Solar cycle 24 is over 2 years late in kicking in. We haven't seen such low activity since early last century. If it continues like this, or cycle 24 is very weak (as is predicted), we could see a repeat of the Dalton minimum, or even Maunder, both of which coincided with temperature drop (little ice age). This could be a unique opportunity for modern science to further understand the effects of solar activity on climate. If we do get a repeat of these periods, we're in real trouble - much worse than a bit of warming. Do we see any preparation for this possibility?
