Multi‐Stability of the Present‐Day Atlantic Meridional Overturning Circulation There is much supporting evidence (freshwater export, paleo records, model hierarchy) that the present-day AMOC is in a multi-stable regime.

Breaking: A new review paper of the tipping point risk of the Atlantic ocean circulation system known as #AMOC has been published. 🌊
The evidence has broadened over the last years that the present AMOC is in a multi-stable regime, posing a risk of tipping 😨.

The Mediterranean Sea is home to some of the ocean’s largest animals. Among the nine species of #cetaceans are the fin #whale (Balaenoptera physalus, the world’s second-largest marine animal), and the sperm #whale (Physeter macrocephalus). theconversation.com/whales-leave...
