Certainly greater solar output causes global warming, while any manmade causation is doubtful at best, yet either way, warming of the atmosphere heats the surface of the ocean to cause more evaporation for more cloud cover providing shade and cooling rainfall (snowfall at higher elevations), so considering this negative feedback mechanism in the hydrologic cycle, it’s obvious that the dense cloud cover for the Ice Age must have been by the ocean warmer (by the fountains of the deep) in the aftermath of Noah’s Flood, an inconvenient truth for the myopic uniformitarians.
