Global Warming Effects Penguins
How global warming is effecting penguins in Antarctica
During the 1970s, scientists found over 250 breeding pairs. By 1999, the population went down to only 20 breeding pairs. By 2009, they completely disappeared.
Emperor penguins are the largest and most recognizable seabird in Antarctica. They have a huge death rate every breeding season and most don't live afterwards Only half of the survivors live to see another year. If temperatures continue to rise at the rate it is now, then sea ice will shrink causing the penguins to diminish slowly. Emperor penguins raise their young exclusively on ice. When sea ice breaks before the chicks have matured and grown their water proof feathers, they can be dragged into the ocean and die. So, sea ice will cause the number of breeding pairs to drop. 3,000 breeding pairs could fall to 500-600 by 2100.
Ice Melting Effects Penguins
If the ice breaks up and disappears near the early breeding season, massive breeding failure will occur. Disappearing sea ice can have an affect on food source for penguins, as well. Fish, squid, and krill, Penguin food, feed on sea plankton which live under the ice. If the ice continues to melt, sea plankton will die, which will alter the food chain. Transportation is a big contribution ice makes to Penguins
Recently, many species of penguins have been changing their lives to adapt to climate change. This results in the increased risk of adult penguins dying and offspring not making it to maturity. Even some of the changes certain species have been making is causing them to get stressed and no longer participating in reproduction.
