OCEAN SPECIES ARE IN TROUBLE: U.S. CORAL REEFS COULD DISAPPEAR WITHIN DECADES, SCIENTISTS WARN

The Extinction Chronicles

Global warming is taking its toll on coral reefs in U.S. waters, and many of the marine sanctuaries near Hawaii, Florida and the Caribbean are expected to disappear within a few decades, according to scientists at the National Oceanic and Atmospheric Administration (NOAA). Despite strict conservation efforts in various protected areas in American seas, in a Tuesday report, NOAA reef experts told The Guardian that many reefs off Hawaii and Florida will start to see impacts from rising ocean temperatures as soon as this summer.

Some 70 percent of coral reefs across the globe have been affected by bleaching—which NOAA said is the most obvious visual indication of climate change in the marine environment. Coral reefs are typically vibrantly colored by photosynthetic algae called zooxanthellae—which provides the reef with food and oxygen. But exposure to carbon dioxide is causing water temperatures…
