The 1990s weren't anything special. I'm not sure why you keep coming out with this. Sure the last few years has been a poor run, but on average here:
Winter Index:
1990s: 57.0
2000s: 48.3
2010s: 68.9
Days of sleet/snow falling:
1990s: 11.8
2000s: 11.9
2010s: 11.7
Days of Snow lying at 0900:
1990s: 5.8
2000s: 3.6
2010s: 7.6
Winter months more than 1C below average:
1990s: 2
2000s: 2
2010s: 5
Winter mean temp:
1990s: 4.77C
2000s: 5.08C
2010s: 4.69C
The 2010s are almost unanimously better, despite the last few years being poor. Sure, 2010-2013 heavily weigh up the 2010s, but 1991, 1996 and 1997 did the same in the 1990s.
