Climate Change Prompts Emperor Penguins To Find New Breeding Grounds 215

An anonymous reader writes Researchers have discovered that emperor penguins may not be faithful to their previous nesting locations, as previously thought. Scientists have long thought that emperor penguins were philopatric, returning to the same location to nest each year. However, a new research study showed that the penguins may be behaving in ways that allow them to adapt to their changing environment. Lead author Michelle LaRue said,"Our research showing that colonies seem to appear and disappear throughout the years challenges behaviors we thought we understood about emperor penguins. If we assume that these birds come back to the same locations every year, without fail, these new colonies we see on satellite images wouldn't make any sense. These birds didn't just appear out of thin air—they had to have come from somewhere else. This suggests that emperor penguins move among colonies. That means we need to revisit how we interpret population changes and the causes of those changes."

    AGW is not based solely on this observation, and the evidence for it is overwhelming. Yes, climate change has and always will happen, but short of an asteroid strike it's never happened this fast before. Humanity needs the world the way it currently is, otherwise it will face massive issues on top of the normal issues faced every day across the world.
