Decreasing stream habitat for Greenback cutthroat trout under future climate projections in headwater streams of the southern Rocky Mountains, Colorado
… streams are especially vulnerable to changing climate, and coldwater fish are especially sensitive to the fluctuations in streamflow and water temperature during summertime low flows. Though previous studies have provided insights on how changes in climate and alterations in stream discharge …

Assessing the climatic suitability of Bambara groundnut as an underutilised crop to future climate projections in Sikasso and Ségou, Mali
This study evaluates how future climatic projections will affect the suitability of bambara groundnut (Vigna subterranean(L) Verdc.), a type of underutilised crop in Sikasso and Ségou, southern Mali. This study was performed using a simulation approach, which considered the potential changes in …

Simulation and assessment of highly altered hydrologic system responses to anthropogenic and natural stressors at the watershed scale
… made it possible to assess the impacts of future climate and land use changes over the watershed responses. Although, the conceptualization of the physical processes representing the WMPs is challenging, the ability to create feasible land use scenarios under future climate projections is a …

The impact of volcanic halogens, climate change, and sulfate aerosol geo-engineering on the atmospheric effects of volcanic eruptions
… how the co-emission of volcanic halogens, climate change, and concurrent sulfate aerosol geo-engineering would alter the atmospheric effects of sulfur-only explosive volcanic eruptions has, previously, been under-researched. In this thesis, aerosol-chemistry-climate model simulations are …

Resiliency Oriented Scenario Generation Framework for Natural Gas Infrastructure
… scale, with few possibilities for extension to future climate impacts. Our work contributes to a framework for scenario-based resilience quantification of regional power systems under power-NG interdependencies. Specifically, we develop a scenario generation approach to model disruptions in the …

Modeling the potential impacts of climate change on streamflow variability in the North Fork of Elk Creek Experimental Watershed, West-Central, Montana
This study hypothesizes the effects of global climate change on the hydrologic regime of West-Central Montana, focusing on the North Fork of Elk Creek, a 6.6 km2 (2.6 mi²) Experimental Watershed. This is important to understand in snowmelt-dominated watersheds, as it is already well documented by …

Rainfall variability and change in South Africa (1976-2065)
… for life’s continuity. South Africa is prone to future climate uncertainties due to global climate change. The aim of this study is to investigate rainfall variability and change in South Africa on a present day (1976-2005), near-future (2006-2035) and far-future (2036-2065) climate. For the …

Characterization of the impacts of the physiological response of vegetation to increasing levels of atmospheric carbon dioxide
… likely does not significantly affect historical climate change assessments. However, the increase in magnitude and areal extent of the changes in climate accompanying higher levels of CO2 underlines the need for the physiological response to be included in future climate projections to avoid …

The Impact of a Warmer Climate on Atmospheric Circulation with Implications for the Asian Summer Monsoon
… in modern observations and projected under future climate change scenarios. These conditions were also present in the Warm Pliocene (3.3 - 3.0 million years ago), a paleoclimatic interval that bares resemblance to future global warming. This dissertation investigates the impact of both …

Assessing Natural Hazards and Climate Change in a Mountain Region with a Hydrological Digital Twin
… mountain regions, driven by increasing exposure, climate change-driven extremes, and improved impact reporting, highlight the need for a multi-hazard approach in their study. Multi-hazard risk assessment requires clear methodologies (hazard, exposure, vulnerability), yet high-resolution frameworks …

Evaluation of climate change impacts on the hydrologic response of a sparsely-monitored basin in Sardinia, Italy, through distributed hydrologic simulations and hydrometeorological downscaling
… Mediterranean basins are heavily influenced by climate variability. Modeling these watersheds is difficult due to the complex nature of the hydrologic response as well as the sparseness of hydrometeorological observations. In this work, we first present a strategy to calibrate a distributed …

A CMIP5 Model Selection Specific to South Africa's Winter Rainfall Zone
… of South Africa, seeking to reduce the range of future climate projections through identifying a subset of models with increased realism and independence. In order to navigate the subjectivity in identifying relevant circulation metrics to assess models against, the ‘Day Zero' drought is used as …

Benchmarks for the future: long-term vegetation change derived form palaeoecological techniques in West-Coast Renosterveld, South Africa
… fragments an irreplaceable conservation value. Future climate projections for the region suggest a general warming of 1.5-3.5 °C, a 30-50% decrease in precipitation, an increase in drought periods and shorter rainy seasons with important consequences for the vegetation of the CFR. There is …

THE VARIABILITY OF DROUGHT DYNAMICS IN THE SOUTHWEST UNITED STATES AND AN ANALYSIS OF DROUGHT RISK IN THE NORTHEASTERN UNITED STATES
… of Dr. Toby Ault as a member of the Emergent Climate Risk Lab. Herein, I used a variety of tools to analyze the variability of hydroclimate teleconnections of the southwest United States (SWUS) to El Niño Southern Oscillation (ENSO), which included observations, paleoclimate records, general …

Amphibian and reptile conservation in a changing environment: Case studies from the southeastern United States
… from an increasing human population and climate change, that is likely to impact all remaining natural areas to some degree. In this work, I examine some of the challenges currently facing imperiled species of reptiles and amphibians in this region. The work is focused on two species, the …

Using Machine Learning and the Water Evaluation and Planning model to Evaluate Climate Change Impacts on Surface Water Allocation in the Upper Awash Sub-Basin, Ethiopia
Climate change, rapid urbanisation, and population growth are placing escalating pressure on surface water resources in Ethiopia’s Upper Awash Sub-Basin, a region already grappling with rising agricultural demand and limited water availability. This study presents an integrated modelling framework …

Constraining uncertainty in climate sensitivity : an ensemble simulation approach based on glacial climate
Uncertainty about the sensitivity of the climate system to changes in the Earth’s radiative balance constitutes a primary source of uncertainty for climate projections. Given the continuous increase in atmospheric greenhouse gas concentrations, constraining the uncertainty range in such type of …

NARCCAP Model Assessment and Future Projections For the Southeast United States
<p>Global climate models (GCMs) provide most climate change projections, but their coarse resolution must be downscaled to more local scales in order to conduct meaningful climate impact assessments. This dissertation investigates dynamically downscaled regional climate model (RCM) output from the …

On the Energy Sustainability of Active and Passive Building Integrated Technologies in the Context of a Changing Climate for Tropical Coastal Cities
… where the two-way interaction between the urban climate and buildings is missing. Thus, the effect of energy mitigating technologies on the microclimate and energy demand on a scale of a city is still unknown, so is the assessment of their mitigating impacts under future climate conditions. Such …
