Major Impact on Oceans

After read a climate article I've realized that its not just the air thats being affected its the ocean to. Greenhouse gas are warming the world's oceans and providing a new threat to coral reefs. Which are among the most threatened of all marine ecosystems. Even the smallest warming of a degree or two above normal temperatures can cause a breakdown the corals and their symbiotic algae. In 1998, there was a worldwide mass bleaching events affecting 80% of the coral reefs in the Indian Ocean, 20 % of which died. In 2005, severe bleaching occurred over most of the Caribbean as a result of warming water temperatures. We have lost 80 % of the reef corals in the Caribbean over the past three decades.
