Short summary
In this study, we develop the first tree-ring-based precipitation reconstruction for the northern South American Altiplano back to 1625 CE. We established that the occurrence rate of extreme dry events together with a shift in mean dry conditions for the late 20th–beginning of the 21st century is unprecedented in the past 389 years, consistent with other paleoclimatic records. Our reconstruction provides valuable information about El Niño–Southern Oscillation influences on local precipitation.
