Here is an interesting diagram. Solar Cycle 24, which ended on July 17, 2014, was one of the deepest solar minimums in 100 years. Notice that Solar Cycle 24 can be said to be part of the 100 year lowest solar maximum cycles as shown during the solar minimums of 1824, 1878, 1915, and 2008. Will Solar Cycle 25 be lower than Solar Cycle 24? Only time will tell.

Notice the 1878 to 1915 period of time in which we had a succession of very deep solar minimums.
By this graph from SILSO in Belgium, Al Gore is once again proven wrong. We have just come out of a warming solar maximum in 2006 with hot summers during the solar maximum of 2001. Solar Cycle 24 did not deliver much of solar impact. It was very mild in comparison to Solar Cycle 19 in in 1958 and 1959, where I vividly remember being sunburned at Lake Tahoe and at other swimming holes in Nevada while I was in my pre-teen years. The elevation of +5000 feet did not help because higher elevations receive higher solar radiations. In fact, SC 19 has been the highest in 200 years.
The data is not in for the Solar Cycles during the 1700s. SILSO must do some "corrections" before that data can be presented. Some scientists have said that we could be entering an even lower solar minimum during this Solar Cycle 25, per the very low 300 year cycle. From 1646 to 1715, we had the Minimum Maunder, a mini-ice age where it was so cold that people could ice skate on the River Thames in London. Could Solar Cycle 25 be a non-event, one that plunges us into another Minimum Maunder? Or will Solar Cycle 26 be the one where the sun seems to go dormant? Again only time will tell.
There are several articles that discuss this matter more in detail. Even Scientific America had their say.
