    1. The “tradition” in some places is to use the last 30 year period ending on a 0 year.

      The CRU/Met still use 1961-1990 for most of their indexes.

      Cryosphere use 1979-2008 for some reason …

      The WMO says 30 years is climate.

      1. Thanks for that. I was just thinking that 2012 would lower the avg and then 2013 would be avg or posibly above,
