Impacts Of Climate Changes On The Spatiotemporal Distribution Of Precipitation In The Western United States, Peng Jiang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Precipitation in the Intermountain West is characterized by its great variability in both spatial and temporal distributions. Moreover, the spatiotemporal distribution of the precipitation is changing due to the climate changes. In this dissertation, three studies are conducted to investigate the multi-scale temporal variability of precipitation, the performance of current climate models on this variability, the influence of large-scale ocean oscillations on heavy precipitation, and the impact of human induced global warming on storm properties.

The first study is to examine the performance of current climate models on the simulation of the multi-scale temporal variability determined from the observed station …

Assessing Growth Response To Climate Controls In A Great Basin Artemisia Tridentata Plant Community, Lorenzo F. Apodaca

UNLV Theses, Dissertations, Professional Papers, and Capstones

An assessment of the growth response of key vegetative species to climatic variability is vital to identifying possible local impacts on ecosystems faced with imminent climate change. With current climate projections in Nevada predicting a shift to an even more arid climate with greater year-to-year variability, the imperative exists to identify the effects of specific climatic controls on plant growth and to research methods to assess large-scale vegetative changes, especially in more remote areas where readily available data sets may be lacking. This study utilized annual growth ring indices constructed from big sagebrush (Artemisia tridentatassp.tridentata) stems collected in Spring Valley, …

Could A State-Level Carbon Tax Work In The Intermountain West?, Adele C. Morris

Brookings Scholar Lecture Series

With the U.S. federal government stuck in partisan gridlock, attention increasingly turns to states and localities for innovative climate solutions. This talk will explore the option for Intermountain West states to tax carbon, including how they could establish a tax base, set price signals, and manage revenue. The presentation will pay special attention to the option of “swapping” a carbon tax for revenue sources that more negatively impact economic growth, such as taxes on business activity. This research will explore the advantages and disadvantages of different approaches and consider the issue of the burdens on lower income households and certain …

Soil Moisture Recognition And The Spatial Distribution Of Storm Activity In The Mojave Desert Using High-Resolution Aster And Modis Imagery For Thermophysical Mapping, Russell J. Skuse

UNLV Theses, Dissertations, Professional Papers, and Capstones

Climate models suggest that the Mojave Desert ecoregion is vulnerable to becoming drier in the future, and as the human population grows and development increases, environmental stresses will likely increase. Determining the spatial distribution and variation of soil moisture on a regional scale is an essential component to climate change, hydrologic, and habitat analyses. Soil permeability and sediment stability are characteristics that have been shown to be measurable from remote sensing observations. The primary objective of this project is to map the mechanical composition of the surface materials in the Mojave Desert ecoregion with implications for soil permeability, sediment stability, …

The Effects Of Climate Science Literacy And Cultural Polarization Around Climate Change Risk Perception, Gabriel R. Young, Helen R. Neill

Graduate Research Symposium (GCUA) (2010 - 2017)

Science communicators have struggled to provide meaningful information about climate change due to the complex nature of the problem and the polarized political and media landscapes, and yet, a well informed public is a crucial element to both public acceptance and policy initiatives aimed at climate change mitigation. Current literature suggests that scientific literacy actually increases cultural polarization around the issue of climate change (Kahan, 2012). This study adds to the literature by testing the hypothesis that climate change risk perception is more heavily tied to climate science literacy than general science literacy when controlling for cultural worldviews. We use …

Investigating Perspectives Of Rural Nevadans On Climate Change Solutions, Tricia Dutcher

Graduate Research Symposium (GCUA) (2010 - 2017)

Rural perspectives are important for the issue of climate change. Rural areas are high concentrations of active voters who deny the problem of anthropogenic climate change. Rural residents also face decisions about inviting large, utility scale renewable energy developments in their areas. This research examines rural Nevadan’s perspectives on climate change to offer insights about the relationship between climate change perceptions and communication strategies. The research offers policy implications that address context specific issues, solution-oriented dialogue, and interest matching to mitigate anthropogenic climate change.
