Melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of sea level rise, new satellite research shows. At the current rate, the world's oceans on average will be at least 2 feet -- 61 centimeters -- higher by the end of the century compared to today. Also this has a great impact on the animals such as penguins and polar bears. The ice melts so the animals die. This can also cause greats tsunamis and flood.
