Have you ever thought, if all ice in Antarctica(南极洲) and the arctic(北极) melts due to the global warming, what will happen? But one thing is sure with 100% certainty, penguins in Antarctic and the arctic will be in big trouble.
Rising temperatures in coming years would lead to less sea ice in the Southern Ocean that surrounds Antarctica and fewer habitats and feeding grounds for penguins, says the World Wildlife Fund (WWF) in its report 2 Degrees is Too Much.
Antarctica and the Arctic are the most threatened regions from climate change. In the Antarctica, the temperature has risen 2.5 degrees in the past 50 years. This speed is nearly five times faster than that before the Industrial Revolution. It is mainly caused by burning fossil fuels. Unless nations reduce carbon dioxide emission, the world will warm by an average of 2 degrees in less than 40 years. Rich nations should agree to reduce greenhouse gas emission. Temperatures near the Poles have risen much faster, which has led glaciers on the Antarctic Peninsula to melt quickly.
The situation is quite critical, because in the past 50 years the number of emperor penguins(帝企鹅) has decreased by 50 percent across the whole Antarctica. On the northwest coast of the Antarctic Peninsula, the number of Adelie penguins(阿德利企鹅) has dropped surprisingly over the past 25 years.
Fifty percent of the habitats of the emperor penguin and 75 percent of the habitats of the Adelie penguin face a rapid reduction, or even disappearance, if the global temperature rises 2 degrees above pre-industrial levels.
With a 2-degree increase in global temperature and the decrease in sea ice thickness, emperor penguins will find it difficult to find new areas to live. With less sea ice, penguins could be pushed further south, but this could prevent them from hunting for food during the dark winters, because they need at least a few hours of daylight to find their food.
