How is climate change affecting polar bears in their natural habitat?
Declining Sea Ice
Climate change is causing a significant decline in Arctic sea ice, which is crucial for polar bears as they rely on it to hunt for seals. With the ice melting at a rapid pace, polar bears are struggling to find food and are facing starvation.
Migration Challenges
Polar bears are also facing challenges in migrating to new areas as their traditional habitats disappear. This forces them to travel longer distances in search of food, leading to increased energy expenditure and decreased chances of survival.
Rising Temperatures
The rising temperatures due to climate change are impacting polar bears' ability to regulate their body temperature. As a result, they are at a higher risk of heat stress and are more vulnerable to diseases.
Reproduction and Cub Survival
Climate change is affecting polar bears' reproductive success, with shorter ice seasons leading to a decrease in cub survival rates. This poses a threat to the future population of polar bears.
