Which is a main argument the writer gives to show the dangers to penguins from climate change ?

The correct answer to this open question is the following.

Although there is not text or reference attached, we can say that one of the arguments the author gives to show the dangers to penguins from climate change is the melting of ice in Antarctica that put this specie in danger. The author says in its article that emperor penguins are at risk of disappearing by 2100 due to climate change effects such as the melting of the ice. This and other species that live in Antarctica could be on the brink of extinction if somebody does not do something soon.
