NASA: Much has been made of the probable connection between the Maunder Minimum, a 70-year deficit of sunspots in the late 17th-early 18th century, and the coldest part of the Little Ice Age, during which Europe and North America were subjected to bitterly cold winters. The mechanism for that regional cooling could have been a drop in the sunâs EUV output.
Indeed, the sun could be on the threshold of a mini-Maunder event right now. Ongoing Solar Cycle 24 is the weakest in more than 50 years. Moreover, there is (controversial) evidence of a long-term weakening trend in the magnetic field strength of sunspots. Matt Penn and William Livingston of the National Solar Observatory predict that by the time Solar Cycle 25 arrives, magnetic fields on the sun will be so weak that few if any sunspots will be formed. Independent lines of research involving helioseismology and surface polar fields tend to support their conclusion.

NSO: It was announced at the recent annual meeting of the Solar Physics Division of the American Astronomical Society (AAS/SPD) at New Mexico State University that the next 11-year solar sunspot cycle, Cycle 25, will be greatly reduced or will not occur at all. Magnetic fields erupting from the sun will be so weak that few if any sunspots will form. The current sunspot cycle, Cycle 24, started out late and slow and will likely produce a very weak solar maximum in 2013.
This report from the National Solar Observatory (NSO) and the Air Force Research Laboratory at Kitt Peak in Arizona indicates that the familiar sunspot cycle may be shutting down for a while, causing global cooling.
