Macro-scale space systems for geoengineering
… to reduce these pressures, namely space-based geoengineering to offset the effect of a warming climate and the use of orbiting reflectors to reduce the challenges of human exploration of the Moon. Several dust cloud based geoengineering methods are investigated, with the aim of improving on the …

Mirror, mirror : fairness and justice in climate geoengineering
Climate geoengineering seems an increasingly likely prospect as the gap between current mitigation action and that needed to avoid dangerous climate change remains substantial. Climate change raises fundamental questions of justice with respect to future generations, the poor and vulnerable in the …

Cellulose nanocrystals as a candidate for solar geoengineering
Geoengineering refers to deliberate and large scale interventions in the Earth’s climate, in this case, in pursuit of global warming mitigation. Stratospheric aerosol injection (SAI) and marine cloud brightening (MCB) are two methods of geoengineering that both aim to achieve solar radiation …

Essays on the Economics of Climate Change and Geoengineering
… on macroeconomic outcomes and the role of solar geoengineering in reducing these impacts. Solar geoengineering is different from traditional mitigation in at least three ways; it is inexpensive, quick, and imperfect. These characteristics place the technology as an imperfect but arguably …

‘Opening up’ geoengineering appraisal: Deliberative Mapping of options for tackling climate change
… climate system, known collectively as climate ‘geoengineering’, have been proposed in order to moderate anthropogenic climate change. A host of normative rationales for geoengineering has led to a growing number of appraisals to evaluate the different proposals and provide decision support. This …

Potential impact of stratospheric aerosol geoengineering on projected temperature and precipitation extremes in South Africa
Climate geoengineering technologies are being increasingly investigated by Earth system science researchers to mitigate climate change. Stratospheric Aerosol Injection (SAI) is one such option that is popularly debated as a potential measure to offset anthropogenic warming, while signatories of the …

Rethinking Environment: The Ethics of a Constructionist View of Our Relation to Nature
… In Chapter 4 I turn to climate change and geoengineering, arguing that a class of objection to geoengineering cannot be sustained in light of the theory of the constructed niche. In Chapter 5 I argue that the constructionist theory provides reason to recognize moral obligations to …

Micromechanics of Granular Media: A Fundamental Study of Interphase Systems
… significant and original contributions to the geoengineering, material science, geophysics and granular physics literature.

World Court
… crimes pertaining to uncoordinated attempts at geoengineering, the development of harmful synthetic biology and nanotechnology, would not only implicate Western and developed, but also corporations, special interest groups and individuals. The thesis is literally cited in the contemporary …

Application and Evaluation of Non-Destructive Testing Methods for Buried Pipes
… of 1.35 m) was prepared in the West Pit of the Geoengineering Laboratory at Queen’s University, featuring prefabricated erosion voids of known dimensions adjacent to the pipes. Tests were conducted using handheld and conventional Backscatter Computed Tomography (BCT), Pipe Penetrating Radar …

Our Ice Age: The Geohistorical Imagination in the Northern Hemisphere
… practices of “rewilding” and geoengineering, the park represents an ambiguous response to the conditions of the Anthropocene. Theorizing the “geohistorical imagination” that threads through these texts, this research shows how representations of the ice age perpetually shape …

On the role of natural laboratories and natural experiments in elucidating cloud-aerosol-climate interactions: A story of ships, smoke, and shutdowns
Uncertainties in how airborne particles (aerosol) influence cloud reflectivity hinder our understanding of anthropogenic climate change. The study of aerosol-cloud interactions (ACI) is complicated by the difficulty of disentangling aerosol effects from other phenomena like meteorological …

CLIMATE AS ASSEMBLAGE: IMAGINING AN ECOLOGICAL METAPHYSIC
Human interventions have resulted in striking changes to the global climate. I work from the understanding of anthropogenic climate change as the product of 250 years of emissions brought about through industrialization and continued by our fossil fuel economies and lifestyles. The instrumentalism …

Dynamics and Control of Very High Altitude Tethered Balloons
This research involves the development of a full 3-dimensional nonlinear model of a tethered aerostat, with the aim of conducting a preliminary feasibility assessment of Very High Altitude Tethered Balloons (VHATBs) under both steady-state and extreme operational conditions. A discretized …

Engineering geological characterization of volcanic rocks of ethiopian and sardinian highlands to be used as construction materials
… the results of the study conducted on the “Geoengineering characterization of volcanic rocks from Ethiopian and Sardinian highlands to be used as construction materials”. Though, the two project areas are geographically far apart, both are partly covered with volcanic rocks mainly consisting …
