A recent, rapid heating of the world's oceans has alarmed scientists
concerned that it will add to global warming.
This month, the global sea surface hit a new record high temperature. It
has never warmed this much, this quickly.
Scientists don't fully understand why this has happened.
But they worry that, combined with other weather events, the world's
temperature could reach a concerning new level by the end of next year.
Experts believe that a strong El Niño weather event - a weather system
that heats the ocean - will also set in over the next months. ...

The greater part of this warming has been in the tropical Indo-Pacific. This of course includes the equatorial Pacific where El Niño warming is underway but there seems to be an inter-basin coupling across the Indian Ocean, which has also shown significant warming. Mid-latitude SSTs have seen mixed changes.

From an NOC expert on the North Atlantic, no proven teleconnection
between Pacific ocean oscillations and Atlantic AMOC or NAO, despite the
proven jetstram teleconnection.
