What it shows
This is a forward-looking scenario layer for France. It measures how often very hot days are projected to occur around the 2050 horizon, helping anticipate where heat will most threaten health, agriculture, energy systems and infrastructure.
How it is built
The layer reports the projected number of days per year with a maximum temperature reaching or exceeding 35 degrees Celsius. It is based on the French DRIAS TRACC2023 climate projection for the ~2050 horizon, at a +2°C global warming level (which corresponds to roughly +2.7°C over France). As a single-model scenario projection, it should be read as a plausible future trajectory rather than an observation. The highest values fall in the Rhône valley, Provence and Languedoc.
How to read it
Higher counts mean more extreme-heat days per year are projected, indicating greater exposure to heat-related health risks, agricultural stress, cooling-energy demand and infrastructure degradation. Lower counts indicate fewer such days.

Comparison with the WWF Risk Filter Suite
The WWF Risk Filter Suite publishes present-day, global indicators only. This is a France-specific, forward-looking 2050 projection of extreme-heat risk, so it has no distinct equivalent in the WWF methodology. It serves as a national, scenario-based complement to WWF's present-day extreme-heat indicator (S3_5).
