Not Just Rising Seas
Human-caused climate change is driving sea level to rise, but that is not its only impact to Biscayne National Park. For Biscayne’s precious underwater coral reefs, climate change is changing the chemical make-up of the water through ocean acidification.
See how ocean acidification affects our national parks from coast to coast.
In acidic oceans, stony corals, like this elkhorn coral, cannot grow their shells and exoskeletons, reducing growth and potentially leading to die-offs.
Within Biscayne, over 300 types of fish depend on coral reefs. This spotfin butterfly fish feeds directly on coral polyps. Reef fish survival is at risk as coral reefs decline. (Photo by Kara Wall)
Both sea level rise and ocean acidification are a result of human actions, like burning fossil fuels. Find out what you can do to reduce your contribution to climate change.
