Rather worrying find.

Typically, as global heating melts the ice around Antarctica, climate scientists would expect saltier water at the surface of the ocean to be replaced by fresh water, because melting ice typically makes the ocean fresher.

But new satellite data shows the opposite is happening.

Climate System teleconnection ... climate tipping elements linked with the potential predictability of cascading tipping dynamics. It seems what happens in the Amazon (Deforestation), doesn't stay in the Amazon.
