Short summary
The study analyzed temperature-sensitive bacterial membrane lipids in Holocene Lake sediments from southwestern Greenland. Temperature maxima in five lakes occurred between 7000–5000 years ago, at a coastal site between 5000–3000 years ago, and at an inland site, far from the coast and the Greenland Ice Sheet, between 9000–7000 years ago. Local temperature variations, influenced by the ice sheet and ocean, likely caused discrepancies in the temperature time series.

The climatic factors sustaining vegetation in the Sahara during the African humid period (AHP) are still not fully understood. Using biomarkers in a marine sediment core from the eastern Mediterranean, we infer variations in Mediterranean (winter) and monsoonal (summer) rainfall in the Nile river watershed around the AHP. We find that winter and summer rain enhanced during the AHP, suggesting that Mediterranean moisture supported the monsoon in sustaining the “green Sahara”.

Western North American contains accessible and under-recognized paleolake records that hold the keys to understanding the drivers of wetter conditions in Pliocene Epoch subtropical drylands worldwide. In a 2021 ICDP workshop, we chose five paleolake basins to study that span 7° of latitude in a unique array able to capture a detailed record of hydroclimate during the Early Pliocene warm period and subsequent Pleistocene cooling. We propose new drill cores for three of these basins.

A better understanding of past climate variations is essential to apprehend future climatic changes. The aim of this study is to investigate the applicability of specific organic compounds of bacterial origin, 3-hydroxy fatty acids (3-OH FAs), as temperature and pH proxies at the global level using an extended soil dataset. We show the major potential of 3-OH FAs as such proxies in terrestrial environments through the different models presented and their application for palaeoreconstruction.

Short summary
Archaeal molecular fossils (tetraethers) have been used around the globe to track changes in climate. Little is known about the archaeal response to environmental change in soda lakes, especially lakes influenced by hydrothermal inputs. For the first time in Lake Magadi, we show tetraethers tracking abrupt changes in methane and non-methane producers due to hydrothermal inputs to the lake. This study provides insight into the role of hydrothermal water and methane production in soda lakes.
