La tendance de la superficie de glace de mer pluriannuelle en septembre est calculée sur la base de la superficie moyenne de la glace de mer pluriannuelle au cours du mois de septembre pour chaque année de 1968 à 2024. Il est fait état d'une tendance statistiquement significative lorsque le test de Mann-Kendall indique la présence d'une tendance à un niveau de confiance de 95 %.,,,,,,, Source : Environnement et Changement climatique Canada (2024) Direction de la recherche climatique.,,,,,,, Disponible sur le site Web des Indicateurs environnementaux (www.canada.ca/indicateurs-environnementaux).,,,,,,, ,,,,,,, ,,,,,,, ,,,,,,, ,,,,,,, ,,,,,,, ,,,,,,, ,,,,,,,
