Better understanding local climate change and helping territories to adapt.
How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
European climate variability is shaped by atmospheric dynamics over the North Atlantic and local processes. Better understanding their future seasonality is essential to anticipate changes in weather conditions for human and natural systems. We explore atmospheric seasonality over 1979–2017 and 1979–2,100 with seasonal circulation regimes (SCRs), b...
Climate change has various impacts on society, but future changes are uncertain and a wide gap remains between the scientific knowledge and societal action (mitigation, adaptation). The gap in climate adaptation was partly addressed by the recent growth of climate services, but their local usability is associated to many barriers. France is an exam...
We developed, tested and refined a novel incremental participatory scenario approach. This method allows for the development of normative scenarios, pathways that lead to desirable futures, with local communities, through a non-linear approach. Developments in the real world rarely follow straightforward linear paths. The approach inventories ‘hing...
We investigate North Atlantic weather seasonality over 1979–2100 by classifying year-round fields of 500 hPa geopotential height from one reanalysis dataset and 12 climate models. Generally, models have seasonal structures similar to the reanalyses. Historical winter (summer) conditions decrease (increase), due to uniform Z500 increase (i.e. unifor...
In France, integrating adaptation to climate change into planning policies is a prerogative that has recently been delegated to municipalities. There are also various injunctions to engage the local population in this decision-making process. How can municipalities co-construct an adaptive future with their citizens? This article critically describ...
In this report, local climate service components are evaluated. In CoCliServ, local climate service components are 1) local narratives (input from WP1) and 2) existing climate information and services (assessed in task 3.1.). For each case study site, local narratives of change are evaluated according to potential entry points for local contextuali...
We explored different issues and trends at play in the case study areas that might be relevant for designing local scenarios. Particularly, we examined both climate-related and non-climate related aspects, and aspects that the local community has considerable influence on as well as those that are largely beyond their control. These different aspec...
CoCliServ explores novel ways to transform climate science into action-oriented place-based climate services to engage, enable and empower local communities, knowledge brokers and scientists to act locally. It seeks to identify future information needs and the nature of the climate science needed to address the local communities’ concerns, aspirations and goals in view of climate variability and climate change.
