Trace Element Variations In A Stalagmite From Southwest Mexico: Implications For Paleoclimate, Chad Michael Crotty

The combination of stable isotope and trace element concentrations in speleothems has been shown to be a valuable indicator for interpreting paleoclimatic conditions. Anomalous spikes in trace element concentrations have also been shown to indicate anthropogenic environmental changes to the surface, such as deforestation events. In this study, trace element concentrations (24Mg, 25Mg, 84Sr, 88Sr, 137Ba, and 238U) of a stalagmite (JX-6) from Juxtlahuaca Cave, in southwestern Mexico, were measured using an inductively coupled plasma mass spectrometer (ICP-MS). These trace element concentrations were compared to previously analyzed δ18O and δ13C values from JX-6, and to the results of previous studies …

Burdens And Benefits Of Climate Change Solutions: A Case Study Of Climate Change Skeptics And Deniers In Rural Nevada, Patricia Dutcher
UNLV Theses, Dissertations, Professional Papers, and Capstones
This dissertation is an ethnographic case study of climate change Doubtfuls and Dismissives with the purpose of understanding their perceptions of water use and renewable energy in the context of a changing climate. I also investigate the information sources and messages they use to understand climate change and climate change solutions. The Global Warming's Six Americas project identifies climate change Doubtfuls and Dismissives as one third of the American public, and an active voice in US climate change policy (Maibach et al, 2009; Leiserowitz et al., 2014). Doubtfuls are people with skeptical attitudes towards anthropogenic climate change, while Dismissives deny …
Climate Change, Disasters & Displacement, Elizabeth Ferris
Climate Change, Disasters & Displacement, Elizabeth Ferris
Brookings Scholar Lecture Series
This lecture examines trends in natural disasters, the effects of climate change, and their impact on human rights, including economic costs, the displacement/migration of people, and the likelihood that the poor and marginalized are most likely to be affected by natural disasters and climate change.
