More 4 ° C. It is the scenario of global warming that chose to highlight the Minister of Ecological Transition and Territorial Cohesion, Christophe Béchu, to present the first “ministerial steering committee on adaptation to climate change”, which was held Thursday, February 23. “Preparing our country at 4 ° C, that means anticipating many changes, said Christophe Béchu, the day before on Franceinfo. At 4 ° C, two thirds of ski resorts will lack snow in the Alps, (…) We will have five times more drought, (…) much more intense heat wave. “
To initiate reflection, the Minister therefore brought together the central directions of his ministry, whose energy and climate, that of risk prevention, but also the agencies and operators concerned by climate work, Météo France, the Environment and Energy Management Agency, the Center for Studies and Expertise on Risks, the Environment, Mobility and Planning, the National Geographic Institute.
On the table, two trajectories for which it is essential to prepare the country, dictated by the forecasts of the group of intergovernmental experts on the evolution of the climate (IPCC) in its last report: warming at 2 ° C or 4 ° C (compared to the pre -industrial era) for France, which would mean, in the first case, respect for the objective of the Paris Agreement and, in the second, its surpassing in a context of ” unchanged policy “. In fact, these 4 ° C for France correspond to the global average of 3 ° C of warming in one of the scenarios of the IPCC. Knowing that the increase in the planetary thermometer already reaches 1.2 ° C, and 1.7 ° C for France.
Build a new strategy
This strategy should make it possible to “harmonize all public adaptation policies in order to prevent environmental, social and economic risks incurred in each territory”, it is said to the ministry. The two scenarios studied must be put in consultation in the spring and will serve as the basis for the development of the third national plan to adapt to climate change (PNACC), expected at the latest in 2024. This work on adaptation is not new. From 2018, the first PNACC was adopted, followed seven years later by a second.
Without giving up attenuation policies which aim to reduce greenhouse gas emissions, already at work in public policies, according to the Minister, the challenge is to build a new strategy. This first meeting of the steering committee worked on the basis of a report by the General Inspectorate of the Environment and Sustainable Development (IGEDD) delivered this Thursday, mainly aimed at comparing adaptation strategies in eight countries (Germany , Austria, Canada, Spain, Japan, Netherlands, United Kingdom and Switzerland). In this report, commissioned by the Minister of Ecological Transition Barbara Pompili in April 2022, the inspectors write to have “identified methods common to most of the countries studied, as well as the good practices by which some of them are distinguished”.
