C2G Evidence Brief: Carbon Dioxide Removal and Its Governance
Carnegie Climate EVIDENCE BRIEF Governance Initiative Carbon Dioxide Removal An initiative of and its Governance 2 March 2021 Summary This briefing summarises the latest evidence relating to Carbon Dioxide Removal (CDR) techniques and their governance. It describes a range of techniques currently under consideration, exploring their technical readiness, current research, applicable governance frameworks, and other socio-political considerations in section I. It also provides an overview of some generic CDR governance issues and the key instruments relevant for the governance of CDR in section II. About C2G The Carnegie Climate Governance Initiative (C2G) seeks to catalyse the creation of effective governance for climate-altering approaches, in particular for solar radiation modification (SRM) and large-scale carbon dioxide removal (CDR). In 2018, the Intergovernmental Panel on Climate Change (IPCC) reaffirmed that large-scale CDR is required in all pathways to limit global warming to 1.5°C with limited or no overshoot. Some scientists say SRM may also be needed to avoid that overshoot. C2G is impartial regarding the potential use of specific approaches, but not on the need for their governance - which includes multiple, diverse processes of learning, discussion and decision-making, involving all sectors of society. It is not C2G’s role to influence the outcome of these processes, but to raise awareness of the critical governance questions that underpin CDR and SRM. C2G’s mission will have been achieved once their governance is taken on board by governments and intergovernmental bodies, including awareness raising, knowledge generation, and facilitating collaboration. C2G has prepared several other briefs exploring various CDR and SRM technologies and associated issues. -

ROUGH SEAS AHEAD: NAVIGATING the INEQUALITIES of FUTURE SEA-LEVEL RISE by Robert Dean Hardy (Under the Direction of Marguerite M
ROUGH SEAS AHEAD: NAVIGATING THE INEQUALITIES OF FUTURE SEA-LEVEL RISE by Robert Dean Hardy (Under the Direction of Marguerite Madden) ABSTRACT With anthropogenic climate change poised to accelerate sea-level rise this century, millions of everyday lives and livelihoods are predicted be unevenly vulnerable to this social- ecological change. In this dissertation, I examine both outcome and contextual vulnerability by applying an integrative approach as my research design framework to navigate the problem of inequalities related to future sea-level rise. To apply mixed methods and plural epistemologies that move from the global to the local scale, I examined the inequalities of sea-level rise via three routes: (1) a global scale, quantitative analysis of country responsibility and risk related to multi- millennial sea-level rise; (2) a regional scale, quantitative analysis of spatiotemporal variation in risk to sea-level rise through the year 2050 for coastal Georgia; and (3) a comparative case study of two barrier island communities off the coast of Georgia, Tybee and Sapelo Islands, to show how race shapes vulnerability to sea-level rise. The are three primary findings for this dissertation: (1) our assessment of future populations’ social vulnerability to sea-level rise inundation indicates that the number of people at risk to sea-level rise on Georgia’s coast is more than double previous estimates that were based on 2010 population data; (2) acknowledgement and acceptance – by the professional community working on sea-level rise – of race as a process of enabling or constraining meaningful engagement, rather than as a mere demographic category, will help mitigate vulnerability for underrepresented communities; and (3) investigating the vulnerability to sea-level rise of a culture and/or place through narrative analysis of its stories and histories is strengthened by modeled projections of sea-level rise inundation and population change. -
Islands Submerged Into the Sea Islands in the Cultural Imaginary of Climate Change by Camilla Asplund Ingemark
Islands Submerged into the Sea Islands in the Cultural Imaginary of Climate Change By Camilla Asplund Ingemark Islands are a fascinating subject from many points of view; this is one thing Owe Ronström’s persistent enthusiasm for islands and island studies has taught me, as his most junior and recent colleague. They appeal to our (West- ern) imagination as sites of projection for our various desires – and aversions – which becomes especially clear in the context I intend to examine here: discourses on climate change and the peculiar role islands, sinking islands in particular, seem to play in it. I suspect my sudden and fervent interest in this motif in the contemporary cultural imaginary of climate change would not have arisen without Owe’s infuence, and in the following discussion I will especially be drawing on his articulation of the components of “islandness” in Öar och öighet (2016). Thus, I propose to study the recurrent motif of islands being submerged into the sea in texts and narratives on climate change. I am interested in why this image of sinking islands occupies such a prominent place in the con- temporary representation of climate change, and more generally, why it is so compelling to the Western imagination. Drawing on various forms of media content as well as vernacular texts, I attempt to trace the emergence of this motif as one of a handful of iconic images we commonly use to represent and visualize climate change – alongside the polar bear on its dwindling ice foe, melting glaciers etc. – and in the case of the vernacular texts, how this image is employed rhetorically to articulate a specifc stance vis-à-vis climate change. -

Has Climate Change Rendered the Concept of Sovereignty Obsolete? Marcus Arcanjo January 2019
Has Climate Change Rendered the Concept of Sovereignty Obsolete? Marcus Arcanjo January 2019 Introduction Since the 1648 Treaty of Westphalia, state sovereignty has been the driving force underpinning the independence of countries, giving them right to exist via decisions from an organised government without outside intervention. Further, it has traditionally been ‘used to legitimize a strong and undivided power that could secure law and order in times of civil and religious wars’’.1 The 1933 Montevideo Convention on the Rights and Duties of states determined that to be recognised as a state in international law, there must be: a permanent population, a defined territory, functioning government, and the ability to engage in relations with other states. Whilst such qualifications are seemingly straightforward, they do not take into account the threat of climate change, which was very much in the background at the time. Currently, a rapidly changing climate is placing island states and atoll nations in particular risk of becoming submerged due to rising sea levels.2 Unless the concept of sovereignty is revised, there will be a growing list of populations that are undefined and undefinable populations under current international law, which could well lead to global crisis and international instability. In this paper I argue that national sovereignty is not obsolete, but rather the concept must be redefined to take into account the effects of a changing climate. The core argument suggests that the discourse should shift away from whether sovereignty is useless and instead focus on the development of an all-encompassing definition for statehood, in order to protect the rights of countries and their citizens in the face of climate change, especially regarding the physical disappearance of their territory. -
Climate Engineering Field Research: the Favorable Setting of International Environmental Law
Climate Engineering Field Research: The Favorable Setting of International Environmental Law Jesse Reynolds* Abstract As forecasts for climate change and its impacts have become more dire, climate engineering proposals have come under increasing consideration and are presently moving toward field trials. This article examines the relevant international environmental law, distinguishing between climate engineering research and deployment. It also emphasizes the climate change context of these proposals and the enabling function of law. Extant international environmental law generally favors such field tests, in large part because, even though field trials may present uncertain risks to humans and the environment, climate engineering may reduce the greater risks of climate change. Notably, this favorable legal setting is present in those multilateral environmental agreements whose subject matter is closest to climate engineering. This favorable legal setting is also, in part, due to several relevant multilateral environmental agreements that encourage scientific research and technological development, along with the fact that climate engineering research is consistent with principles of international environmental law. Existing international law, however, imposes some procedural duties on States who are responsible for climate engineering field research as well as a handful of particular prohibitions and constraints.

It was a challenging argument in many ways: ,irstly, it was challenging to reconstruct a reasonable version of this argument, that adds to and clarifies the current discussion about a potential buying time deployment of climate engineering. Secondly, it challenged my own point of view about climate engineering. 7hile intuitively, I would headlong reAect any use of climate engineering, analyzing the buying time argument made me concede that there might be forms of deployment that actually could be beneficial and morally sound, albeit in very strict boundary conditions. -
