Title Impacts of Climate Change on the Collapse of Lowland Maya Civilization Type Journal Article
Year 2016 Publication Annual Review of Earth and Planetary Sciences Abbreviated Journal Annu. Rev. Earth Planet. Sci.
Volume 44 Issue 1 Pages 613-645
Keywords Holocene climate change; societal collapse; paleoclimatology; archaeology; Mesoamerica
Abstract Paleoclimatologists have discovered abundant evidence that droughts coincided with collapse of the Lowland Classic Maya civilization, and some argue that climate change contributed to societal disintegration. Many archaeologists, however, maintain that drought cannot explain the timing or complex nature of societal changes at the end of the Classic Period, between the eighth and eleventh centuries CE. This review presents a compilation of climate proxy data indicating that droughts in the ninth to eleventh century were the most severe and frequent in Maya prehistory. Comparison with recent archaeological evidence, however, indicates an earlier beginning for complex economic and political processes that led to the disintegration of states in the southern region of the Maya lowlands that precedes major droughts. Nonetheless, drought clearly contributed to the unusual severity of the Classic Maya collapse, and helped to inhibit the type of recovery seen in earlier periods of Maya prehistory. In the drier northern Maya Lowlands, a later political collapse at ca. 1000 CE appears to be related to ongoing extreme drought. Future interdisciplinary research should use more refined climatological and archaeological data to examine the relationship between climate and social processes throughout the entirety of Maya prehistory.

Title Climate Change and Tourism in English-Language Newspaper Publications Type Journal Article
Year 2020 Publication Journal of Travel Research Abbreviated Journal Journal of Travel Research
Volume 59 Issue 2 Pages 352-366
Keywords Holocene climate change; tourism; machine learning; content analysis; mass media; big data
Abstract Tourism is one of the sectors of the economy that is most dependent on climate, creating multiple vulnerabilities and new opportunities arising with changing climate. Even though the links between tourism and climate have been well researched, this scientific knowledge has not percolated into policies and the ability to act. This disconnect between scientific knowledge and practices is frequently blamed on inadequate climate change communication to the public in mass media. We studied the mass media framing of climate change and tourism by analyzing English newspaper publications worldwide over the past 30 years. The paper presents a Big Data analysis of the content, geographical patterns, and temporal changes in newspapers' publications on climate change and tourism.

Title Abrupt climate variability since the last deglaciation based on a high-resolution, multi-proxy peat record from NW Iran: The hand that rocked the Cradle of Civilization? Type Journal Article
Year 2015 Publication Quaternary Science Reviews Abbreviated Journal Quaternary Science Reviews
Volume 123 Issue Pages 215-230
Keywords Holocene climate; Compound-specific biomarker; Cradle of Civilization; Atmospheric dust; Ombrotrophic peat; Younger Dryas; Iran
Abstract We present a high-resolution (sub-decadal to centennial), multi-proxy reconstruction of aeolian input and changes in palaeohydrological conditions based on a 13000 Yr record from Neor Lake's peripheral peat in NW Iran. Variations in relative abundances of refractory (Al, Zr, Ti, and Si), redox sensitive (Fe) and mobile (K and Rb) elements, total organic carbon (TOC), δ13CTOC, compound-specific leaf wax hydrogen isotopes (δD), carbon accumulation rates and dust fluxes presented here fill a large gap in the existing terrestrial paleoclimate records from the interior of West Asia. Our results suggest that a transition occurred from dry and dusty conditions during the Younger Dryas (YD) to a relatively wetter period with higher carbon accumulation rates and low aeolian input during the early Holocene (90006000 Yr BP). This period was followed by relatively drier and dustier conditions during middle to late Holocene, which is consistent with orbital changes in insolation that affected much of the northern hemisphere. Numerous episodes of high aeolian input spanning a few decades to millennia are prevalent during the middle to late Holocene. Wavelet analysis of variations in Ti abundances as a proxy for aeolian input revealed notable periodicities at 230, 320, and 470 years with significant periodicities centered around 820, 1550, and 3110 years over the last 13000 years. Comparison with palaeoclimate archives from West Asia, the North Atlantic and African lakes point to a teleconnection between North Atlantic climate and the interior of West Asia during the last glacial termination and the Holocene epoch. We further assess the potential role of abrupt climate change on early human societies by comparing our record of palaeoclimate variability with historical, geological and archaeological archives from this region. The terrestrial record from this study confirms previous evidence from marine sediments of the Arabian Sea that suggested climate change influenced the termination of the Akkadian empire. In addition, nearly all observed episodes of enhanced dust deposition during the middle to late Holocene coincided with times of drought, famine, and power transitions across the Iranian Plateau, Mesopotamia and the eastern Mediterranean region. These findings indicate that while socio-economic factors are traditionally considered to shape ancient human societies in this region, the influence of abrupt climate change should not be underestimated.
