“Global warming is reducing the amount of food for penguins so that they can’t find enough to eat，” scientist Shaye Wolf said.
Turning up the heat
Humans may be directly responsible for the continent’s temperature changes, according to a new study in the journal Nature Geoscience.Temperatures in Antarctica usually do not go above freezing, or 32 degrees Fahrenheit.
返回
Scientists are concerned about the possibility that
Antarctica’s ice may melt more over time. The icy continent is about 5 million square miles. It is covered by glaciers and an ice cap(冰冠)about 7,100 feet thick. If the ice melts, that could cause sea levels to rise around the world. Higher sea levels could lead to dangerous flooding in some countries.
