The difference between 2012 and 2013 is quite dramatic if you graph the anomaly % from the 30 year mean.
Until day 175 or so, the anomaly was only around -5% or so (note that the anomaly actually went positive for a few days in 2012).
While 2013 was later, both started drifting down. 2013 has stabilized at -15%. At this time last year 2012 was -30%.
Warmists must be so sad.

Yes. I’m a firm believer that ocean cycles like the AMO have more to do with the ice than air temperatures. But winter month AMO temps have been dropping too so it could be a bad combo.
