Researchers studying the Barnes Ice Cap in the Canadian Arctic determined that the remnants of the massive Laurentide Ice Sheet grew for centuries before reaching their greatest extent around 1960. However, human-caused greenhouse warming and modern climate change reversed this natural expansion, effectively halting the start of another ice age.Why it mattersThe Laurentide Ice Sheet once buried nearly 30 percent of North America during the Pleistocen
