Northern ice sheet
Web20 de jan. de 2024 · A model for predicting the growth and decay of ice sheets based on the astronomical theory of climate change is presented. The purpose of the study in part is to isolate the role of the ice-sheet physics and earth response under varying ice load by simplifying to the extreme the role of the hydrosphere-atmosphere. Web24 de set. de 2024 · That’s why the Antarctic ice sheets began forming much earlier, about 34 million years ago, than those in the Arctic. While the researchers’ model doesn’t allow them to isolate the climatic effects of the rise of the Himalayas, their Southeast Asian island scenario alone can account for the appearance of Northern Hemisphere ice sheets.
