As per reports, polar bears are starving as Arctic sea ice melts in Canada’s Hudson Bay due to global warming. This is happening due to longer periods without Arctic sea ice, fueled by the climate crisis. These apex predators traditionally rely on the frozen ocean surface to access their primary prey. Notably, their primary pretty is fatty seals like ringed and bearded seals.

As global warming extends ice-free periods in the Arctic, polar bears are forced to spend more time on land. It’s worth noting that food sources are scarce for them on land.

Recent research conducted on 20 polar bears in the western Hudson Bay highlights their struggle to adapt. The study was led by Anthony Pagano from the US Geological Survey. It utilized video camera GPS collars to track the bears for three-week intervals over three years.

The findings, published in Nature Communications, revealed that some bears reduced activity and tried to conserve energy akin to hibernation. However, most of them remained active.

Those active polar bears have reportedly been searching for alternative food sources. Some bears were observed eating grasses and berries and even scavenging a seal carcass and a gull. One bear embarked on a lengthy swim spanning 175 kilometers.

Despite their resourcefulness, the bears’ terrestrial foraging efforts failed to provide sufficient calories to sustain them. Nineteen out of the 20 bears studied lost weight during the ice-free period.

This is equivalent to the weight loss during fasting. This prolonged time on land significantly heightens their risk of starvation.

Melanie Lancaster, a senior Arctic species specialist at the World Wildlife Fund, emphasized the urgency of the situation. She linked polar bear survival directly to climate change. With only 25,000 polar bears left in the wild, immediate measures are imperative.

Experts emphasize the necessity of curbing greenhouse gas emissions to preserve polar bear habitats. Anthony Pagano stressed the importance of adhering to the Paris Agreement‘s target of limiting global warming to 1.5°C above pre-industrial levels.

However, current trends indicate that temperatures are already at 1.2°C above pre-industrial levels. At the same time, sea ice is continuing to dwindle.

John Whiteman of Polar Bears International emphasized that halting ice loss is the only viable solution to save polar bears. He emphasized that the fate of these majestic creatures is intrinsically tied to the health of Arctic ice.

Polar bears starving as Arctic sea ice melts is a stark reminder of the devastating impact of climate change. The struggle of polar bears in Hudson Bay shows how climate change is affecting wildlife. Urgent global action is needed to mitigate these effects and secure the future of these iconic Arctic predators.
