|Atlantic Multi-Decadal Oscillation|
Definition: (Aka AMO) A multi-decadal (e.g., 65 to 75 year) fluctuation in the North Atlantic during which sea surface temperatures showed:
(1) warm phases during (roughly) 1860-1880 and 1930-1960 and
(2) cool phases during 1905-1925 and 1970-1990 with a range of order 0.4°C.
1. According to Michael Mann, the term was coined by Michael Mann:
"I coined the term in an interview with Richard Kerr [a writer for Science] in 2000 about a paper he did with Tom Delworth of the GFDL and the NOAA Laboratory in Princeton, where we actually were the ones to articulate the existence of this oscillation. And you know what? It was celebrated by contrarians. My work has been celebrated by climate skeptics. It's an interesting footnote."
