Quantifying The Carbon Stored And Sequestered By The Trees On Pomona College’S Campus, Paola A. Giron-Carson
Scripps Senior Theses
We are experiencing a climate crisis that must be confronted with strategic mitigation. Pomona College contributes to the climate crisis through its emissions for which there is a baseline record. However there is no baseline record of the climate mitigation currently performed by the trees on Pomona’s campus through carbon storage. This study seeks to determine a current baseline quantity of carbon stored and sequestrated by Pomona’s trees as well as possible courses of climate mitigation for Pomona College to take. Initial information gathering was conducted through interviews with several stakeholders. This study was conducted using data collected prior to …
Species Data And Vector Modeling: Evaluating Datasets For Improved Models Of Ixodes Ricinus Tick Distribution In Europe Under A Changing Climate, Steven Jones
Electronic Theses and Dissertations
To increase capacity for monitoring and surveillance of tick-borne diseases, publicly available tick distribution and climate change datasets are required to create accurate predictive distribution models. It is difficult, however, to assess model accuracy and utility when using incomplete datasets. The more recent development of comprehensive tick databases for Europe and availability of climate change scenarios from multiple IPCC Assessment Reports allows for improved modeling efforts. Multiple tick datasets were combined and three climate change projections were compared by predicting current and future distributions of Ixodes ricinus ticks in Europe using the MaxEnt species distribution model. Overall, much of Europe …
The Global Impact Of The Antarctic Ice Sheet In A Warming World: Using Numerical Modeling And Critical Physical Geography To Assess Climate Change, Sea Level Rise, And Climate Justice
Doctoral Dissertations
Anthropogenic climate change is causing disruptions in the Earth system with negative ramifications for life on our planet. Increasing atmospheric greenhouse gas concentrations lead to accumulated heat content and the cryosphere is one of the earliest places to show changes in response to rising temperatures. The melting of the Antarctic Ice Sheet will have myriad effects on global climate due to interconnections and feedbacks between the ice sheet, ocean, and atmosphere. In this dissertation I use numerical modeling and critical geography to assess future climate conditions that occur in response to changes in Antarctic Ice Sheet melt as well as …
Fire Emissions In The Tropical Indonesia: Improved Estimation And Driving Forces Investigation, Xiaoman Lu
Fire Emissions In The Tropical Indonesia: Improved Estimation And Driving Forces Investigation, Xiaoman Lu
Electronic Theses and Dissertations
Indonesia has experienced frequent fires since the 1970s due to large-scale peatland conversion and extensive drainage for agricultural development. Fire emissions released from these fires have led to Indonesia being the world’s 3rd largest emitter of greenhouse gases in certain years. Given that fire emissions severely affect climate, weather, and the human environment, numerous approaches have been developed to estimate fire emissions. However, existing emission estimates differ largely by a factor of four in this tropical country because of frequent cloud interferences and low-temperature smoldering fires. Therefore, this dissertation aims to improve the quantification of Indonesian fire emissions through enhanced …
Composite Analysis Of Mendenhall Glacier Interannual Glacial Health Decline, Hailey Marie Cantrell
Composite Analysis Of Mendenhall Glacier Interannual Glacial Health Decline, Hailey Marie Cantrell
Masters Theses
Glacial health in Alaska, USA is demonstrating an interannual declining trend. Repetitive years have suffered an imbalance between winter seasonal ice accumulation and summer seasonal ice loss. Increased ice loss has commonly been attributed to warmer Arctic summer temperatures, which contribute to greater calving events and amplified ablation. Study of the unique climatic influences by different variables is ongoing and at the forefront of climate-glacier interaction research.
This study is designed to quantitatively evaluate correlations between changes in Alaskan climatic patterns and an interannual trend of declining glacial health for Mendenhall Glacier by combining analysis of Landsat satellite imagery, teleconnection …
Ground Warming Leads To Changes In Carbon Cycling In Northern Fen Peatlands: Implications For Carbon Storage, Ericka James
Ground Warming Leads To Changes In Carbon Cycling In Northern Fen Peatlands: Implications For Carbon Storage, Ericka James
Electronic Thesis and Dissertation Repository
Northern peatlands store one third of the world’s soil carbon (C), as they remove more C from the atmosphere via photosynthesis than they release to the atmosphere through ecosystem respiration and methane (CH4) production. Climate change threatens this function by stimulating C release from peatland stores as peat temperatures warm and soil moisture is reduced. Ground heating of +4 °C above ambient peat temperatures was initiated in a Sphagnum moss-dominated, nutrient poor fen and a Carex sedge-dominated, intermediate nutrient fen. Over one growing season, Carex fen heated plots had increases in photosynthesis (+23%), ecosystem respiration (+22%), and CH …

Policy, Plans And Processes For Developing And Improving The Use Of Hazard Maps In Climate Change Adaptation For Yukon Communities, Stephanie Pike
Theses and Dissertations (Comprehensive)
Climate change has quickly become one of the most commonly discussed topics in northern Canada. Communities located in Canada’s north are facing impacts to every aspect of life. Hazard mapping is one of the tools used to predict risk from climate change impacts and thus assist communities in adaptation planning. The Northern Climate ExChange in Yukon has developed hazard maps for seven communities across Yukon. While hazard maps are a useful tool, in order for them to reach their maximum potential, users need to be well educated and trained to use them. Capacity and communication are arguably the most significant …

