I was thinking of something that is related, earlier today. Isn’t any warming most likely a simple matter of having a greater level of positive ENSO region conditions versus negative ENSO regions over a 30 year cyclic pattern? That is what I see when viewing the MEI long term graph.
The positive ENSO conditions move masses of moist warmth air that are then carried to other parts of the globe. Any region which gets covered by the moving warm mass builds up heat during the day, as the blanket above limits the ability to shed the daily incoming solar energy. This is how heat builds up in the system. An example of what I am seeing would be the current extra warmth being experienced in a heat wave in the Southwest over the last week or two, and still ongoing. Although the current wind pattern is shifting slightly as compared to the last several weeks. Look at the surface wind patterns which are moving from warmer regions northward into the Southwest. Those surface winds are moist and warm, and a heat wave forms…https://earth.nullschool.net/#current/wind/surface/level/overlay=temp/orthographic=-105.39,42.10,819/loc=-122.896,40.434
