Excited to share our new publication in QSR: The Altiplano paleoclimate of the last 21K, simulated by the CHELSA-TraCE21k transient downscaling.
Hope it can be a contribution to the climate history of this part of South America!

Lithium enrichment in the Qarhan Salt Lake (China) was a long-term process driven by interglacial-glacial cycles - Communications Earth & Environment
Glacial-interglacial cycles drove lithium-rich brine formation in the Qarhan Salt Lake in China, according to Th dating and fluid inclusion analyses in halite, and paleotemperature reconstructions.
