MARINE CLOUD BRIGHTENING Alan Gadian , John Latham, Mirek Andrejczuk, Keith Bower, Tom Choularton, Hugh Coe, Paul Connolly, Ben Parkes, Phillip Rasch, Stephen Salter, Hailong Wang and Rob Wood . Contents:- • Background to the philosophical approach • Some L.E.M . and climate model results • Technological issues. • Future plans and publications. Science Objectives:- • To explain the science of how stratocumulus clouds can have a significant effect on the earth’s radiation balance • To present some modelling results from Latham et al 2011 Marine Cloud Brightening, WRCP October 2011 1 Stratocumulus clouds cover more than 30% of ocean surface Stratocumulus clouds have a high reflectance, which depends on droplet number and mean droplet size. Twomey Effect .:- Smaller drops produce whiter clouds . Proposal :- To advertently to enhance the droplet concentration N in low-level maritime stratocumulus clouds, so increasing cloud albedo (Twomey, JAS, 1977 ) and longevity ( Albrecht, Science, 1989 ) Technique:- To disseminate sea-water droplets of diameter about 1um at the ocean surface. Some of these ascend via turbulence to cloud-base where they are activated to form cloud droplets, thereby enhancing cloud droplet number concentration, N (Latham, Nature 1990 ; Phil Trans Roy Soc 2008 and 2011, under review ) 2 Above:- Computed spherical albedo for increasing pollution in THIN, MEDIUM and THICK clouds. ( Twomey, JAS, 1977 ) Right:- Frequency distributions of the reflectances at 1,535 nm versus reflectances at 754 nm. From ACE-2. Isolines of geometrical thickness (H) and droplet number concentration (N): higher reflectance in polluted cloud, normalised by a similar geometrical thickness (Brenguier et al. 2000 ). 3 Figure 1.

Climate Change, Consequentialism, and the Road Ahead Dale Jamieson* Abstract In this paperI tell the stoy of the evolution of the climate change regime, locating its origins in "the dream of Rio," which supposed that the nations of the world would join in addressing the interlocking crises of environment and development. I describe the failure at Copenhagen and then go on to discuss the "reboot" of the climate negoiations advocated by Eric A. Posner and David Weisbach. I bring out some ambiguides in their notion of InternationalPareianism, which is supposed to effectively limit the influence of moral ideals in internationalaffairs, and pose a dilemma. I go on to discuss the foundations of their views regarding climate justice, arguing that the most reasonable understandings of their favored theoretical views would not lead to some of their conclusions. Finaly, I return to the climate regime, and make some observations about the road ahead, concluding thatfor theforeseeable future the most important climate change action will be within countries rather than among them. -

Equitably Ending the Fossil Fuel Era: Climate Justice, Capital, & the Carbon Budget Georges Alexandre Lenferna A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2019 Reading Committee: Stephen Gardiner, Chair Carina Fourie Aseem Prakash Michael Blake Program Authorized to Offer Degree: Department of Philosophy 1 ©Copyright 2019 Georges Alexandre Lenferna 2 University of Washington Abstract Equitably Ending the Fossil Fuel Era: Climate Justice, Capital, & the Carbon Budget Georges Alexandre Lenferna Chair of the Supervisory Committee: Stephen Gardiner Department of Philosophy This dissertation makes the moral case for equitably transitioning away from fossil fuels in line with keeping global warming as close as possible to the Paris Climate Agreement’s more stringent target of keeping global warming to 1.5°C above pre-industrial levels. It argues that we should do so while relying as little as possible on risky and uncertain negative emissions and geoengineering technologies, as doing so might prolong the fossil fuel era and pose grave potential costs both to the present and future generations. The dissertation addresses a central objection to the moral imperative to transition away from fossil fuels, namely that it will detrimentally impact the poor and vulnerable. It argues in response that protecting the interests of the poor and vulnerable is best achieved through a rapid yet just transition away from fossil fuels. Based on the moral case to transition away from fossil fuels in line with 1.5°C the dissertation also explores what personal moral responsibility individuals have to take action to reduce fossil fuel usage and act on climate change. -

Climate Litigation and Atmospheric Ethics: a Case Study of Juliana V
CLIMATE LITIGATION AND ATMOSPHERIC ETHICS: A CASE STUDY OF JULIANA V. UNITED STATES Mark Ortiz A thesis submitted to the faculty at the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Master of Arts in the Department of Geography. Chapel Hill 2017 Approved By: Elizabeth Olson Elizabeth Havice Scott Kirsch ©2017 Mark Ortiz ALL RIGHTS RESERVED ii ABSTRACT Mark Ortiz: Climate Litigation and Atmospheric Ethics: A Case Study of Juliana v. United States (Under the Direction of: Drs. Elizabeth Olson and Elizabeth Havice) This thesis offers an account of climate change lawsuits as ethical experiments which endeavor to develop legal and ethical norms and principles suited to a world remolded by cumulative human actions. It offers a theorization of the ‘what’ and the ‘why’ of the growing, global wave of climate litigation by situating it within the dynamic landscape of contemporary climate politics. Through a case study of Juliana v. United States, a first-of-its-kind constitutional climate lawsuit against the United States federal government, this thesis examines how legal narrative is mobilized to give ethical shape and significance to the problem of climate change and to conceptualize responsibility across vast sweeps of space and time. Interweaving insights from climate ethics, environmental humanities, legal geography and science and technology studies, this research offers a set of meditations on atmospheric ethics iii TABLE OF CONTENTS CHAPTER 1: INTRODUCTION: CLIMATE LITIGATION AS ETHICAL EXPERIMENTATION ................................................................................................. 1 1.1 Introduction ................................................................................................................... 1 1.2 Methods, Approach and Plan of the Present Work ....................................................... 5 1.3 Climate Ethics: Sculpting the Climatic Citizen ........................................................... -

