Walruses use sea ice as platforms on which to nurse their young and launch their dives for clams and other bottom-dwellers. Each spring, walruses move northward to stay close to these perches as ice...
Drilling near the North Pole, Dr. Jan Backman reveals a brief moment in time when the Arctic was subtropical. More about world climate change can be found in our Climate Change featured story .
Small Adélie penguins live throughout the Antarctic, but are most abundant in the area of the Ross Sea. They lay eggs on the few rocky outcrops of land not covered in ice. Scientists have determined...
Antarctica is almost entirely covered by ice sheets up to two miles (3 km) thick, which contain roughly 70% of the world’s freshwater. The great ice sheets spill out to sea as floating ice-shelves...
The threat that climate change poses to polar bears has received a lot of attention, but they are not the only Arctic species at risk. Ice-loving seals, such as harp, hooded and ringed seals, are...
