Question

1. how is climate change threatening the availability of sea ice?

global warming is increasing the temperature and ice caps are melting polar bears depend on the ice to survive so if the ice caps arent available then the polar bears are effected

1. according to the article, explain two reasons why sea ice is so important to polar bears.

1. what main ways do pizzly bears resemble a grizzly bear?

1. according to the article, what proof is there that pizzlies can be made in the wild?

Explanation:

1. 1. Climate change drives global warming, raising planetary temperatures. This causes polar ice caps and sea ice to melt at an accelerated rate, rapidly reducing the total available sea ice coverage.
2. - Hunting Platform: Polar bears use sea ice as a floating platform to hunt their primary prey, seals, by waiting at seal breathing holes in the ice.

• Travel & Habitat: Sea ice allows polar bears to travel across large stretches of the Arctic ocean to move between hunting grounds, mate, and access denning sites on stable ice or coastal areas attached to ice.

1. Pizzly bears typically resemble grizzly bears in having a humped shoulder profile, longer, thicker brown/tawny fur with lighter tips, a broader face with a shorter snout, and they are more adaptable to living and foraging on land for berries, roots and terrestrial prey like grizzlies do.
2. Confirmed wild Pizzly bear sightings and genetic testing of bears captured in the Arctic have verified that polar bears and grizzly bears are interbreeding naturally in the wild as sea ice loss forces polar bears onto grizzly bear coastal habitats.

Answer:

1. Global warming from climate change raises temperatures, melting polar sea ice and reducing its availability.
2. 1. It is their primary hunting platform for seal prey
3. It enables Arctic travel between habitats and mating grounds
4. They share grizzly bear physical traits (shoulder hump, broader face, brown fur) and land-based foraging behaviors.
5. Genetically verified wild-caught Pizzly bears and documented natural wild mating events between the two species serve as proof.
