While the effects of climate change have been felt in different ways around the globe, the polar regions have been subject to outright changes to their respective topographies, as ice acts as a major feature of their landscapes. Scientists are concerned about the impact of these changes on Arctic wildlife, particularly ones that have adapted to depend on ice formations for survival, such as the polar bear.
One effect of the southward push of the habitat of the polar bear is that they are cross-breeding with grizzly bears, producing a hybrid called "pizzly bears". While encounters with the hybrid pizzly have been documented in the past, there are increasing reports of sightings of these odd ursids.
