TL;DR: The Laguna Potrok Aike lake in southern Patagonia, Argentina, has been analyzed using a multi-proxy approach as discussed by the authors, which reveals an unprecedented continuous high-resolution climatic record for the steppe regions of southern Argentina and reveals that rapid climate changes before the turn of the first millennium were detected followed by medieval droughts which are intersected by moist and/or cold periods of varying durations and intensities.

TL;DR: A high-resolution multiproxy geochemical approach was applied to the sediments of Laguna Potrok Aike in an attempt to reconstruct moist and dry periods during the past 16 000 years in south- eastern Patagonia.

TL;DR: In this article, a stable isotope database (δ2H and δ18O) is presented for estimating evaporation to inflow ratios (E/I) of lakes in semi-arid southern Patagonia.

TL;DR: In this paper, high-resolution analyses of allochthonous pollen input into crater lake sediments of Laguna Potrok Aike in the semi-arid Patagonian steppe reflect the variability of zonal wind intensities during the Holocene at 52° southern latitude.

TL;DR: In this paper, the authors investigate whether regional differences in fire histories are related to climatic gradients in Fuego-Patagonia, South America, and conclude that fire-conducive climate conditions appear to have been a prerequisite for the spread of fires.
