The Impact of Climate Change on Polar Bears

Polar bears, the largest bear species, are adapted to life in the Arctic, spending most of their time on pack ice hunting seals. They are strong swimmers but face challenges due to climate change, which is reducing their hunting season and causing population declines. The World Conservation Union lists them as vulnerable. In Hudson Bay, ice melts earlier, reducing bear numbers by 20% in 30 years. In Alaska, ice retreat has led to drowning incidents. The US Geological Survey predicts a two-thirds population decline by mid-century due to continued sea ice loss.
