Are we headed for a new extended sunspot minimum?

    In a plot of sunspots since Galileo first observed them, two periods warrant attention, the Maunder minimum between 1645 and 1700 and the Dalton minimum between 1798 and 1830 coincided with global temperature reductions of about 0.3-0.5 deg C.

    The last solar cycle was a long one, and ended with a deep trough:

    Clearly deep lows are often followed by small cycles. Some say long cycles precede small cycles, but the correlation with previous smoothed low is better. We can model this and then predict the smoothed peak of the cycle 24:

    Furthermore, sunspots are becoming less magnetic. So, are we headed for an extended low period?