Environment And Human Health In The Anthropocene: Interaction Between Natural And Social Systems In Coastal Tanzania, Frederick A. Armah
Environment And Human Health In The Anthropocene: Interaction Between Natural And Social Systems In Coastal Tanzania, Frederick A. Armah
Electronic Thesis and Dissertation Repository
Coastal Tanzania, a region of historical and geopolitical importance in the western Indian Ocean, is a place where the problem of rapid environmental change is inextricably entwined with the challenges of development. In this region, although the fingerprint of the anthropocene has been discernible over the last century, there is paucity of research on how the population has interacted with the changing environment to generate disparities in perceptions of climate change and human health outcomes. The objectives of this thesis are four-fold: to assess barriers to climate change adaptation based on context (place), to explain group disparities in barriers to …

An integrated approach (remote sensing, geographical information systems [GIS], and modeling) was applied to conduct a number of hydrologic and environmental investigations in the Arabian Peninsula (AP) aimed at: (1) identifying the spatial and temporal climate change–related variations in precipitation over the AP using readily available, remotely acquired global precipitation data sets; (2) investigating the nature of the factors controlling the observed climatic variations; (3) estimating the partitioning of precipitation over the Red Sea Hills watersheds into runoff , recharge, and initial losses using calibrated continuous rainfall runoff models (Soil Water Assessment Tool [SWAT]); (4) identifying landslide (largely caused by …
The Periglacial Landscape Of Utopia Planitia; Geologic Evidence For Recent Climate Change On Mars., Mary C. Kerrigan
The Periglacial Landscape Of Utopia Planitia; Geologic Evidence For Recent Climate Change On Mars., Mary C. Kerrigan
Electronic Thesis and Dissertation Repository
The northern plains of Utopia Planitia, Mars, hosts an abundance of potential periglacial landforms including scalloped depressions, gullies, and polygon networks. This research was undertaken to investigate the distribution and stratigraphy of scalloped depressions in Utopia Planitia and to reconstruct the past environment in which this periglacial landscape formed. To that end, a revised geologic map of the region has been produced. We define, for the first time, a new Periglacial Unit, the youngest geologic unit in Utopia Planitia. We have also developed a model for the formation and evolution of the periglacial landscape examined by assessing the use of …

Response Of Inland Lakes To Climate Change Across The Tibetan Plateau Investigated Using Landsat And Icesat Data, Zewen Liu
Masters Theses
The Tibetan Plateau experienced tremendous climate change during the past four decades. Due to the large size, widely distribution of cryosphere, and diverse landforms, different parts of the plateau may experience different climate and cryosphere changing patterns. The changes of inland lakes within the plateau are important indicators of climate change as these lakes are fed by precipitation, permafrost degradation, and glacier melting that are all sensitive to climate change. To examine the spatial and temporal differences of lake variations across the Tibetan Plateau, Landsat images and ICESat/GLAS altimetry data were used to extract the changes in surface areas of …
Changes In The Hydrological Regime In The Upper Bow And Upper Athabasca Watersheds During The 20th Century, Heather A. Haines
Changes In The Hydrological Regime In The Upper Bow And Upper Athabasca Watersheds During The 20th Century, Heather A. Haines
Electronic Thesis and Dissertation Repository
This thesis examines 20th century regime changes for the headwaters of the Bow (1911-2005) and Athabasca (1971-2005) Rivers. Changes in precipitation and temperature associated with the Pacific Decadal Oscillation dominate the Bow streamflow record. Higher snowfall, lower mean temperatures, and greater annual discharges occur during the “cool” PDO phase (1947-1976) with lower snowfall, higher mean temperatures, and lower annual discharges during the “warm” (1925-1946, 1977-2005) phases. Any long-term linear trends in the Bow record are masked by these multidecadal trends. The Athabasca record is too short to compare to the PDO but available data show patterns similar to the …
Colorado's Large Snow Events' Impact On Tree Ring Growth And Dillon Reservoir, Katrina Leona Marzetta
Colorado's Large Snow Events' Impact On Tree Ring Growth And Dillon Reservoir, Katrina Leona Marzetta
Electronic Theses and Dissertations
Meteorological observations from 1894 through 2010 suggest that 17 historically large snow events occurred in the mountains of Colorado within Denver's water supply region. Of these 16 events, 14 can be identified in precipitation sensitive tree ring records as positive climatic pointer years. If these storms were to occur today, they would have the potential to fill reservoirs in Denver Water's supply system, even after years of sustained drought. These "drought busters" have the potential to refill Dillon Reservoir by increasing average yearly inflow up to 146% of the previous year's inflow. Such drought busters can help Denver recover from …

Climate Change And Human Health Consequences, Jennifer Alford
Climate Change And Human Health Consequences, Jennifer Alford
Social Sciences
The intent of this project is to highlight the human health ramifications of climate change and the strategies for coping with this challenge. Possible effects may include reduction in agricultural outputs, dwindling freshwater aquifers, intensification of tropospheric ozone, and expanding areas of disease-carrying vectors. Because humans are closely connected with their environment, we are directly affected by any environmental disturbance. Consequently, human health is vulnerable to the effects of climate change. The questions are: what are those consequences, how will we adapt, and what does the future hold?
