −250 m to 250 m was presented, where the most regular components of the orbital solution could still be used over a much longer time span, which is why they provided here the solution over 250 m.

Flexible paleoclimate age-depth models using an autoregressive gamma process
TL;DR: Christen et al. as discussed by the authors used a gamma-to-regressive semiparametric model with an arbitrary number of subdivisions along the sediment to estimate the age of sediment cores.
