Muller & his Berkeley team’s analysis: Global temp correlates more closely with the state of the Atlantic Multidecadal Oscillation (AMO) index – a measure of sea surface temps in the N. Atlantic’
'The team suggests it is worth investigating whether the long-term AMO cycles, which are thought to last 65-70 years, may play a part in the temperature rise, fall and rise again seen during the 20th Century'
Muller: 'Had we found no global warming, then that would have ruled out AGW'
