The Ever-Shrinking Solar Cycle 24

Way back in March of 2007, NASA was predicting that Solar Cycle 24 would peak as early as October, 2011 with a “large cycle” estimate of a smoothed sunspot number of 140, or as late as August, 2012 for a small cycle prediction of just 90.

Now, NASA is extending/revising those numbers:

Current prediction for the next sunspot cycle maximum gives a smoothed sunspot number maximum of about 59 in June/July of 2013. We are currently two years into Cycle 24 and the predicted size continues to fall.

Via Watt’s Up With That, who has a nifty animation of the changing predictions. 

As noted before on this blog, there has been a correlation in the past with low sunspot activity and cooling climates on earth.  Is it just me, or is it getting chilly in here?
