Une étude de la NASA confirme que les eaux profondes se sont réchauffées.
Les auteurs concluent que le refroidissement relatif des eaux superficielles (moins de 100 m de profondeur) est compensé par un réchauffement des eaux profondes (100 à 300 m) dans Océan Indien et l´Océan Pacifique.

Recent modeling studies have proposed different scenarios to explain the slowdown in surface temperature in the most recent decade. Some of these studies seem to support the idea of internal variability and/or rearrangement of heat between the surface and the ocean interior. Others suggest that radiative forcing might also play a role. Our examination of observational data over the past two decades shows some significant differences compared to model results from reanalyses, and provides the most definitive explanation of how the heat was redistributed. We find that cooling in the top 100-meter layer of the Pacific Ocean was mainly compensated by warming in the 100- to 300-meter layer of the Indian and Pacific Oceans in the past decade since 2003.
