Solar Minima, Earth's rotation and Little Ice Ages in the past and in the future: The North Atlantic–European case

The past Solar Minima were linked to a general speeding up of the Earth's rate of rotation. This affected the surface currents and southward penetration of Arctic water in the North Atlantic causing “Little Ice Ages” over northwestern Europe. At around 2040–2050 we will be in a new major Solar Minimum. It is to be expected that we will then have a new “Little Ice Age” over the Arctic and NW Europe. The mechanism proposed for the linkage of Solar activity with Earth's rotation is the interaction of Solar Wind with the Earth's magnetosphere; the decrease in Solar Wind at sunspot minima weakens the interaction with the magnetosphere that allows the Earth to speed up, and the increase in Solar Wind at sunspot maxima strengthens the interaction with the magnetosphere that slows down the spinning of the Earth.
