Our paper in Quaternary International just went online today. The pithy takeaway: Ancient dryland farmers in Utah adapted to warming and drying during the MCA but were unable to adapt to increased variability at the MCA-LIA transition, and abandoned the area for maize farming. Because increased variability is one of the near certainties for temperate semi-arid

The North American Monsoon (NAM) is a major delivery system of water to the interior of the American Southwest, the Sonoran Desert in particular. The NAM usually peaks in the mid to late summer, arising from the south over the Sonoran desert (Adams and Comrie 1997; Higgins et al. 1997; Metcalfe et al. 2015). But the

The American Southwest has experienced a series of severe droughts interspersed with strong wet episodes over the past decades, prompting questions about future climate patterns and potential intensification of weather disruptions under warming conditions. Here we show that interannual hydroclimatic variability in this region has displayed a significant level of non-stationarity over the past millennium.
