The Climate Crisis in France: A National Emergency in the Making

France is facing a growing climate crisis marked by rising temperatures, more frequent and intense heatwaves, severe droughts, floods, and biodiversity loss, all of which are beginning to reshape the country’s environment, economy, and public health.

Rising Temperatures

Since pre-industrial times, the average temperature in France has increased by approximately 1.9°C, with projections suggesting a rise of up to 4°C by the end of the century if urgent measures are not taken. In recent years, France has experienced unprecedented heatwaves, including a historic 60-day streak of “tropical nights” where temperatures didn’t fall below 20°C. These events have stressed healthcare systems and caused higher mortality, especially among vulnerable populations.

The Water Crisis

At the same time, the 2022 European drought pushed two-thirds of France into critical alert levels, leading to an 18.5% drop in corn production and causing widespread water shortages and wildfires. Coastal regions like Languedoc Roussillon are increasingly at risk as well due to sea-level rise and erosion, threatening up to 140,000 homes. Mountain glaciers in the French Alps are retreating rapidly, with over 50% lost since 1850 and another 30–40% expected to disappear by 2050. This trend not only reduces freshwater reserves but also threatens tourism and regional ecosystems.

Biodiversity Loss

Forests, once major carbon sinks, are losing their capacity to absorb CO₂ due to prolonged droughts and heat stress carbon absorption dropped from 74 Mt CO₂ per year in 2008 to just 38 Mt CO₂ per year in 2022. Meanwhile, biodiversity in France is suffering due to habitat fragmentation and climate-driven migration of species.

The Response … or lack of

Despite these growing threats, France’s policy response remains insufficient. Although most citizens are aware of the risks 97% acknowledge climate change, and 56% support immediate adaptation the country still ranks only 25th in the Climate Change Performance Index (CCPI 2025) due to weak policy implementation in energy, transport, and land use. Experts recommend accelerating the transition to renewable energy, phasing out coal by 2027, promoting agro-ecological farming, enhancing urban green infrastructure, and decentralizing adaptation efforts to empower local governments.

A Current Crisis

France, as a global economic leader, has the resources and institutional strength to lead by example, but the time for half-measures has passed. Without swift and coordinated action, the impacts will only intensify, making recovery more difficult and costly. The climate crisis in France is no longer a distant threat it is a present-day emergency requiring bold leadership, innovation, and national unity.
