Emperor Penguins
Emperor Penguins are the largest Penguin species
in the world. Growing up to 44 inches tall it is
simply, as the name states, the emperor of all
Penguins. They weigh up to about 40kg after
feeding. Emperor penguins can only be found on
Antarctica and a few of its surrounding islands.
Emperor Penguins dislike open waters and can
usually be found near large ice bergs or
somewhere along the coast near water and land.
There are around 250, 000 emperor Penguins
living in their natural habitats today. The
emperor penguin had, for many years, a fairly
stable population. They have never been
classified as an endangered species and we hope
to keep it this way for years to come.

Adelie Penguins
Unlike the Emperor penguin, the Adelie penguin is
around 43cm tall when fully grown and usually
only weighs around 5kg, somewhat less than its
superior Emperors. These little Penguins are not
as adventurous as the Emperor, they prefer to
stay inland going no further that the beginning
stages of the pack ice. There are over 5 million
Adelie penguins in Antarctica and their
population is on the increase.

The Effect Of Global Warming On Antarctic Penguins
As the big chunks of ice fall off the edges of
Antarctica penguins are forced to move further
inland. In January 2002, 3,250 km2 of the Larsen
Ice Shelf disintegrated. Eugene Domack a Hamilton
College geologist said that the Larsen Ice Shelf
had been stable for over 12,000 years. This is
the effect of global warming. When glaciers
fracture and fall of the main part of Antarctica
they fall into the ocean, thereby raising the sea
level. The Effect on Adelie Penguins Adelie
Penguins have lived on antarctica for over 600
years. Over the past 50 years there has been a
substantial depletion of their population. The
Adelie penguins face a rival threat. Chinstrap
penguins. Years ago there was no Chinstrap
penguins found in the Antarctic region at all but
due to the changes in temperature caused by
global warming they have moved to find a colder
and better suited climate which can be found in
Antarctica. Krill is the main source of food for
penguins and other sea animals in Antarctica.
Global warming has reduced the amount of surface
ice where the Krill tend to reproduce and with
more open water, snow falls and freezes the krill
before they have a chance to live. So many
penguins die of starvation in search of krill.

Conservation
Currently all 17 species of penguins are legally
protected from hunting and egg collecting. At
least three species are considered at risk. The
Antarctic Treaty was signed by 12 nations in 1959
and reauthorized in 1991 to protect Antarctica
and preserve its living resources. The Treaty
makes it illegal to harm, or interfere with, a
penguin or its eggs. Every penguin specimen
collected with a permit must be approved by and
reported to the Scientific Committee for
Antarctic Research. Protection of habitat began
in the early 1900s. In 1919 the Tasmanian
Government stopped all interference of penguins
on Macquarie Island and made the island a
sanctuary. The Conservation Assessment and
Management Plan (CAMP) makes sure that the high
risk animals such as penguins are protected from
the interference of humans.

Global Warming Continued
Effect On The Emperor Penguin. The emperor
penguins are having a harder time of the whole
global warming effect. Their numbers have
decreased by over 50 in the last 50 years. Like
the Adelie penguin the Emperor penguins feed on
krill and as I said before their numbers are also
falling. This is an effect that warming has on
Antarctica. The fact that it is getting colder is
just as bad. As the krill numbers are low, the
female penguins go off in search of food, while
the male keeps the eggs warm. This journey of the
female penguins search for food has increased and
they take a great deal longer to find sufficient
food supply for the waiting males. Eventually the
male gets hungry, leaves the eggs, and the eggs
may end up freezing. This is why the temperature
must stay constant for the krill to regenerate
and for the penguin eggs to hatch properly. The
other reason for the melting of the ice is the
natural occurrences of circumpolar waves which
make a cold/warm cycle every 8 years. In the 70s
there was an ongoing warm which had a devastating
effect on the penguins. These are the main signs
and effects of global warming.
