I believe the work of the famous Danish solar scientist, Professor Henrik Svensmark, in his seminal book, The Chilling Stars: A New Theory of Climate, wrote of this.
He basically stated the lessening of the solar wind would mean more cosmic radiation reaching Earth, and thus causing cloud formation, which then enhances albedo, and less warmth from the Sun to the Earth.

Excellent book!
