In the past two decades, much has been learned about the late Quaternary climate history of the Atacama Desert with some details still unclear about the seasonality, timing and extent of wet and dry phases. Modern climate studies reveal that, far from exhibiting a unique pattern, seasonal precipitation originates from many sources and mechanisms. For the last 16 ka, we attempt to sort out these complexities...
Chemical composition, magnetic susceptibility and texture of sediments in a swamp from the Los Petenes Biosphere Reserve provide information about late Holocene hydrological variations on the western margin of the Yucatan Peninsula, Mexico. Periods of lower than average amounts of K‐bearing clastics during 2580–2050, 1100–825 and 700–160 cal a BP represent drought intervals. Magnetic minerals were...
