Enjoyed this update tremendously; however the latest May tropical Pacific surface temperature begs the question: Are we on the edge of witnessing a 4th year of La Niña?   If so, is there a chance a new weather system is emerging (i.e. longer La Niñas) due to other not-so-obviously related climate variables?  The melting Greenland ice sheet cooling the Atlantic (for the time being...) comes to mind.

This ongoing La Niña seems so strange.  The Walker circulation's increasing cooling ability - when most other natural systems seem to be trending towards more heat - seems odd from a lay perspective.  Would love it if this natural phenomenon could be unpacked more!
