The climate change agenda is populated by actors and agencies with different objectives, values, and motivations, yet many seek decision scale climate information to inform policy and adaptation responses. A central element of this network of activity is the climate information website (CIW) that has seen a rapid and organic growth, yet with variable content and quality, and unfettered by any code of practice. This builds an ethical–epistemic dilemma that warrants assessment as the presence of CIWs contribute to real‐world consequences and commitment. This study considers the context of CIW growth, and reviews a representative sample of CIWs to draw out key issues for consideration in CIW development. We assess content, function, and use‐case value through a dual approach of a typology and user experience narratives to evaluate the general efficacy of a CIW. The typology reveals strong contrasts in content, complicated interfaces, and an overload of choice making it difficult to converge on a stable outcome. The narratives capture user experience and highlight barriers that include navigation difficulties, jargon laden content, minimal or opaque guidance, and inferred information without context about uncertainty and limits to skill. This illuminates four concerns: (1) the ethics of information provision in a context of real‐world consequences; (2) interfaces that present barriers to achieving robust solutions; (3) weak capacity of both users and providers to identify information of value from the multimodel and multimethod data; and (4) inclusion of data that infer skill. Nonetheless, results provide a positive indication of a community of practice that is still maturing.

Cities play increasingly recognised roles in global climate change responses: as change laboratories, spaces of opportunity, and as administrative and economic hubs that concentrate human and financial resources and needs. They host high climate mitigation potential and acute climate adaptation vulnerabilities. Scholarship flags conventional urban planning approaches to limit global warming to 1.5°C as inadequate. Yet urban sustainability transitions literature features few examples of functioning alternative governance and planning paradigms. This paper assesses one such approach, new municipalism: social movements centred on a democratic transformation of the local economy and state. We combine attention to urban sustainability transitions and new municipalism research to interrogate whether and how the latter can facilitate the provision of leadership and institutional arrangements that enable urban transformation to sustainability. Our desk study considers two prominent examples of new municipalism in Spain, where Barcelona en Comú and Ahora Madrid arose as anti-austerity movements to combat neoliberal urban agendas during the 2010s. We find that the praxis of collective decision-making associated with new municipalism does offer inclusive, innovative policy pathways and the potential to implement experimental knowledge and learning in complex real-world settings at the urban scale. We argue, however, that powerful neoliberal mechanisms impose structural constraints on the very push for deep political change that new municipalist movements embody. By linking transformative climate governance needs with new municipalism movements and wider political economic structuring forces, we explicate the tensions and contested dynamics of institutionalising progressive social movements in the multi-scalar governance of urban sustainability transformation.

Given that climate change is a complex, systemic risk, addressing it requires new knowledge. One way of generating such new knowledge is through co-production, or collaborative development by a range of stakeholders with diverse backgrounds embedded in trans-disciplinary processes. This chapter reflects on emerging experiences of co-producing decision-relevant climate information to enable climate-resilient planning and adaptation to climate change in Africa. It outlines principles that have emerged and evolved through experiential learning from a wide range of co-production processes in Africa. It also uses case study experience from various contexts to highlight some of the more contextual challenges to co-production such as trust, power and knowledge systems and institutional factors (mandates, roles and incentives) and illustrates ways that trans-disciplinary co-production has addressed these challenges to mainstream a response to the climate challenge.