Climate Intervention (July 2021)
State of the Science FACT SHEET Climate Intervention Climate Intervention (CI), also called climate engineering or geoengineering, refers to deliberate, large‐scale actions intended to counteract aspects of climate change. This Fact Sheet explains some of the fundamental principles and issues associated with CI (1). Why Might Climate Intervention Be Considered? The main driver of climate change over the past century has been anthropogenic emissions of carbon dioxide (CO2), a greenhouse gas (GHG). Increasing emission rates have caused present‐day atmospheric CO2 to reach the highest value in over a million years based on studies of emissions of atmospheric CO2 and its accumulation in the atmosphere, ocean, and terrestrial biosphere. The increased emissions of other GHGs, such as methane, nitrous oxide and ozone, also contribute to anthropogenic climate change. The increased accumulation of GHGs has led to warming over much of the globe, to acidification of ocean surface waters (from CO2) (2), and to many other well‐documented climate impacts (3). As climate change continues, if the world does not make the desired greenhouse gas emissions reductions (4) such as those initiated by the Paris agreement (5), governments and other entities might turn to CI to counteract increasing climate change impacts. CI could potentially be implemented by consensus or unilaterally; either way, a thorough understanding of CI methods, and their associated uncertainties and unintended side effects is essential. Principal CI methods are divided into two How might CDR be accomplished? general categories (6) (see figure): Oceanic sequestration: Adding nutrients, such as iron, to “ferti‐ lize” the ocean enhances biological growth (e.g., phytoplank‐ Carbon dioxide removal (CDR): CDR is a process to remove ton), which removes CO2 from surface waters and leads to lower CO2 from the atmosphere for long‐term storage on land or atmospheric levels. -

Keith∗ Draft: 8 May 2018 This paper introduces geoengineering into an optimal control model of climate change economics. Together with mitigation and adaptation, carbon and solar geoengineering span the universe of possible climate policies. Their wildly different characteristics have important implications for climate policy. We show in the context of our model that: (i) the optimal carbon tax equals the marginal cost of carbon geoengineering; (ii) the introduction of either form of geoengineering leads to higher emissions yet lower temperatures; (iii) in a world with above-optimal cumulative emissions, only a complete set of instruments can minimize climate damages. -
The Need for Virtue in an Age of Climate Change a Thesis Presented
The Need for Virtue in an Age of Climate Change A thesis presented to the faculty of the College of Arts and Sciences of Ohio University In partial fulfillment of the requirements for the degree Master of Arts in Philosophy Zachary R. Allison August 2018 © 2018 Zachary R. Allison. All Rights Reserved. 2 This thesis titled The Need for Virtue in an Age of Climate Change by ZACHARY R. ALLISON has been approved for the Philosophy Department and the College of Arts and Sciences by Scott Carson Associate Professor of Philosophy Joseph Shields Interim Dean, College of Arts and Sciences 3 ABSTRACT ALLISON, ZACHARY R., M.A., August 2018, Philosophy The Need for Virtue in an Age of Climate Change Director of Thesis: Scott Carson Dale Jamieson, Stephen Gardiner, Allen Thompson, and Byron Williston are four of the most prominent philosophers who have written on the role that virtue plays in an age of climate change. None of them, however, consider how valuable virtue can be in serving preventative ends. Climate change is, in part, a moral failure and part of the task of mitigating climate change should be acknowledging this failure and working to make sure we do not commit the same mistakes of the past. In this thesis, I argue for the cultivation of a virtue that I call “holism” that I believe can help humanity achieve this end. In chapter one, I discuss the arguments of the aforementioned philosophers and identify how their views of virtue in the Anthropocene are not identical to my own. In chapter two, I spell out the virtue of holism and argue for how it can help humanity work towards not allowing another climate catastrophe to happen once the present crisis is mitigated. -
Ethics and the Economist: What Climate Change Demands of Us

Nelson May 2011 Tufts University Medford MA 02155, USA http://ase.tufts.edu/gdae This working paper is also available as an E3 (Economists for Equity and the Environment, e3network.org/) White Paper. A revised version will be published in Ecological Economics. Copyright 2011 Global Development and Environment Institute, Tufts University GDAE Working Paper No. 11-02: Ethics and the Economist: What Climate Change Demands of Us Abstract: Climate change is changing not only our physical world, but also our intellectual, social, and moral worlds. We are realizing that our situation is profoundly unsafe, interdependent, and uncertain. What, then, does climate change demand of us, as human beings and as economists? A discipline of economics based on Enlightenment notions of mechanism and disembodied rationality is not suited to present problems. This essay suggests three major requirements: first, that we take action; second, that we work together; and third, that we focus on avoiding the worst, rather than obtaining the optimal. The essay concludes with suggestions of specific steps that economists can take as researchers, teachers, and in our other roles. Keywords: climate change; ethics; catastrophe; uncertainty; interdependence; Enlightenment; responsibility; embodied reason 1 GDAE Working Paper No. 11-02: Ethics and the Economist: What Climate Change Demands of Us Ethics and the Economist: What Climate Change Demands of Us J.

Damon Matthews, Richard Millar, Armon Rezai, Susan Solomon, and Frank Venmans* Lemoine and Rudik 2017 argues that it is efficient to delay reduc- ing carbon emissions(, due )to supposed inertia in the climate system’s response to emissions. This conclusion rests upon misunderstand- ing the relevant earth system modeling: there is no substantial lag between CO2 emissions and warming. Applying a representation of the earth system that captures the range of responses seen in complex earth system models invalidates the original article’s implications for climate policy. The least-cost policy path that limits warming to 2°C implies that the carbon price starts high and increases at the interest rate.
