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.
