QUE SIGNIFIE GLOBAL DIMMING EN ANGLAIS
Graduation globale
La gradation globale est la réduction progressive de la quantité d'irradiation directe mondiale sur la surface de la Terre qui a été observée pendant plusieurs décennies après le début des mesures systématiques dans les années 1950. L'effet varie selon l'emplacement, mais dans le monde entier, il a été estimé à l'ordre de 4% de réduction sur les trois décennies de 1960 à 1990. Cependant, après avoir actualisé une anomalie causée par l'éruption du mont Pinatubo en 1991, un léger renversement de la tendance générale a été observé. On pense que la gradation globale a été causée par une augmentation des particules telles que les aérosols de sulfate dans l'atmosphère en raison de l'action humaine. Cela a entravé le cycle hydrologique en réduisant l'évaporation et pouvant réduire la pluviométrie dans certaines régions. La gradation globale crée également un effet de refroidissement qui a peut-être contrebalancé partiellement l'effet des gaz à effet de serre sur le réchauffement climatique.
définition de global dimming dans le dictionnaire anglais
La définition de la gradation globale dans le dictionnaire est une diminution de la quantité de lumière solaire atteignant la surface de la terre, que l'on croit être causée par la pollution de l'atmosphère.
