Publication: Key figures on climate change in Brittany – 2025 edition
Climate: a new publication raises the alarm about Brittany’s future at +4°C
In May 2025, the Observatoire de l’Environnement en Bretagne (OEB) published a new edition of its brochure ‘Key figures on climate change in Brittany’, a reference document highlighting the expected effects of climate change in the region by 2100. This is the first regional publication in France to be based on the reference trajectory for adaptation to climate change (TRACC) set by the French government.
The report paints an alarming picture: rising temperatures, more intense droughts, increased risk of flooding and more frequent extreme weather events. Clear data, remarkably presented through extensive data visualisation in the form of maps, graphs and infographics, is made available to help elected officials, local authorities, businesses and citizens better understand the challenges ahead.
This work draws on extensive scientific expertise and was carried out with significant contributions from researchers and engineers from the European Institute for Marine Studies (IUEM). Among them, Anne-Marie Tréguier, Guillaume Charria, Alain Hénaff and Peggy Rimmelin Maury participated in the analysis and drafting of this brochure, particularly on coastal and maritime phenomena.
The publication is accompanied by a summary poster entitled ‘Brittany in a France at +4°C’ and a regularly updated web version. Available in all libraries, media libraries and secondary schools in the region, it embodies a desire to make scientific information accessible to all.
