As the effects of climate change worsen, we may start to see more and more grizzly and polar bear hybrids.
while the heat pushes grizzly bears north.

The result? This breeding act is creating hybrid"pizzly bears," sometimes called grolar bears, and according to some scientists, the pizzlies could be here to stay., can be identified by their off-white coat and elongated schnoz, and is"more resilient to climate change and better suited for warmer temperatures," DeSantis says."We've known about pizzlies for quite some time, but their occurrence may be more common with ongoing Arctic warming.
Since 2006, the effects of climate change have worsened and sightings of pizzlies have become more common. For example, a 2017 research published in the journalscientists recorded eight pizzlies that were the offspring of a female polar bear who mated with two different grizzly bears. Furthermore, since the two animals only diverged around 500,000 to 600,000 years ago, their offspring can reproduce. One study has found a hybrid that was born from a pizzly mating with a grizzly.
Scientists are studying how well these hybrids are suited for life in the wild."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,"
