TL;DR: The authors applied compound-specific hydrogen isotopes (δD) and the TEX86 (tetraether index of 86 carbon atoms) temperature proxy to sediment cores from Lake Tanganyika to independently reconstruct precipitation and temperature variations during the past 60,000 years.

TL;DR: It is shown that on timescales beyond the decadal, the Indian Ocean drives East African rainfall variability by altering the local Walker circulation, whereas the influence of the Pacific Ocean is minimal.

TL;DR: In this article, the authors investigated the distribution of branched glycerol dialkyl glyceroline tetraethers (GDGTs) in recently deposited sediments from 46 lakes in tropical East Africa.

TL;DR: In this article, the MBT/CBT proxy was applied to lake sediments to investigate the origin and characteristics of these compounds in lacustrine environments, finding significant differences in the degree of methylation and cyclization between the soil samples and the aquatic samples, suggesting that there may be in situ production of GDGTs in the aquatic environment.

TL;DR: A community-sourced database of temperature-sensitive proxy records from the PAGES2k initiative, suited to investigations of global and regional temperature variability over the Common Era, and is shared in the Linked Paleo Data (LiPD) format, including serializations in Matlab, R and Python.
