You don’t have to be a rocket scientist to understand that clouds come off the ocean by evaporation, the warmer the ocean, the greater the evaporation, the engine for the Ice Age the ocean warmer in the aftermath of Noah’s Flood, so Christians saying they believe Genesis without good reason (other than that the Word says it), ignoring logic such as the cause of the Ice Age, are probably sinning by omission, unless the person is incapable of simple intellectual exercises, for instance too that the Ice Age ended because the skies cleared for warmer summers and colder winters.
