Why is climate change a threat to penguins?
If greenhouse gas emissions continue to rise at levels similar to today — causing temperatures to rise and Antarctic Sea ice to shrink — penguin population numbers will diminish slowly until about 2040, after which they would decline at a much steeper rate as sea ice coverage drops below a usable threshold, with the …
How is global warming affecting emperor penguins?
The penguins live much of the year on Antarctic sea ice, which is disappearing or breaking apart because of the heat-trapping gases released by humans’ use of fossil fuels. The penguins need the ice to breed, raise their young and escape predators.
What is climate change doing to the penguins?
The study, published this week in the journal Global Change Biology, estimates that 98 percent of emperor penguin colonies will become quasi-extinct by 2100 if greenhouse gas emissions continue at their current pace.
Do penguins cause global warming?
Emperor penguins are especially vulnerable to climate change because, like polar bears in the Arctic, they depend on sea ice for vital life activities like breeding, feeding, and molting. Too little sea ice, and the penguins don’t have enough protection from predators or space for molting.
What is the tallest penguin ever?
What eats a killer whale?
Killer whales are apex predators, which means they have no natural predators. They hunt in packs, much like wolves, which are also at the top of their food chain.
