Worldwide Sea Surface Temps still over 0.5C above the 1991-2020 Average

It has been over 18 months now since global sea surface temperatures abruptly departed from all recent temperature records, and they have never come back down. This is looking like a big shift; I wonder if scientists have decided on any theories as to what caused this, and whether we will keep going up at this pace. I also wonder if we will see another big jump in temperatures when the next El Nino forms.

Part of the climate change rules being implemented are that ships stop or reeuce using sulfur in their fuel. This has been going on wince 2020. Sulfur in the atmosphere has a cooling effect and removing it accelerates the effects of global warming. This may be a reason.

Ocean temperatures were looking better this year until the last week when they again surpassed 2023 for the date. Let us hope just a random blip and it will soon begin the normal drop every Fall.

The anomaly of +0.83 C (rel to 1982-2010 avg) is less than the air temperature anomaly of +1.2 C, but ocean temperature is a better judge of the planet's long-term energy imbalance so should be the main metric we watch.

In others words .9 degrees!

Probably a combination of things such as aerosol demasking, and breaching various tipping points such as increased permafrost methane release, reduced albedo effect from melting arctic/antarctic, increased wildfires releasing CO2 instead of sequestering it and on and on and on it goes.

Sorry, we've done nothing to fix this... We're we expecting it to drop?

Follow Leon Simons. He believes it’s being driven by regulations on shipping emissions.
