Climate Change and Penguins
Transcript of Climate Change and Penguins
For the Adelie penguins it's a whole different story. Unlike the the other two species of penguins, the Adelie is benefiting from the climate change. Researchers have found that at the population size of an Adélie penguin colony on Antarctica's Beaufort Island near the southern Ross Sea increased 84 percent (from 35,000 breeding pairs to 64,000 breeding pairs) as the ice fields retreated between 1958-2010, with the biggest change in the last three decades. They also found a increase in population density for the species. Scientists believe the whole reason why this penguin is striving is because areas of once impenetrable pack ice have loosened allowing penguins easier access to open water. This makes it easier for the penguin to get food and to travel.
Scientists believe that half of the population of penguins in the Antarctic region has been depleted in the last 50 years due to the climate change.
It is the species known as the Emperor Penguins that have seen the largest losses.
After a few weeks, chicks can stand on the ice but are protected by their parents from the cold. If the ice disappears before the chicks can take care of themselves they will be swept into the sea.
The breeding population of chinstrap penguins has declined significantly as temperatures have rapidly warmed on the Antarctic Peninsula. Studies from the National Science Foundation (NSF) show that it's the changing climatic conditions, rather than the impact of tourism, have had the greatest effect on the chinstrap population. Over a period of less than 10 years the chinstrap population has decline by almost 40%. Scientists believe that if the ice water recedes krill number decrease which is very bad because the Chinstrap favorite meal is krill. Since the ice is melting at such a fast pace the Chinstrap have no place to breed, at this rate the Chinstrap will be gone very soon.
How to Prevent

Gillis, Justin, and Kenneth Chang. "Scientists Warn of Rising Oceans From Polar Melt." The New York Times. The New York Times, 12 May 2014. Web. 13 May 2014.
This article helped me find about the global warming that is taking place in Antarctica. I learned that the ice melting could destabilize neighboring parts of the ice sheets and make the sea level rise 10 feet. I also learned that the ice melting at such rapid rate it's impossible for it to stop.

This article showed me a lot about the Chinstrap penguin. It talked about how the population of the Chinstrap are declining because of climate change. It said since the climate is getting warm it's killing all the krill that the Chinstrap eat, causing the Chinstrap to die.

This article also talked about how the warmer temperatures from climate change are actually benefitting the Adelie penguin. I found out that the population of the penguin has increased by 84% and the population density also has increased. I also found out that the researchers have satellites on the penguins and are going to continue to look at the penguin to see if they’re population continues on to increase.

This article focused on the Emperor penguins, I found out that that the Emperor penguins stand almost 4 feet tall and are the largest penguin species. The rapid climate change is making breeding almost impossible for the penguin. If the climate keeps continuing to keep melting at this rate the penguin will be extinct by 2100.

This article focused on the Adelie penguins and how the how warm climate could actually be helping out the species. I learned that in the southern portions of the Antarctic coast, areas of once impenetrable pack ice have loosened allowing penguins easier access to open water. This is the main reason why the penguin is striving.
