And, for the umpteenth time, you have YET to identify what caused that glaciation. Plate tectonics didn't do it. The sun didn't do it. The atmosphere didn't do it. Ocean currents didn't do it.It does if the region is close to the temperature threshold for glaciation and its landmass configuration is such that extensive continental glaciation can spread. There have been over 30 such events in the last 3 million years and each and every one of them happened because the Arctic glaciated and those glaciers spread to the surrounding continents of NA, Europe and Asia.
How can you be so unimaginably stupid about this?
Another Ding mistake.
