How accurate were Al Gore's predictions about coral reefs and marine life in 'An Inconvenient Truth'?

Al Gore's prediction about coral reefs experiencing species loss at 1000 times the natural variability rate still stands today, but the situation has actually worsened. Recent years have seen very hot oceans, and according to the UN Environmental Program, marine life loss is accelerating dramatically. The impact is so severe that by the end of the century, a quarter of all marine life is projected to disappear. While 'An Inconvenient Truth' contained some incomplete or overstated elements, Gore's core message about unprecedented warming rates and marine ecosystem damage has proven largely accurate, with current conditions often exceeding his original warnings.
