When you think of the Ice Age, do you think of elephants on a clear day near icy morasses in the snowy north like in the animated movie? Think again, frozen buttercups, ferns, trees, and grasses are entombed in the tundra with the mammoth carcasses along the Arctic ocean, so that region was green with pastures and forests during the Ice Age, and clearly, lots of cloudy days with lots of rainfall.
Why was there rainfall in the frozen north now considered a desert for lack of precipitaion? The key is the cloudcover, lots of it during the Ice Age, not what people think much about, but consider all the snow which need have fallen to have covered some portions of continents with two miles deep of snow and ice?
During the Ice Age it was cloudy virtually all the time, with snow falling in the exteme latitudes and high elevations, and rainfall where now are deserts in the middle latitudes as well as near the coastlines even in the far north where the coastal regions were pastures and forests during the Ice Age, because the nearby world ocean was much warmer, see more http://genesisveracityfoundation.com.
