Emperor Penguins Expected to Disappear By 2100

Protected under the Endangered Species Act, the population of emperor penguins is now supposed to recover and is on the rise.

The Endangered Species Act is a law protecting animals that are listed as threatened or endangered. The act was “designed to protect critically imperiled species from extinction as a ‘consequence of economic growth and development untampered by adequate concern and conservation.’”

As part of the Endangered Species Act, emperor penguins cannot be harmed, killed, imported or exported. Designated “critical habitat areas” — where protection for their land and water is provided — were also created for these species as part of their recovery.

Emperor penguins were initially petitioned to be considered endangered in 2011 by the United States Fish and Wildlife Service. It was only recently that this petition was accepted and put into effect on Oct. 25.

Prior studies were conducted to estimate the population of emperor penguins and to evaluate the need to list them as endangered under the law.

“We estimated the breeding population of emperor penguins at each colony during 2009 and provided a population estimate of ∼238,000 breeding pairs,” concluded one study. “This translates to a total population of ∼595,000 adult birds.”

Although these numbers showcased steady breeding rates, scientists now predict that 99% of emperor penguins may disappear by 2100 due to rising temperatures.

Global rising temperatures are a direct result of fossil fuels burned by humans. Fossil fuels emit carbon dioxide that gets trapped in the atmosphere – resulting in global warming.

This is not good news for the emperor penguin population, native to Antarctic sea ice.
