Grand Solar Minimum. You should appreciate that it's starting this year since there's a great fear among some in the world about burning up in the future. It's supposed to be as bad, or worse, than the Maunder Minimum in the late 1700's and early 1600's. The Dalton Minimum wasn't even as bad and contained "the Summer that never came" in it. It would be wise to stop wasting your time and energy (no pun intended) on global warming.
