Most of the icy southern continent, where temperatures can plummet to minus 80 degrees Celsius (-112 degrees Fahrenheit), seemed to be holding steady or even cooling as the rest of the planet warmed. These processes are historically natural, but they’re happening much faster now, which could lead to profound impacts on the rest of the continent. of tourists are also attracted to Antarctica to enjoy the spectacular In addition to melting glaciers and ice, global warming causes early snowmelt, droughts, water shortages, and increases the risk of wildfires.
