Polar bears, of course, are better equipped for winter than you and I. Their heavy fur even grows on the bottom of their feet to keep them warm on the coldest days and to provide traction for walking on ice. While their fur is white for camouflage purposes, their skin is black to better absorb warmth from the sun.
This January was one of the coldest and snowiest on record for much of the U.S., yet it was unseasonably hot in Alaska. Less snow and ice in the Arctic makes it harder for polar bears to survive.
This is especially true for females who give birth in winter, usually to two cubs. The cubs stay with the mother for as long as 28 months. A warmer winter makes it harder for her to feed and protect her cubs.
