régions méditerranéenne et atlantique
Avec une hausse de la température moyenne de la planète de 3 °C, les sécheresses seraient deux fois plus fréquentes et les pertes annuelles en valeur absolue liées aux sécheresses en Europe augmenteraient pour atteindre 40 milliards d’euros par an, les conséquences les plus graves touchant les <anchor>régions méditerranéenne et atlantique</anchor>. Si les sécheresses se font plus fréquentes et plus graves, la durée et la gravité de la saison des incendies augmenteront, en particulier dans la région méditerranéenne. Le changement climatique élargit également la zone exposée aux risques d'incendie. Des régions qui ne sont pas actuellement exposées aux incendies pourraient devenir des zones à risque.

## Summary of Key Findings

With global warming, droughts will become more frequent, last longer and become more intense in Mediterranean and Atlantic regions of Europe.

Drought conditions will become less extreme in Boreal and Continental Europe. Total economic losses from drought in Europe would grow from 9.4 €billion/year now to 45 €billion/year with 3°C global warming in 2100.

Under the climate change mitigation scenarios considered in PESEAT IV, the damage in 2100 would be approximately halved compared to no mitigation.
