Adaptation is a key societal response to reduce the impacts of climate change, yet it is poorly represented in current modelling frameworks. We identify key research gaps and suggest entry points for adaptation in quantitative assessments of climate change to enhance policy guidance.
Adaptation refers to the process by which societies adjust to existing and expected impacts of climate change. Adaptation on the ground is determined by prevailing regional and contextual conditions, and shaped by diverse societal actors.
The positive benefits of adaptation, such as risk reduction, vary greatly depending on enabling or constraining conditions, with effects usually seen at the local or regional level. Unlike for mitigation (reducing greenhouse gas emissions), there is no universal metric to assess the wide range of adaptation outcomes. This makes it hard to gauge how effective adaptation measures are in response to different climate impacts in a quantifiable manner on an aggregate scale. As a result, adaptation is poorly represented in global quantitative models used in climate research.
Where adaptation is represented, it is either highly stylized or constrained to specific options in selected sectors. As a consequence, there is limited global evidence on the costs and ability of adaptation to respond to mounting climate risks, which leads to an under-representation of adaptation when evaluating climate policy costs.
Moreover, there is a clear need to understand how adaptation and mitigation interact — the two policy strategies have mostly been investigated in isolation, including in IPCC reports.
Hitzestress und Anpassungsmaßnahmen in der Metropolregion Berlin-Brandenburg
Städte sind dabei besonders anfällig für Hitzestress. Deshalb betrachten wir in diesem Bericht die Folgen des Klimawandels auf die Metropolregion Berlin-Brandenburg, mit einem speziellen Fokus auf die Auswirkungen von Hitzestress und die Entwicklung von Anpassungsstrategien.
Climatic risks to adaptive capacity
A society’s adaptive capacity determines whether the potential of adaptation to reduce risks will be realised. In this paper, we make the case that climate change itself adds to adaptation constraints and limits.
Machine learning evidence map reveals global differences in adaptation action
In this study, we tracked how adaptation policy research has changed globally to create a map of how governments around the world use different tools at different levels and in different regions. We found that while the evidence base is growing, most of this evidence, however, comes from the Global North.
Defining a Regional Goal on Adaptation for the Caribbean
While the Global Goal on Adaptation provides a collective goal for adapting to climate change, adaptation is often a context specific and localised process. This paper proposes a Regional Goal on Adaptation for the Caribbean based on priorities relevant for Caribbean small island developing states.
Adaptation constraints in scenarios of socio-economic development
Here, we combine data on documented adaptation from the Global Adaptation Mapping Initiative with national macro indicators and assess future changes in adaptation constraints alongside the Shared Socioeconomic Pathways, spanning a wide range of future socio-economic development scenarios.
Towards scenario representation of adaptive capacity for global climate change assessments
Climate change adaptation needs, as well as the capacity to adapt, are unequally distributed around the world. Here we propose ways to quantify adaptive capacity within the framework of Shared Socioeconomic Pathways, a scenario set widely used by climate impact and integrated assessment models.
Risks of synchronised low yields are underestimated in climate and crop model projections
This study finds that the jet stream – air currents in the upper atmosphere – can synchronise extreme weather caused by climate change, resulting in crop failures in multiple countries at the same time.
De la CDN 1.0 à la CDN 2.0: qu'est-ce qui a changé dans les CDN des PMA de l’Afrique de l'Ouest?
La présente étude examine les premières et les secondes Contributions Déterminées au niveau National des onze pays les moins avancés de l’Afrique de l’Ouest à savoir le Bénin, le Burkina Faso, la Gambie, la Guinée, la Guinée Bissau, le Libéria, le Mali, le Niger, le Sénégal, la Sierra Leone et le Togo.
Interacting adaptation constraints in the Caribbean highlight the importance of sustained adaptation finance
Long term strategies: low carbon growth, resilience and prosperity for Least Developed Countries
Long-term, low greenhouse gas emission development strategies provide a beneficial space for Least Developed Countries to set out a visionary blueprint for a resilient, decarbonised future, compatible with limiting warming to 1.5°C.
