Wildfire Risk In Mountain West States, 2017-2021, Olivia K. Cheche, Corryn Richardson, Zachary Billot, Miguel Soriano Ralston, Vanessa Booth, Caitlin J. Saladino, William E. Brown Jr.
Wildfire Risk In Mountain West States, 2017-2021, Olivia K. Cheche, Corryn Richardson, Zachary Billot, Miguel Soriano Ralston, Vanessa Booth, Caitlin J. Saladino, William E. Brown Jr.
Environment
This fact sheet examines data on wildfire destruction in the Mountain West states of Arizona, Colorado, Nevada, New Mexico, and Utah. The original report from the Insurance Information Institute presents findings on percent of properties at risk of wildfire destruction, the number of wildfires by state, and numbers of acres burned per state.
Changes In Snow Phenology From 1979 To 2016 Over The Tianshan Mountains, Central Asia, Tao Yang, Qian Li, Sajjad Ahmad, Hongfei Zhou, Lanhai Li
Changes In Snow Phenology From 1979 To 2016 Over The Tianshan Mountains, Central Asia, Tao Yang, Qian Li, Sajjad Ahmad, Hongfei Zhou, Lanhai Li
Civil and Environmental Engineering and Construction Faculty Research
Snowmelt from the Tianshan Mountains (TS) is a major contributor to the water resources of the Central Asian region. Thus, changes in snow phenology over the TS have significant implications for regional water supplies and ecosystem services. However, the characteristics of changes in snow phenology and their influences on the climate are poorly understood throughout the entire TS due to the lack of in situ observations, limitations of optical remote sensing due to clouds, and decentralized political landscapes. Using passive microwave remote sensing snow data from 1979 to 2016 across the TS, this study investigates the spatiotemporal variations of snow …
Relationship Between Ocean-Atmospheric Climate Variables And Regional Streamflow Of The Conterminous United States, Swastik Bhandari, Ajay Kalra, Kazi Tamaddun, Sajjad Ahmad
Relationship Between Ocean-Atmospheric Climate Variables And Regional Streamflow Of The Conterminous United States, Swastik Bhandari, Ajay Kalra, Kazi Tamaddun, Sajjad Ahmad
Civil and Environmental Engineering and Construction Faculty Research
Understanding the interconnections between oceanic-atmospheric climate variables and regional streamflow of the conterminous United States may aid in improving regional long lead-time streamflow forecasting. The current research evaluates the time-lagged relationship between streamflow of six geographical regions defined from National Climate Assessment and sea surface temperature (SST), 500-mbar geopotential height (Z500), 500-mbar specific humidity (SH500), and 500-mbar east-west wind (U500) of the Pacific and the Atlantic Ocean using singular value decomposition (SVD). The spatio-temporal correlation between streamflow and SST was developed first from SVD and thus obtained correlation was later associated with Z500, SH500, and U500 separately to evaluate the …
Management Of An Urban Stormwater System Using Projected Future Scenarios Of Climate Models: A Watershed-Based Modeling Approach, Ranjeet Thakali, Ajay Kalra, Sajjad Ahmad, Kamal Qaiser
Management Of An Urban Stormwater System Using Projected Future Scenarios Of Climate Models: A Watershed-Based Modeling Approach, Ranjeet Thakali, Ajay Kalra, Sajjad Ahmad, Kamal Qaiser
Civil and Environmental Engineering and Construction Faculty Research
Anticipating a proper management needs for urban stormwater due to climate change is becoming a critical concern to water resources managers. In an effort to identify best management practices and understand the probable future climate scenarios, this study used high-resolution climate model data in conjunction with advanced statistical methods and computer simulation. Climate model data from the North American Regional Climate Change Assessment Program (NARCCAP) were used to calculate the design storm depths for the Gowan Watershed of Las Vegas Valley, Nevada. The Storm Water Management Model (SWMM), developed by the Environmental Protection Agency (EPA), was used for hydrological modeling. …
Integrating System Dynamics And Remote Sensing To Estimate Future Water Usage And Average Surface Runoff In Lagos, Nigeria, Gilles A. Kandissounon, Ajay Karla, Sajjad Ahmad
Integrating System Dynamics And Remote Sensing To Estimate Future Water Usage And Average Surface Runoff In Lagos, Nigeria, Gilles A. Kandissounon, Ajay Karla, Sajjad Ahmad
