Environment and homeland security in France

The author comments the impact of extreme events related to global warming and climate change on the French homeland security. He comments the evolution of temperature during the last century, the various transformations notably predicted by IPCC reports, and the various climate evolutions. Then, he discusses impacts of climate change on different economic sectors. He notably addresses the impact on coast lines (risks of submersion and erosion, more particularly for overseas territories), the impact extreme events may have on soft water (a temperature rise would impact the operation of nuclear plants; sewage and water networks will be threatened by more intense rainfalls), the positive and negative impacts on forests (high productivity but loss of diversity, development of parasites, risks of forest fires), and the impacts on various economic activities (agriculture, food supply, tourism, insurance) and on health
