Federal carbon regulation : implications and adaptation strategies for local policymakers in Texas

Smeltzer, David Patrick 29 November 2012 (has links)
In the absence of federal climate change initiatives, Texas cities have been free to pursue their own local energy and environmental policy objectives. However, recent trends in federal climate change politics have made it clear that the era of federal inaction on climate change is nearing an end. This report argues that these trends will eventually culminate in a comprehensive regulatory structure with serious implications for the entire energy landscape of Texas. Texas cities that adapt quickly to these new conditions will experience greater success in the new low-carbon economy. Determining which adaptation strategy is appropriate for each city, however, is largely a function of the policy priorities of the city in question. This report identifies four, often conflicting, policy perspectives that influence the development of climate change policy priorities: Environmental Protection, Economic Stability, Peak Oil Production, and Energy Security. It then analyzes these perspectives in order to develop criteria for the proper selection of future energy and environmental policies. Finally, this report examines a variety of proposed policy initiatives to identify strategic options for each perspective and opportunities for mutual gain. / text

Contesting transdisciplinary climate knowledge: a decolonial perspective on the FRACTAL project in Windhoek, Namibia

Pelaez, Avila Julia Peláez 06 May 2020 (has links)
Recent trends in sustainability research have particularly propagated transdisciplinary approaches in knowledge production. These new modes of knowledge production seek to deconstruct universalist principles and epistemic authorities from positivist research approaches. The potential of replicating existing power dynamics into these transdisciplinary spaces has, however, not sufficiently been critically questioned yet. This study proposes that transformative change in development of African cities requires a deconstruction of these power dynamics, that current transdisciplinary sustainability research is not yet sufficiently engaging in. To examine the power dynamics, the study applied a decolonial lens in its analysis. In a novel approach to contesting climate knowledge, the study sought to deconstruct the foundational concepts that are operationalised in the transdisciplinary knowledge generation. The analysis focused on tracing assumptions to identify imaginaries, that construct the geopolitical space and condition knowledge politics within a transdisciplinary research programme in Windhoek, Namibia. It further sought to reveal the mechanisms in the programmatic research design that condition epistemic authorities and subjectivities in the collaborative processes. Power dynamics were traceable through imaginaries as well as the evidencing of epistemic authority. Two overarching imaginaries could be traced, which are based in the construction and engagement of the geopolitical space in Windhoek: the imaginary of the social impact and desirable future and the imaginary of the sciencepolicy interface. Both imaginaries were underpinned by the vision of transformation, whose operationalisation revealed to be instrumental in determining the actual transformational potential in contrast to the envisioned one. The analysis indicated the concept of transformation to be an inhibiting factor due to uncontested power dynamics that were replicated in the transdisciplinary space. Epistemic authority was especially evident in connection with the climate information that was generated to inform the knowledge co-production. A contestation of authoritative knowledge was evident with regards to contextualising the information for present and future climates in Windhoek. However, the scientific climate information itself was not questioned for its authority. The conceptual design of the stakeholder engagement revealed to be the main mechanism that created subjectivity. The study concluded with an exploratory section, an ‘epistemic disobedience’, which engages the principle of Walking With that is used by the indigenous activist movement of the Zapatistas in Mexico to create a vision of a new world. Walking With is used to reconstruct a vision of a decolonial approach to generating climate knowledge in an African urban space. This exploration further exemplifies a dimension of decolonial criticism, which is the importance of going beyond deconstruction towards fostering decolonial thinking.

Investigation of the Variability of Extreme Tornado Climatology

Farney, Tory 11 May 2013 (has links)
Previous tornado climatology research has relied primarily upon means of tornadoes or tornado days. Understanding the variability of tornado days however, will result in a more comprehensive understanding of the climatological distribution of tornadoes. In a changing environment, the extremities of a distribution should change faster than the mean of that distribution. Two methods of analyzing tornado days for predefined areas across the continental United States using the Storm Prediction Center's publication Storm Data from 1950 to 2011 are conducted in this study. Statistical analysis of averages, return periods, and percentiles reveals the variability in the record while consecutive tornado days present an alternative way to assess the seasonal repeatability and to assess risk for historic, multi-day tornado outbreaks. The results of this research will help to better define the traditional “tornado alley” as well as highlight other high-risk locations, especially those with higher interannual variability.

Response of Alpine Treeline Ecotones to 20th Century Climate Change: A Comparative Analysis from Kananaskis, Alberta

Brown, Robert 18 January 2013 (has links)
This study examines the changing conditions at high elevation alpine treeline ecotones (ATEs) in the southern Rocky Mountains of Alberta, Canada. Using age reconstructions from core and disc samples removed from trees at ATEs throughout the Kananaskis Valley of Alberta, we were able to identify statistically significant correlations between warming winter temperatures and seedling establishment at elevations beyond the present treeline. Further, we were able to identify multi-phase patterns of upslope treeline encroachment, suggesting climate as a key driver of initial seedling establishment beyond modern treeline elevations succeeded by a secondary process of forest density infilling largely controlled by the availability of local viable seed sources and the alterations of local microclimates that promote heightened seedling establishment. The results suggest that ongoing anthropogenic climate warming will continue to drive the upslope encroachment of ATEs in Kananaskis Country, Alberta.
