With global warming, “immune” regions will be affected by

With global warming, fires are expected to affect regions hitherto immunized against these natural disasters and whose vegetation is less able to regenerate than in the Mediterranean areas, noted French researchers on Tuesday 28 June.

What we see in our research is that global warming has three consequences, the first is a spatial extension of the risk zone, with contamination of regions that were historically immuneagainst fires, underlined Renaud Barbero, climatologist researcher at the National Research Institute for Agriculture, Food and the Environment (Inrae), during a press briefing.

Projections based on analyzes by UN climate experts (IPCC) show that the risk zone will extend towards the north of Europe, and then in altitudefor his part noted Jean-Luc Dupuy who studies the spread of fires and their evolution in Europe at the Inrae research laboratory in Avignon.

Increase expected in Pays de la Loire and Center

Today, the area burned each year in Europe is on average 400,000 to 500,000 hectares, mainly in the Mediterranean countries (Spain, Greece, Italy, France etc.), which have long been accustomed to these fires during the summer. .

In France, the activity (fires) will intensify in the areas where it is already strong, in the South-East and also extend to the mountainous margins of this southern regionwhere temperatures and drought will increase, gave Jean-Luc Dupuy as an example.

The weather danger will also increase in the northern half, particularly in the Pays de la Loire and the Center where we will see a significant increase in fires in the future, according to our projections.he added.

In the United States, where burned areas have increased by 1,200% over the past three to four decades, fires are also occurring more in high altitude areas, which were hitherto spared, noted Renaud Barbero.
