Why are polar bears dying because of global warming?

Answer 1

Since most penguins live in the poles, and global warming is warming the planet, the snow and ice in the poles are slowly melting because of the harmful rays of the sun. Penguins are losing their lives, because of this.

Answer 2

Excessive warming is causing ice floes to shrink every year at an abnormally fast rate and earlier and earlier each summer. Polar Bears use these ice floes over the ocean during winter (and early spring) to hunt. Without these ice floes their hunting ground is limited and they cannot build up good reserves of body fat for the summer months when there is little food.

Answer 3

It's affecting them differently but, mainly, they need to walk on ice to live their lifestyles. Polar bears hunt for seals on the ice, if they can't get out there because the ice has melted out of season, they starve. They move to new places searching for food, and often encounter humans, who either shoot them, or move them back to where they left. Penguins migrate, they must cross the ice to complete the ritual shown in "March of the Penguins". I'm not too concerned, they can stop that silly ritual if they need to, but I'm no expert. Also, more obviously, they are both designed to keep warm in frigid temperatures. If it gets too warm, they overheat and die. Penguins are probably in a better spot than the polar bears because the penguins can swim, so they can keep cool and catch fish.

Answer 4

Penguins occupy the south polar cap, and some islands extending northward from there. Although Antarctic sea ice extent has increased in recent years, total Antarctic ice volume has declined. The south pole average temperature remains very cold, and we would not expect significant change there for centuries to come.

In summary, we would expect the climate impact on the penguin population to remain relatively minor, at least over the next century.

Answer 5

As you may know, penguins naturally live in an icy, cold environment. If global warming is present their habitat will be melting until it gets destroyed and the penguins will either have to adapt to the new environment, or they could just die.

Answer 6

It is impossible to know an exact figure. It is possible that penguins are dying because krill populations are changing due to changes in ocean temperatures and currents. Penguins eat fish, which eat smaller fish, which rely on krill. But it is impossible to have an accurate count of penguins, living or dead. Scientists rely on estimates.

A:The temperature rises, melting ice, water rises. The penguins have less food with the fish dying/leaving. They starve causing drops in the population. and also due to the pollution released into the atmosphere by mankind and when those pollutants are synthesised into the marine plant life and are eaten by krill and other small fish the pollutants carry and when eaten by the penguins at best they have trouble with the offspring, all sorts of birth defects, or they cannot produce any fertile offspring, at worst the pollutants will spread through out the food chain. A:Penguins are dying they are flightless and are losing feeding and mating land.