Civil and Environmental Engineering and Construction Faculty Research
The goal of this study was twofold; first analyze the patterns of water consumption in Lagos, Nigeria and use them in a System Dynamics (SD) model to make projections about future demand. The second part used remote sensing to quantify the contribution of extensive land use/cover change to urban flooding. Land use/cover dynamics over the past decade was analyzed using satellite imagery provided by Landsat Thematic Mapping (TM). Unsupervised classification was performed with false color composite using the Iterative Self-Organizing Data Analysis (ISODATA) technique in a Geographic Information Systems (GIS). The study area was divided into four different land use …
Climate Change And Eutrophication: A Short Review, Mohammad Nazari-Sharabian, Sajjad Ahmad, Moses Karakouzian
Climate Change And Eutrophication: A Short Review, Mohammad Nazari-Sharabian, Sajjad Ahmad, Moses Karakouzian
Civil and Environmental Engineering and Construction Faculty Research
Water resources are vital not only for human beings but essentially all ecosystems. Human health is at risk if clean drinking water becomes contaminated. Water is also essential for agriculture, manufacturing, energy production and other diverse uses. Therefore, a changing climate and its potential effects put more pressure on water resources. Climate change may cause increased water demand as a result of rising temperatures and evaporation while decreasing water availability. On the other hand, extreme events as a result of climate change can increase surface runoff and flooding, deteriorating water quality as well. One effect is water eutrophication, which occurs …
Religion, Partisanship, And Attitudes Toward Science Policy, Ted G. Jelen, Linda A. Lockett
Religion, Partisanship, And Attitudes Toward Science Policy, Ted G. Jelen, Linda A. Lockett
Political Science Faculty Research
We examine issues involving science which have been contested in recent public debate. These “contested science” issues include human evolution, stem-cell research, and climate change. We find that few respondents evince consistently skeptical attitudes toward science issues, and that religious variables are generally strong predictors of attitudes toward individual issues. Furthermore, and contrary to analyses of elite discourse, partisan identification is not generally predictive of attitudes toward contested scientific issues.
Climate Change And Real Estate: How Environmental Risks And Policies Impact Markets, Adele C. Morris
Climate Change And Real Estate: How Environmental Risks And Policies Impact Markets, Adele C. Morris
Brookings Scholar Lecture Series
Climate change could worsen environmental conditions that affect real estate values, such as extreme weather events and coastal erosion. But policies to prevent climate change can also affect real estate values, for example through higher energy prices and land use regulation. This lecture will examine the linkages between the climate change risks, climate policy, and real estate markets. We will also discuss the likely regional economic effects of recent proposed climate legislation.

Brookings Scholar Lecture Series
Since 1979, 20% of the polar ice cap has melted away. While the public is aware of climate change, the urgency to action is not there. Climate change is also an issue of national security, but enforcement of the the Kyoto and Copenhagen treaties is hampered.

Uncertainty, Climate Change And Nuclear Power, David M. Hassenzahl
Uncertainty, Climate Change And Nuclear Power, David M. Hassenzahl
Public Policy and Leadership Faculty Publications
Long time-horizon environmental risks with potential for global impacts have increased in visibility over the past several decades. Such issues as climate change, the nuclear fuel cycle, persistent synthetic chemicals, and stratospheric ozone depletion share some characteristics, including intergenerational impacts, strongly decoupled incidence of risks and benefits, substantial decision stakes and extreme uncertainty. What is not well understood are the similarities and differences among sources and implications of uncertainty among these global environmental threats, especially those associate with current and future human behavior. This describes the uncertainties associated with managing two global concerns: the nuclear (fission) fuel cycle and anthropogenic …
