Global Warming: When the earth gets way to warm causing water levels to rise and can wipe out all animals and their habitat.
Penguins live near cold temperatures, like in Antarctica. Sometimes, cold storms occur across the arctic every year.
Ways global warming affects them: Penguins are warm-blooded. That means that their body keeps the same temperature every day. If there body's trap too much heat, they'll die. When they swim, the sun's rays beat down on the ocean causing the water to rise. Then the penguins can't breathe.
Global warming affects their habitat. Glaciers melt because heat causes the sea level to rise.
