Integrated Waste Management As A Climate Change Stabilization Wedge For The Maletese Islands, Clyde Falzon
Integrated Waste Management As A Climate Change Stabilization Wedge For The Maletese Islands, Clyde Falzon
Masters Theses, 2010-2019
Planet Earth is finding difficulty in dealing with the continuous increase in anthropogenic greenhouse gas emissions. This is leading to change in climate which leads to extensive damage to communities, ecosystems and resources. This study is focussed on the waste sector which is the second largest greenhouse gas emitter in the Maltese islands after the energy (including transport) sector. Moreover, if practiced according to standards, waste management can lead to emission reduction. This work is based on the stabilisation wedges strategy and specifically focused on the integrated waste management wedge. Moreover in this work a life cycle assessment methodology is …
Changing Climatic Conditions In The Colorado River Basin: Implications For Water Resources Management In The Las Vegas Valley, Srijana Dawadi
Changing Climatic Conditions In The Colorado River Basin: Implications For Water Resources Management In The Las Vegas Valley, Srijana Dawadi
UNLV Theses, Dissertations, Professional Papers, and Capstones
Climate change affects the water available in a region. It also affects the water demand, because of the increase in temperature. A system dynamics model was developed for the Colorado River Basin (CRB), operating at a monthly time scale, to assess the potential impacts of climate change on streamflow in the Colorado River and its subsequent impact on the water resources management in the Las Vegas Valley (LVV). The effect of climate change on streamflow was evaluated using 16 global climate model outputs for 3 emission scenarios, also referenced in the Inter-Governmental Panel on Climate Change Fourth Assessment Report. Risk …
Bryoecology In The American Southwest: Patterns Of Biodiversity And Responses To Global Change, John Carroll Brinda
Bryoecology In The American Southwest: Patterns Of Biodiversity And Responses To Global Change, John Carroll Brinda
UNLV Theses, Dissertations, Professional Papers, and Capstones
This dissertation combines investigation of the large-scale responses of bryophyte species diversity and distribution with small-scale physiological adaptations to global change. These two areas of inquiry are linked because one way to predict plant species responses to global change is to examine their distribution across current ecological gradients produced by factors such as latitude and elevation. By examining these biogeographic patterns one can identify those species that have a narrow tolerance and therefore are most sensitive to change. Selected bryophytes might then be used as indicator species in long-term monitoring programs. Where historical data exist, these can be used to …
Uncertainty Estimation Of Extreme Precipitations Under Climate Change: A Non-Parametric Approach, Tarana A. Solaiman
Uncertainty Estimation Of Extreme Precipitations Under Climate Change: A Non-Parametric Approach, Tarana A. Solaiman
Electronic Thesis and Dissertation Repository
Assessment of climate change impacts on hydrology at watershed scale incorporates (a) downscaling of global scale climatic variables into local scale hydrologic variables and (b) assessment of future hydrologic extremes. Atmosphere-Ocean Global Climate Models (AOGCM) are designed to simulate time series of future climate responses accounting for human induced green house gas emissions. The present study addresses the following limitations of climate change impact research: (i) limited availability of observed historical information; (ii) limited research on the detection of changes in hydrologic extremes; and (iii) coarse spatio-temporal resolution of AOGCMs for use at regional or local scale. Downscaled output from …
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 …
Public Awareness About Global Warming In Hyderabad, India, Vani Sarraju Rao
Public Awareness About Global Warming In Hyderabad, India, Vani Sarraju Rao
Master's Theses
This study addressed public perceptions and awareness about global warming in India through a survey of 851 subjects in the city of Hyderabad in the year 2007. A stratified sample of nine segments of society showed that, although people consider global warming a serious problem, they do not clearly understand its causes, impacts, and solutions. The data analyses using paired T-tests indicated differences in levels of awareness about global warming, across age and education. ANOVA and regression analysis suggested that levels of awareness among respondents varied according to their occupation. The degree of seriousness with which subjects viewed global warming …
