Quelque infos qui expliquent ce phénomène :

The effects are greatest in winter in each hemisphere. There is good but incomplete evidence that changes in winds alter ocean currents, ocean convection and overturning, resulting in changes in the amount of heat sequestered deep in the ocean during the negative phase of the Pacific Decadal Oscillation.

Research shows that ocean heat content increases more steadily than surface air warming and is a better metric to show that global warming continues.

C’est clairement inquiétant. Je m’y connais pas mais je doute que ça va revenir à ce qui était observé les années prédentes vu la différence qu’il y a.
