In a recent statement, G7 foreign ministers acknowledged the urgent need to “scale up climate finance for adaptation in line with the Glasgow call to at least double the collective provision of adaptation finance from 2019 levels by 2025, in the context of achieving a balance between mitigation and adaptation in the provision of scaled-up financial resources, recalling Article 9, paragraph 4, of the Paris Agreement“.
It has been estimated that adaptation finance was roughly USD 20 billion per year in 2019. A doubling of efforts, as agreed in the Glasgow Climate Pact and reiterated by the G7 ministers, would bring adaptation finance into the vicinity of $40 billion.
At this rate we would fall woefully short of what the latest science from the IPCC and the 2021 Adaptation Gap Report tell us will be needed (Figure 1). Median values for cost estimates stand at USD 127 billion in 2030 and USD 295 billion in 2050. This may sound prohibitively large, but in comparison fossil fuel subsidies stood at USD 440 billion in 2021.
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.
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.
