This study examines the effects of expanded irrigation on climate conditions around the world, specifically in comparison to other anthropogenic forces. It finds that irrigation can regionally cancel the effects of these anthropogenic forces in the face of increasing temperatures from global warming.
The study further finds that approximately one billion people currently benefit from irrigation’s ability to dampen the increase of hot extremes, though it is uncertain whether this benefit will continue in the future.
Here we provide observational and model evidence that expanding irrigation has dampened historical anthropogenic warming during hot days, with particularly strong effects over South Asia.
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.
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.
Emissions as usual: implications for the Safeguard Mechanism of LNG and coal mine projects
This report examines the implications of committed and proposed developments in the LNG and coal mining sectors for reform of Australia's Safeguard Mechanism.
