The winter of 2011-2012 (Dec, Jan, Feb) for the northern hemisphere was the 13th warmest since 1880, but 4th coldest since 2000, according to the Goddard Institute for Space Studies.These are observed temperature/ocean surface measurements.
During this past winter in the Northern Hemisphere the average temperature was 0.58 C above normal.

Globally, the Dec, Jan, Feb period was the 14th warmest since 1880 and the 4th coolest since 2000. The temperature anomaly was 0.40 C above normal, according to the GISS data.
The GISS image below shows the global temperature anomalies for the Dec 2011 - Feb 2012 period.

How did February 2012 rank?
February 2012 ended up tied for 16th warmest February on record globally going back to 1880, but tied for 2nd coolest February since 2000, which tells you how warm this past decade has been.
The GISS image below shows the global temperature anomalies for February 2012.
The GISS chart below clearly shows that the highest temperature anomalies for February 2012 were north of 60 degrees north latitude, which has been the case for quite a while, but not so dramatic as this.
