There is increasing agreement among Australian policymakers and stakeholders that climate change the biggest problem facing Great Barrier Reef. However, little known about whether this convergence shapes perspectives on solutions. To understand different actor solutions for Reef, we applied a 'problem-solution' framework employing Q-methodology to guide in-depth interviews with engaged actors. We found despite growing over problem, significant divergence remains. identified six generalised ranging from technology-led adaptation at one end of spectrum radical transitions other. support market-led, regionally-led, represents new shift toward transformational policy beyond conventional bounds GBR governance. multiple divergent suggest more reflexive learning required effectively govern critical ecosystem into future.

Abstract Solar geoengineering maintains a vocal presence as stop-gap measure in assessments of climate and sustainability action. In this paper, we map prospective benefits risks, corresponding governance approaches, regarding three major proposals for solar (stratospheric aerosol injection, marine cloud brightening, space-based sunshield). We do so by engaging with 44 focus groups conducted 22 countries split between the global North South. compare results against previous research on public perceptions well wider activities assessment, innovation, decision-making. find that South exhibit greater hope but an arguably richer range concerns geoengineering, context observable inequities action potential geopolitical conflict. Meanwhile, strong, preference multilateral coordination engagement from conduct onwards is offset skepticism effective multilateralism discourse.

Carbon dioxide removal and negative emissions technologies, such as bioenergy with carbon capture (BECCS) direct air storage (DACCS), may have an important role to play in reducing greenhouse gas (GHGs). Cloud seeding (CS), a controversial form of weather modification, might also help reduce the severity intensity storms address widespread drought from climate change. Nevertheless, costs, technical complexity, social acceptance, other unknown risks so far kept these geoengineering interventions at uncertin levels research deployment response Although large corpus literature sufficiently deals aspects underlying interventions, nontechnical mark fertile territory. This study applies sociotechnical concept Multi-Level Perspective (MLP)—commonly used for analysis sustainability transitions—to explore risks, uncertainties, complexities rolling out BECCS United Kingdom, DACCS States, cloud Australia. We examine interaction MLP across three (niche, regime, landscape), then windows opportunity technological transition bottlenecks. Specifically, we show that align "stretch-and-transform" transition, can be construed "fit-and-conform", CS seen within "stretch-and-conform."

Efforts to halt the precipitous decline of marine ecosystems are taking on additional importance in relation discussions climate change and carbon removal. Out all biological captured world, more than half is stored by living organisms, oceans represent largest long-term sink for carbon. Blue carbon, preservation enhancement coastal removal, treated as a potentially cost-effective way capture store generate community co-benefits, implement conservation agendas. However, blue among most unproven intervention options, part given their status highly threatened systems which moreover have critical connections planetary health food security. Based extensive place-based field research document analysis, this study examines three innovations: coral reef Australia, seagrass restoration United Kingdom, macroalgae (seaweed) cultivation deep ocean storage States. Empirically, it utilizes an extensive, original dataset expert interviews (N=46), site visits (N=38) analysis undertaken over late 2022 2023. Conceptually, advances our understanding typologies related narratives ideographs, innovation technological styles, co-impacts. It thus offers comparative case work across locations approaches with mixed-methods data aimed at novel theoretical triangulation typological frameworks.

Abstract As countries and communities grapple with climate change, they seek to rapidly decarbonize their economies cultures. A low‐carbon future will likely depend on more distributed solar energy, the electrification of mobility, efficient homes buildings. But what emergent risks are evident within this society? This exploratory study first reviews existing literature identify 75 risk–risk tradeoffs by category, medium distribution, type. It builds these examples apply a typology Risk Offsets, Substitution, Transfer, Transformation. Based extensive document analysis, it applies that three innovations: battery electric vehicles, building energy efficiency retrofits, identifying 36 distinct in total. such, paper moves discuss complexities challenges risk management. In doing so, calls for refined assessment better accounts decision‐making considerations such as magnitude or probability risk, size population exposed, certainty estimation, severity adverse outcome, distributional considerations, timing impacts. also summarizes research gaps. management context action becomes three‐dimensional chess game weighing transmission, mediums, categories.

Abstract Marine Cloud Brightening (MCB) is a proposed Solar Radiation Modification (SRM) geoengineering technique to enhance Boundary Layer (MBL) cloud albedo. Extant proposals consider 10 4 − 5 autonomous ships spraying seawater, generating and dispersing sea salt nanoparticles. Alternatively, this paper proposes industrially manufacturing NaCl nanoparticles using ethanol anti-solvent brine precipitation. With desiccation, size optimization narrowed distribution, aerosol mass flux reduces by ∼500× (17× for dry flux). This facilitates Unmanned Aerial Vehicle delivery (e.g. MQ-9 Reaper Vehicle). Increased speed wake turbulence improves areal coverage per vehicle versus ships—reducing fleet size. Utilizing extant airframe designs Technology Readiness Level (TRL)—potentially improving system operational cost (est. $40 B · yr −1 ) lead time. approach further energy requirements (5× less), technical risk complexity. readiness amplifies proliferation risk—particularly inexpensive regional heatwave hurricane suppression—making governance more urgent.
