Description
The authors analyzed Holocene pollen profiles derived from sediment cores retrieved from Lake Zempoala (19°03'N, 99°18'W) and nearby Lake Quila (19°04'N, 99°19'W) in the central Mexican highlands about 65 km southwest of Mexico City. This work revealed that the period AD 700-900 was the "driest and represents an extreme since the mid-Holocene." In addition, the researchers note that climatic conditions near the end of this 200-year period (~AD 900) were similar to those of today, in particular as recorded in data from Lake Zempoala.
