what will happen to polar bears of climate change continues
Answers
Answer:
Temperatures in the Arctic are rising at least twice as fast as the global average and sea ice cover is diminishing by nearly four per cent per decade.
The loss of sea ice affects polar bears’ ability to find food, studies show. Polar bears feed on ringed seals that live at the ice edge, getting two thirds of the energy they need for the entire year in late spring and early summer. With the ice retreating earlier in spring and forming later in winter, the bears have less time to hunt prey and have to go without food for longer.
Scientists have found this can result in a decline in body condition and lower average weight in adult females. Fewer cubs survive and the ones that do are smaller, research suggests.
While polar bears have shown some ability to adapt to changes in their surroundings – for example, by foraging for food on land – scientists project polar bears will become more food-stressed as sea ice diminishes and populations will decline.
Prof Andrew Derocher, expert in polar bear ecology and conservation at the University of Alberta, tells Carbon Brief:
“Without sea ice, there is no sea ice ecosystem and losing that ecosystem includes losing polar bears”.
There are other impacts of climate change on polar bears, too. Warming has been linked to increases in contamination and exposure to diseases. Unusually warm weather in winter can cause dens to collapse, which females build to birth and protect their young.
Answer:
Polar bears will get extinct.
Explanation:
if global warming continues in this same rate, very soon the polar ice caps will melt and the habitat for the polar bears will be destroyed.
Thus they will get extinct.
