"After all, the rest of the Adélie penguins on the mainland, their habitat hit hard by climate change, have been steadily declining for the past 40 years. In fact, "nowhere is the climate changing more rapidly than on the Antarctic peninsula," Lynch said.
But some of the team's new findings suggest that although 1.5 million seems like a big number, it's not as large as it once might have been. After their initial analyses of recent satellite imagery, the team decided to look at past satellite images that date back to 1982.
They found that the Adélie penguin populations likely peaked in the late 1990s and "has been on a slow but steady decline ever since," Lynch said. The decline "is not catastrophic," but rather on the order of a 10 to 20 percent decline, she later added.
Because the Danger Islands are almost always surrounded by sea ice, they are more protected from krill fishing and other human interventions than other areas of the continent, Lynch said. But even so, the best working hypothesis is that the population decline there is probably also due to climate change."
