Notice that in solar cycles 21 and 22, the solar flare index was closely in sync with the other indicators, but in solar cycle 23 (1995-2009) started diverging. This might be connected to what Livingston and Penn are talking about.
If the solar trend continues down into 2013, and the winter of 2012-14 is unusually cold, it may be time to start worrying.
