That the entire lithosphere has moved cannot be denied, as the planet's climatic zones of the past are evidenced by the remains of species which are adapted to those zones, which are now found way out of those zones. An example is the multitude of Pleistocene megafauna remains currently found in a tundra environment in northern Siberia, where they could not possibly have survived, much less thrived.
What is key here is that the plants which formed the base of that ecosystem could not grow above the Arctic circle, even if it were warmer, because the land is in perpetual darkness 6 months out of the year. That situation simply could not have produced the tons of fodder for the millions of megafauna that thrived there, right up to the shores of the Arctic Ocean.
What about the "Ice Age " settlement found in Northeastern Sweden recently, where ice should have covered it completely for hundreds of miles round? Get this, mainstream proponents have proposed ther was a warm climate refugium that existed there, (and nowhere else), which was exploited by bands of humans coming into the region. Now, we are expected to believe in a magical ice-free valley?
