How is global warming threatening the lives of Antarctic animals?

Answer 1

Global warming refers to the rise in the global temperature due to the Greenhouse Effect. Global warming effects Antarctica's marine life by raising the temperature of the water, so that a lot of the fish are dying.

Answer 2

warming makes the ice melt earlier in the year, more rapidly and further than before, so that Polarbears (for example) cant walk on it safely to get to their instinive hunting grounds

so they suffer the most.

Answer 3

Krill (tiny crustaceans) and their food algae are at the bottom of the Antarctic food chain. Ocean warming and ocean acidification are reducing krill numbers.

Larger mammals such as whales, penguins and seals need krill either directly or indirectly through the food chain. In winters with shorter and smaller sea-ice coverage, krill reproduction is much reduced. Carbon dioxide in the ocean is turning the water more acidic making it more difficult for krill to form their shells.

Answer 4

Phytoplankton (algae) grow under the ice shelves of Antarctica. Warmer water is affecting the growth of phytoplanktons. Krill (zooplankton) need them to survive. These two are vital links in the food chain of the Antarctic. Whales live on krill. Penguins need krill and the fish that feed on krill. Seals and sea birds need the fish. Climate change is damaging the food chain in Antarctica and threatening the lives of the animals there.

Answer 5

Global warming is affecting Antarctic animals by causing their habitats to melt and shrink, such as sea ice for species like penguins and seals. Changes in temperature also disrupt their food sources, like krill and fish, leading to food shortages. Additionally, the warming ocean waters are affecting the ecosystem balance and increasing the risk of disease outbreaks among marine animals.

Answer 6

The ice shelves in West Antarctica are slowly moving into the sea and splitting off.
