Abstract:
... Scholars continue to debate the relative magnitude of pre- and post-Conquest anthropogenic landscape transformation in many regions of Mesoamerica. These debates have important implications for our understanding of the role of anthropogenic practices in the development, or at times degradation, of regional environments. Paleoecological records that provide long-term perspectives on climate change ...

climate; climate change; climate models; data collection; drought; lakes; lowlands; paleoclimatology; researchers; sediments; Central America; Mexico
Abstract:
... A growing body of paleoclimate data indicates that periods of severe drought affected the Maya Lowlands of southeastern Mexico and northern Central America, especially during the Terminal Classic period (ca. 800–950 CE), raising the possibility that climate change contributed to the widespread collapse of many Maya polities at that time. A broad range of paleoclimate proxy methods have been applie ...

Abstract:
... Chichén Itzá dominated the political landscape of the northern Yucatán during the Terminal Classic Period (AD 800–1000). Chronological details of the rise and fall of this important polity are obscure because of the limited corpus of dated hieroglyphic records and by a restricted set of radiocarbon dates for the site. Here we compile and review these data and evaluate them within the context of po ...

Abstract:
... Although fire was arguably the primary tool used by the Maya to alter the landscape and extract resources, little attention has been paid to biomass burning in paleoenvironmental reconstructions from the Maya lowlands. Here we report two new well-dated, high-resolution records of biomass burning based on analysis of macroscopic fossil charcoal recovered from lacustrine sediment cores. The records ...

Abstract:
... Polar ice sheets are remarkable repositories of tephra layers. The Talos Dome ice core (72°49′S, 159°11′E), drilled at the edge of the East Antarctic Plateau, close to Late Quaternary volcanoes, offers considerable potential to extend the current tephra time-stratigraphic framework. A tephrochronological study was undertaken of the ice core sections related to the Last Interglacial and the transit ...

Biological carbon sequestration through implementation of biomass plantations is currently being discussed as an option for climate engineering (CE) should mitigation efforts fail to substantially reduce greenhouse gas emissions. As it is a plant-based CE option that extracts CO2 from the atmosphere, it might be considered a ‘green’ CE method that moves the biosphere closer to its natural, i.e. pr ...
