Here is one paper on the current solar cycle 24 (from 2010):
The incipient cycle 24 will probably mark the end of the Modern Maximum, with the Sun switching to a state of less strong activity. It will therefore be an important testbed for cycle prediction methods and, by inference, for our understanding of the solar dynamo.
How have predictions for a weak solar cycle been panning out?
The current predicted and observed size makes this the smallest sunspot cycle since Cycle 14 which had a maximum of 64.2 in February of 1906.This solar cycle is shaping up to be even less active than the 1970s.
This is a picture of days above freezing at the Artic circle this year. Green is the average, red line is this year.
