The trend of milder winters in France, linked to climate change, poses significant ecological and agricultural challenges. Scientific reports indicate a reduction in freezing days, which threatens natural pest control and affects the production of various crops. Regions like Grand Est and Hauts-de-France are notably impacted, with rising temperatures altering traditional farming practices and necessitating adjustments in agricultural strategies to cope with the changes. The warming climate may also lead to increased weed growth and a burgeoning market for allergy treatments.
