Regional climate change

Hypothesis: It is impossible to address regional climate change without fully addressing how patterns of climate variability (modes) change, and thus how:
ENSO: El Ni–o Southern Oscillation
NAO/NAM: North Atlantic Oscillation/Northern Annular Mode
SAM: Southern Annular Mode
PDO: Pacific Decadal Oscillation
AMO: Atlantic Multidecadal Oscillation
change!
