The role and design of global expert organizations such as the Intergovernmental Panel on Climate Change (IPCC) or the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) needs rethinking. Acknowledging that a one-size-fits-all model does not exist, we suggest a reflexive turn that implies treating the governance of expertise as a matter of political contestation.

Society is vulnerable to extreme weather events and, by extension, to the human impact on future events. As climate changes weather patterns will change. The search is on for more effective methodologies to aid decision-makers both in mitigation to avoid climate change and in adaptation to changes. The traditional approach employs ensembles of climate model simulations, statistical bias correction, downscaling to the spatial and temporal scales relevant to decision-makers, and then translation into quantities of interest. The veracity of this approach cannot be tested, and it faces in-principle challenges. Alternatively, numerical weather prediction models in an altered climate setting can provide tailored naritives of high-resolution simulations of high-impact weather in a future climate. This Tales of Future Weather approach will aid in the interpretation of lower resolution simulations. Arguably, it potentially provides a complementary and more realistic and more physically consistent pictures of what future weather might look like.

a b s t r a c tRenewable energy communities have multiplied the last years in many countries, even in contexts that the structural conditions are not favorable. The paper analyses individual motivations for partaking in local renewable projects and generating energy jointly in an investment community, in order to inform policy debates on how to support such communities. To do so, we applied a socio-psychological approach for studying renewable energy communities in Germany and the Netherlands. Our results show that mainly gain (such as decreasing energy costs) and normative (such as addressing climate change) considerations played a role in the decision, but in the background hedonic motivations were also present, such as having fun and integrating in a community. Each of the groups examined emerged in already existing strong communities, where trust was relatively high, which seems to be an important condition for the realization of local energy projects. Consequently, we argue that tailor-made incentives addressing the different types of motivations can be more effective for the support and spread of renewable energy communities.
