What will be the future of Adelie Penguins?

The news article “Penguins die in 'catastrophic' Antarctic breeding season” by BBC talks about a tragic incident that is happening in the Arctic due to global warming. It was reported that “all but two Adelie penguin chicks starved to death” due to the high amount of ice that appeared late in the season and as a result, the chicks could not find food to eat. The adults did survive as they are better prepared and are able to walk further in order to find food for themselves. This is the “second bad season in five years after no chicks survived in 2015” the only difference is that this time two chicks survived. Conservation groups are taking action as they are proposing a new marine protection area that would take place in east Antarctica in order to preserve the penguins and their habitat. Many people are concerned as if this continues, Adelie penguins may become endangered.
The first academic article I found is “Proliferation of East Antarctic Adélie penguins in response to historical deglaciation” by the authors Jane Younger, Louise Emmerson, Colin Southwell, Patrick Lelliott, and Karen Miller. This article was published in November 2015 in the journal BMC Evolutionary Biology. This article is relevant because it specifically talks about the Adelie penguins in the East Antarctic and the effect ice melting ice has on them. This study uses many methods to observe and investigate the population trajectory of Adelie penguins.
The second scholarly article I found is “Spatially Extensive Standardized Surveys Reveal Widespread, Multi-Decadal Increase in East Antarctic Adélie Penguin Populations” by Colin Southwell, Louise Emmerson, John McKinlay, Kym Newbery, Akinori Takahashi, Akiko Kato, Christophe Barbraud, Karine DeLord, and Henri Weimerskirch was published in October 2015 in the journal PLOS ONE. This article is relevant to the news as it talks about the changes in the Antarctic and the effects it has on the penguins. This survey looks at these changes and provides explanations and insight into this environment and its alterations.
The third and last scholarly article I found was “Adélie penguin population changes at Stranger Point: 19 years of monitoring” by Mariana A. Juáres, Mercedes Santos, Javier Negrete, Jorge A Mennucci, and Pablo J. Perchivale. This article was published in October 2015 in the journal Antarctic Science. This article is relevant as it evaluates the increase and decreases in the population of Adelie penguins and it explains why there is such as increase and or decrease. It also encourages action as it explains that if this continues there will be an “unfavorable impact on the future population of this species”.
