L’\u00e9volution des temp\u00e9ratures annuelles constitue l’un des meilleurs indicateurs du changement climatique en France. Gr\u00e2ce aux observations r\u00e9alis\u00e9es depuis 1900, il est possible de mesurer les \u00e9carts \u00e0 la moyenne des temp\u00e9ratures d’une ann\u00e9e \u00e0 l’autre et de mettre en \u00e9vidence une tendance nette au r\u00e9chauffement. Les anomalies annuelles montrent que les ann\u00e9es les plus chaudes se concentrent d\u00e9sormais au cours des derni\u00e8res d\u00e9cennies.<\/p>\n
