"The most famous is a period from about 1645 to 1715, called the Maunder Minimum. This period corresponds to the middle of a series of exceptionally cold winters throughout Europe known as the Little Ice Age. Scientists still debate whether decreased solar activity helped cause the Little Ice Age, or if the cold snap happen to occur around the same time as the Maunder Minimum."

It seems logical that a variable sun is going to have some affect on climate. But, I think that it will be overwhelmed by CO2 and other greenhouse gases.
