This is a tremendous series of articles. I am extremely grateful to have found them. I am reading through each one, up to this point so far, and have benefitted tremendously by your work. It would be worth it for me to join this platform just to pay you for your efforts herein! Continuing on, what still bothers me is whether Howorth was right that ice ccannot do what it is said to have done: can an ice sheet exhibit significant basal flow, flow uphill, or move at all over hundreds of miles? Is Greenland or the Antarctic providing evidence that real, physical ice can do this, or is the ice of the Ice Age a theoretical non-physical ice?
