The Guardian has the details:
Global warming in northern Europe and the eastern US could be partially offset in future winters because of the sun entering a weaker cycle similar to the one which enabled frost fairs to take place on the river Thames in the 17th and 18th century, according to new research.
However, the study said any potential weakening in solar activity would have only a small effect on temperature rises at a worldwide level, delaying the warming caused by emissions from cars, factories and power plants by around two years.
The sun has been in a period of high activity for the past few decades. But scientists believe there is now as much as a 20% chance of a weaker period of activity, known as a grand solar minimum, occurring in the next 40 years.
“Even if you do go into Maunder minimum conditions it’s not going to combat global warming, the sun’s not going to save us,” said lead author Sarah Ineson at the Met Office. The Maunder minimum is the name for the sun’s weak period during 1645-1715, when the Thames froze solidly enough for eyewitnesses to report horse-driven carriages crossing it.
Climate change means such sights in the second half of the century would not occur, since the sun’s cooling effect would only reduce manmade temperature rises in northern Europe and the eastern US by 0.4-0.8C. Such offsetting was not a “large signal”, Ineson said, although the study found there would be more frosty days in those regions than there would be without the weaker solar activity.

We are the cusp of the Next Grand Minimum, and the real issue is the impact on agriculture, and the ability to feed the worlds 6 + billions. The population was less than a billion during the Maunder Minimum, and millions starved to death. What do you think will happen when the next Grand Minimum arrives?
