Something odd going on?

Here's a rather alarming chart, it shows the average surface temperature for the North Atlantic over many years (all the blue lines), the red line is this year, 2023. Clearly there's something odd going on, and although the absolute temperature rise isn't huge (i.e. less than 1 degree) in the aggregate that's huge, the surface of the ocean (i.e. the first meter or two) contains more energy that the entire atmosphere. If this is correct then it could lead to many more violent storm events and extremes of temperature, much like we saw last year when we topped 40 degrees in the UK for the first time in (metrological) recorded history.
