Melting Arctic Ice Imperils Polar Bears
CorrectionA photo that had accompanied this story was later removed because the caption was misleading.
The National Snow and Ice Data Center reports that sea ice could reach all-time record lows in these last few weeks of the Arctic summer.
Margaret Williams, who directs the World Wildlife Fund's Alaska office, says that during a helicopter flight Thursday she saw five polar bears, including a cub, in open waters.
Williams says though it's not unusual to see polar bears swimming, such ice conditions are unusual.
