This article provides a review of recent scientific literature on social vulnerability to climate change, aiming to determine which social and demographic groups, across a wide range of geographical locations, are the most vulnerable to climate change impacts within four well-being dimensions: health, safety, food security, and displacement.
We analyse how vulnerability changes over time and ask whether there is evidence of critical thresholds beyond which social vulnerability drastically changes.
The review finds that climate change is expected to exacerbate current vulnerabilities and inequalities. The findings confirm concerns about climate justice, especially its intergenerational dimensions. For example, deficiencies in early childhood may limit future educational and income generation opportunities. Evidence of clear thresholds is rare and is mainly related to the vulnerability of different age groups, household income level, and the impacts of different degrees of global warming.
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.
Coastal loss and damage for small islands
This commentary on a paper in Nature Sustainability reviews how the study quantifies the impacts of sea-level rise on small island states and estimates the impacts in terms of cost, land loss and population exposure across all small islands worldwide.
The effects of political knowledge use by developing country negotiators in Loss and Damage negotiations
This article traces how developing country negotiators used knowledge to further their interests in loss and damage negotiations from 2003 to 2013.
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.
Representation of adaptation in quantitative climate assessments
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.
Research agenda for the loss and damage fund
This piece in Nature discusses what research could contribute to the design of the loss and damage fund.
The deployment length of solar radiation modification: an interplay of mitigation, net-negative emissions and climate uncertainty
Here, we investigate the deployment timescales of solar radiation modification and how they are affected by different levels of mitigation, net-negative emissions and climate uncertainty.
