IRISCC in France: Research Tools for the Climate Crisis

Europe is the world’s fastest-warming continent and is currently enduring its hottest summer on record (Copernicus C3S, 2026). France is at the center of this crisis, facing a spiral of severe environmental challenges. Scorching temperatures and persistent droughts have depleted major rivers and recently placed many areas at high risk for forest fires. Following destructive blazes across the Gironde, Var, and Drôme regions, the compounding nature of these climate risks is threatening both local landscapes and regional air quality.

To address these climate risks, researchers need access to robust environmental research infrastructures. IRISCC is building a bridge between these existing facilities and the critical need for actionable solutions in climate change risk research. Our goal is to encourage researchers and decision-makers to explore the facilities that are relevant to these ongoing climate risks and apply for access.

The following research facilities are available in France to support research into these critical environmental threats:

Puéchabon

To combat severe drought, heat stress, and forest vulnerability, Puéchabon conducts long-term rainfall exclusion (-30% precipitation) and soil warming experiments (+2°C). This Mediterranean evergreen forest site monitors carbon and water balances during intense dry spells, providing vital data on how woodland ecosystems survive prolonged heat.

SIRTA

Located in Île-de-France, this Atmospheric Research Observatory studies physico-chemical processes from the surface up to the upper troposphere. It provides vital, multi-decadal observations of reactive gases, greenhouse gases, and aerosols to evaluate atmospheric models and track regional climate variability and radiative exchanges.

CESAM_CNRS

This platform consists of two atmospheric simulation chambers designed to investigate atmospheric processes under controlled and realistic conditions. The CESAM chamber specifically focuses on multiphase atmospheric processes, such as the formation of secondary aerosols and cloud-phase reactivity, which is vital for understanding the broader atmospheric impact of wildfire smoke and pollutants. This platform is situated in Créteil.

FOREST-O3HP Platform

Located at the Observatory of the Upper-Provence, this in natura field site is dedicated to understanding the response of deciduous Mediterranean forest ecosystems to climate change. To aid in drought research, the site is equipped with a precipitation exclusion system that dynamically excludes 30% to 40% of rainfall to simulate the drier climates predicted for the end of the century.

Jardin du Lautaret

This facility is dedicated to alpine environmental research. It provides experimental zones, greenhouses, and climatic chambers to study how living organisms and ecosystems adapt to climate warming, severe droughts, and changes in the cryosphere/snow levels. It is spread across two sites, including an alpine station located at 2,100 meters.

Take Action Now
