Pizzly Bears Becoming More Common Due To Global Warming

There is a growing number of pizzly bears appearing in the wild due to an increase in polar bears breeding with grizzly bears.
Scientists say the increase in population is being driven by climate change, as the two species are forced to live closer together.
Climate change is forcing polar bears to move further south to find food, while grizzlies are expanding northwards.
Some claim that the species could be here to stay due to them inheriting features that may help them in a warming climate.
Usually, hybrids aren't better suited to their environments than their parents, but there is a possibility that these hybrids might be able to forage for a broader range of food sources, Larisa DeSantis, Paleontologist And Associate Professor Of Biological Sciences At Vanderbilt University in Tennessee.
Grizzly and polar bears can produce viable offspring due to them only diverging from each other less than 500,000 years ago.
The first sightings of pizzly bears were reported back in 2006 in the Northwest Territories of the Canadian Arctic.
