Other natural cycles include Milankovitch Cycles (earth's wobble), cosmic rays from the sun (sunspot activity), X Rays, UV radiation, Total Solar Irradiation (TSI), 6 sunspot cycles (7 to 600 years), Rossby waves (RW), Quasi-decadal oscillation (QSO), cloud cover, Thermohaline circulation, El Nino Southern Oscillation (ENSO), volcanic eruptions, Ekman transport, Aleutian low (AL), Interdecadal Pacific Oscillation (IPO), Kuroshio Oyashio extension (KOE), and over 20 other major climate changers.
The above doesn't include more than thirty minor cycles that are affected by TSI, just as the PDO/AMO are. Those include droughts, hurricanes, dust bowls, La Nina, El Nino, etc… It should be noted the PDO is not a single mode of temperature variability, but a conglomeration of several cycles. When each cycle peaks at the same time, one can expect abnormally high or low temperature variations, and high or low climate results.
