Polar bears, the largest carnivorous mammals on Earth, have lost an extraordinary portion of their habitat due to the planet's warming. As Arctic Ocean sea ice disappears, polar bears must travel further to hunt for food.

Polar bears have long been an icon of climate change because their habitat is visibly shrinking as the planet warms. The largest carnivorous mammals on earth, polar bears rely on Arctic sea ice for hunting seals, their primary food source. As CO2 emissions continue to warm these environments, sea ice is melting at 14% per decade. Scientists project that this decline will reduce the global population of polar bears by two-thirds, to less than 10,000 by 2050.
