Why is the Arctic Asymmetric? | Why Trees Grow at the Same Latitude as Ice Sheets

In this video we explore the geography of the Arctic. Why do trees grow at the same latitude as ice sheets? Why is the Hudson Bay the southernmost place to find polar bears? Why is Greenland covered in ice, but not Alaska or northern Siberia? Despite hundreds of faulty maps illustrating two symmetric "ice caps" at the poles, reality is far more complicated and interesting. To understand the ecology and climate of the north, we need to consider one underestimated aspect of climate. Sources: Impacts of Hudson Bay on the Terrestrial Climate of the Hudson Bay Lowlands.
