Last March, a study carried out by the French National Council for Scientific Research (CNRS) and the French Institute for Marine Research (IFREMER) was published in the journal Nature. Reporting on fifty years of research, it reveals that the structure of the Ocean is becoming increasingly stable, and that this is happening six times faster than expected. This stabilization, which is directly caused by global warming, could well challenge the Ocean's role as a natural thermostat, greatly accentuating the consequences of climate change. Here are a few explanations.
