The effect of climate on glaciers?

Let me give you one example. Now, if the glaciers can melt, then in the polar regions it will become much warmer. That is, the climate will change in this way. And on Antarctica, freed from the ice, vegetation can appear, and new animals will also begin to live here. This is exactly how it was in the Neogonic period, which was on our planet several million years ago. There were no glaciers then and the climate was much milder.
