Collapse of ancient Mayan capital linked to drought

UAlbany professor's research sheds light on link between climate change, societal instability Prolonged drought likely helped to fuel civil conflict and the eventual political collapse of Mayapan, the ancient capital city of the Maya on the Yucatán Peninsula, suggests a new study in Nature Communications that was published with the help of a University at Albany archeologist. Mayapan served as the capital to some 20,000 Maya people in the 13th through mid-15th centuries but collapsed and was abandoned after a rival political faction, the Xiu, massacred the powerful Cocom family. Extensive historical records date this collapse to sometime between 1441 and 1461. But new evidence shows drought in the century prior may have played a larger role in the city’s demise than was previousl...

New research published this week by University of New Mexico archaeologist Keith Prufer shows that a site in Belize was critical in studying the origins of the ancient Maya people and the spread of maize as a staple food. According to the paper South-to-north migration preceded the advent of intensive farming in the Maya region, published this week in Nature Communications and co-led by Prufer, excavations in Belize, along with ancient DNA analysis, indicate a previously unknown migration of people–carrying maize–from an area of South America northward to the Maya region. Scientists excavate findings at the Belize Rock Shelter Site. Prufer and his colleagues excavated 25 burials dating from 10,000 to 3,700 years ago from two cave or rock shelter sites located in the rem...

An international team of scientists including Rutgers researchers has found that modern rates of sea level rise began emerging in 1863 as the Industrial Age intensified, coinciding with evidence for early ocean warming and glacier melt. The study, which used a global database of sea-level records spanning the last 2,000 years, will help local and regional planners prepare for future sea-level rise. The study appears in the journal Nature Communications. Sea-level rise is an important indicator of broader climate changes. By identifying the time when modern rates of sea-level rise emerged above natural variability, the researchers were able to pinpoint the onset of a significant period of climate change. By examining the worldwide records, the researchers found that glob...
