Scientists characterize Earth rotation velocity using a variable they call length of day (LOD). The rate of change of LOD (LOD’) is related to global average wind patterns. Changes in wind patterns affect temperature patterns.
See the graphic below.
Could it be that apparent relationships between the rate of change of solar cycle length (SCL’), LOD’, & North Atlantic Ocean sea surface temperature (AMO = Atlantic Multidecadal Oscillation) are independent?
UPDATE: Paul asked me to add these two graphs, he writes:
Notes on notation:
GLAAM = global atmospheric angular momentum
NOR = nutation in obliquity residual
 indicates time-integration
SOI = Southern Oscillation Index
f(x) on the SOI, GLAAM, LOD graph indicates a filter that isolates interannual features. This result has been known to scientists for decades, so my SOI, GLAAM, LOD graph is simply a sample of what I discovered last year when I audited their claims using my own approaches. (If anyone wants the literature references, please feel welcome to request them and I’ll dig them out.)
