"Avec le réchauffement climatique, l’ouest du continent nord-américain est de plus en plus souvent frappé par des événements météorologiques extrêmes, comme les vagues de chaleur, les épisodes de sécheresse et les incendies."

Les statistiques depuis 1983 ne montrent pas l'influence du réchauffement climatique que vous suspectez. Celles qui remontent aux années 1930 montrent une diminution considérable. Si la température "globale" de l'atmosphère joue un rôle, il est nécessairement mineur.
