Les cristaux de glace renferment de minuscules bulles d'air qui témoignent de la composition passée
Les cristaux de glace renferment de minuscules bulles d'air qui témoignent de la composition passée de l'atmosphère en gaz carbonique et en méthane. L'étude de l'évolution de la concentration de ces gaz sur des carottes glacières permet de déduire les variations climatiques passées.
