When you picture the impacts of climate change, what animal comes to mind? Is it a polar bear floating on a thin chunk of ice, or maybe another cold climate species losing habitat like a walrus or a penguin?
Add butterflyfish to your thoughts about climate change, because a new study predicts that they, along with one-third of all coral reef fish, are losing reef habitat and are locally threatened with extinction from climate change.
Coral reefs are threatened by two aspects of carbon dioxide emissions, ocean acidification and climate change. Corals are susceptible to sustained periods of warmer water temperatures due to climate change, which causes them to bleach when they expel algae, turning them white.
