“…The aforementioned CETA and MERGE models are also dynamic equilibrium frameworks. In later years, many more neoclassical growth model-based IAMs were developed, often building on DICE directly or indirectly, as discussed in Section V. See also later literature reviews such as Nordhaus (2013a), Weyant (2017), and Hassler et al (2016). "A useful analogy here is to the animal kingdom.…”

Demand-side approaches for limiting global warming to 1.5 °C

The Paris Climate Agreement defined an ambition of limiting global warming to 1.5°C above preindustrial levels. This has triggered research on stringent emission reduction targets and corresponding mitigation pathways across energy economy and societal systems. Driven by methodological considerations, supply side and carbon dioxide removal options feature prominently in the emerging pathway literature, while much less attention has been given to the role of demand-side approaches. This special issue addresses this gap, and aims to broaden and strengthen the knowledge base in this key research and policy area. This editorial paper synthesizes the special issue's contributions horizontally through three shared themes we identify: policy interventions, demand-side measures, and methodological approaches. The review of articles is supplemented by insights from other relevant literature. Overall, our paper underlines that stringent demand-side policy portfolios are required to drive the pace and direction of deep decarbonization pathways and keep the 1.5°C target within reach. It confirms that insufficient attention has been paid to demand-side measures, which are found to be inextricably linked to supply-side decarbonization and able to complement supply-side measures. The paper also shows that there is an abundance of demand-side measures to limit warming to 1.5°C, but it warns that not all of these options are Bseen^or captured by current quantitative tools or progress indicators, and some remain insufficiently represented in the current policy discourse. Based on the set of papers presented in the special issue, we conclude that demand-side mitigation in line with the 1.5°C goal is possible; however, it remains enormously challenging and dependent on both innovative technologies and policies, and behavioral change. Limiting warming to 1.5°C requires, more than ever, a plurality of methods and integrated behavioral and technology approaches to better support policymaking and resulting policy interventions.

“…Recent developments in these models tended to expand the system boundaries and increase the heterogeneity of the various components represented, and increasingly challenging questions are being asked, requiring 'coupling of IAMs to hydrological models and possibly earth system models to study feedbacks among these systems ' Krey (2014). Similarly, Weyant (2017) surveyed IAMs, dividing them into those focused on benefit-cost analysis and those focused on detailed process representations. They noted that emerging challenges for IAMs include which climate change impacts to include, how to represent extremes, and how to capture feedbacks both within the human system and between the human and Earth system.…”

Integrated human-earth system modeling—state of the science and future directions

Research on humans and the Earth system has historically occurred separately, with different teams and models devoted to each. Increasingly, however, these communities and models are becoming intricately linked. In this review, we survey the literature on integrated human-Earth system models, quantify the direction and strength of feedbacks in those models, and put them in context of other, more frequently considered, feedbacks in the Earth system. We find that such feedbacks have the potential to alter both human and Earth systems; however, there is significant uncertainty in these results, and the number of truly integrated studies remains small. More research, more models, and more studies are needed to robustly quantify the sign and magnitude of human-Earth system feedbacks. Integrating human and earth models entails significant complexity and cost, and researchers should carefully assess the costs and benefits of doing so with respect to the object of study.
