Global mean surface air temperature (GMST) change, due to increases in atmospheric carbon dioxide concentrations, is a fundamental measure of human induced climate change and its associated impacts. Estimates of the magnitude of GMST response to a doubling of atmospheric carbon dioxide (equilibrium climate sensitivity or ECS) remains uncertain over a broad range between 1.5-4.5K. Expected economic damages associated with climate change are strongly sensitive to this broad uncertainty, creating challenges in constructing mitigation policies to limit peak warming. In this thesis I explore uncertainty in the climate response through two methods. I show that potential constraints on the climate response using observations of a recent decade and planetary energy balance models are consistent with a low climate response that is not sampled by multi-model or perturbed physics ensembles of general circulation models (GCMs). I therefore subsequently set out to explore the physicality of the lower bound of climate response uncertainty in GCMs by conducting an emulator-driven perturbed physics ensemble search for low ECS models. I find a set of GCMs with ECS between 1.5K and 2K, driven primarily by negative feedbacks in tropical low cloud with GMST warming. Achieving low ECS is associated with reduced simulation fidelity relative to the standard version of the GCM, but fidelity reductions are judged to be insufficient to assuredly rule out an ECS between 1.5-2K in the real climate system. This experiment highlights the difficulty in further reducing climate response uncertainty in the near future. I therefore propose a new framing of mitigation policy that focuses on using physical methods to index the future evolution of policy variables to emergent climate change. Such a framing could lead to adaptive mitigation policies, aimed at limiting peak warming, that are demonstrably more robust under currently irreducible physical climate response uncertainty than conventional mitigation scenarios.

The current environmental crisis is due at least in part to a lack of effective science communication. Traditional methods of disseminating findings are important for continued progress but can be inaccessible to the public and rarely communicate the important emotional and cultural dimensions of environmental issues. Mitigation of the effects of climate change will not occur if a majority of people cannot understand the problem or do understand but fail to change their behaviors. There has been significant communications research into these issues—findings have suggested that communication techniques that can create a narrative, engage emotion, make the abstract more understandable, and use value frames to connect to an audience and encourage empathy will be most effective in encouraging behavioral change. The arts are capable of communicating in this fashion; sounding art in particular has a long history of engaging with politicized and emotional issues in ways that can ultimately provoke large-scale shifts in social convention. The arts and sciences each provide important responses to environmental problems. When used together, however, they have serious potential to create change. Data sonification, or the translation of data into sound, combines climate science and ecological art into a potentially powerful form of environmental activism. This thesis research examines the technique’s blend of art and science and its potential as effective environmentalist art through an exploration of three case studies: Lauren Oakes and Nik Sawe’s 2016 sonification of climate change impacts on Alaskan forests, Andrea Polli’s 2004 online sonification project Heat and the Heartbeat of the City, and the 2012 telematic multimedia opera Auksalaq by Matthew Burtner and Scott Deal. Data sonifications defy classification as either solely artistic or scientific—this disciplinary ambiguity can create tension—but it is exactly this disciplinary ambiguity that makes them useful as environmentalist tools. Sonifications appeal to emotions and logic and require creativity and evidence, powerful persuasive combinations in the face of environmental issues. They require scientists to consider the aesthetics behind the art, and composers to understand the science behind the data; in forcing us to acknowledge the importance of the other disciplinary perspective, they help us to question some of our disciplinary boundaries and effectively serve as a model for the interdisciplinary collaboration that is increasingly necessary as we navigate our changing world. / A Thesis submitted to the College of Music in partial fulfillment of the requirements for the degree of Master of Music. / Spring Semester 2019. / March 29, 2019. / Climate Change, Data Sonification, Ecological Art, Environmental Sustainability, Interdisciplinary Art, Science Communication / Includes bibliographical references. / Denise Von Glahn, Professor Directing Thesis; Sarah Eyerly, Committee Member; Michael Broyles, Committee Member; Jeffrey Chagnon, Committee Member.

For the globalization competition, high-speed progress of new technology and science etc., the environment of enterprises operation is fast changing now, in the face of so fast environmental changes, propose and implement effective organizational changes activities only, it is crucial to enterprises survival and continuous growth. By the practice of organizational changes, change activities could be separated into several types, like manufacturing management related, or organizational structure related etc., and CRM belong to marketing function related. Recently, for meet the various demands from customer, enterprises begin to pay attention on customer relationship management, and CRM becomes one of the change activities that the business circles make earnest efforts to promote. In different organizational changes activities, what is the Human Resources Department positioning and role? and how to help enterprises to reach the goal of change activities? That is the Human Resources Department and staff member must pay attention to for now . This research makes use of one case that enterprise implement CRM activity, to study the role of Human Resources Department and the relevant activities in CRM and other organizational changes activities in enterprises, the main conclusions are as follows: 1. When the Human Resources Department facing the change activities in enterprises, it must jump and take off the myth of that HR must be the ¡¥change agent¡¦, it should recognize and understand what¡¦s the limitation of itself, then getting more careful to choose and act the correct role. 2. In enterprises changes activities, if Human Resources Department can not to be the change agent, then it should act the role of key support, assistance and communicating, besides, it should initiate and conduct the related project in its own department to feedback and echoed the organizational changes activities.
