Could global warming be killing polar bears?
The weather temperature is rising because of global warming, this is due to changes in the entire Arctic eco system. Scientists suggest that warmer temperatures mean less lack of ice that polar bears depend on for hunting. As their normal habitat gets hotter it goes down in size, this consequence leads to fewer polar bears. For the polar bear, which is a non replaceable symbol of the Arctic, climate change could cause extinction of polar bears. Temperatures in the Arctic are increasing at almost twice the rate as the rest of the world.
Since 1973 the Arctic sea area ice has become smaller by more than 2% per 10 years. Greenland’s huge ice sheet carries enough melted water to …show more content…
Others also at risk include ivory gulls, pacific walruses, ringed and hooded seals and narwhals, small whales with long spiral tusks.
One of the problems is that other animals are moving north, encroaching on their territory spurred by increasing temperatures pushing out native species.
The animals are also struggling with the loss of sea ice.
“The Arctic as we know it may soon be a thing of the past, said Eric Post, Associate Professor of Biology at Penn State University, who led the latest study published in the Journal of Science”.
Recent projections suggest polar bears could be extinct within 70 years.
“But we think this could be very conservative estimate the outlook is very bleak for them and other creatures such as ringed seals”.
