Possible role of climate in the collapse of Classic Maya civilization
THE Maya civilization developed around 3,000 years ago in Mesoamerica, and after flourishing during the so-called Classic period, it collapsed around 750–900 AD1. It has been specula ted2–6 that
Solar Forcing of Drought Frequency in the Maya Lowlands
It is concluded that a significant component of century-scale variability in Yucatan droughts is explained by solar forcing, and some of the maxima in the 208-year drought cycle correspond with discontinuities in Maya cultural evolution, suggesting that the Maya were affected by these bicentennial oscillations in precipitation.
Reconstruction of Caribbean climate change over the past 10,500 years
SEDIMENT cores from low-latitude lakes provide some of the best records of tropical climate change since the late Pleistocene. Here we report a high-resolution reconstruction of Caribbean climate
Climate Variability on the Yucatan Peninsula (Mexico) during the Past 3500 Years, and Implications for Maya Cultural Evolution
Climate variability on the Yucatan Peninsula during the past 3500 yrs is reconstructed from the measurement of δ18O in monospecific ostracods and gastropods in a 6.3-m sediment core from Lake Punta
Climate change on the Yucatan Peninsula during the Little Ice Age
Climate Change as the Dominant Control on Glacial-Interglacial Variations in C3 and C4 Plant Abundance
Although C4 plant expansions have been recognized in the late Miocene, identification of the underlying causes is complicated by the uncertainties associated with estimates of ancient precipitation,
Climate Variation and the Rise and Fall of an Andean Civilization
Paleolimnological and archaeological records that span 3500 years from Lake Titicaca and the surrounding Bolivian–Peruvian altiplano demonstrate that the emergence of agriculture (ca. 1500 B.C.) and
Stable isotope (δ13C and δ15N) signatures of sedimented organic matter as indicators of historic lake trophic state
We explored the use of carbon and nitrogen isotopes (δ13C and δ15N) in sedimented organic matter (OM) as proxy indicators of trophic state change in Florida lakes. Stable isotope data from four
