Coral reefs and climate change

Since the beginning of the industrial revolution, the Earth’s average temperature has been rising, and the ocean's pH has been declining. Climate change is often recognized by melting ice in polar regions and changes to glaciers. But climate change also affects the tropical oceans and ecosystems. Warmer ocean temperatures and ocean acidification are affecting coral reef ecosystems worldwide. Learn how climate change affects coral reefs and what scientists are doing to find solutions.
