Scientists have found that in the last year an increase of warm waters bleached corals of the Great Barrier Reef in Australia. The warm waters make the corals lose colors and turn white, which is an indicator that their metabolism has been affected. More than the half of the area of the Great Barrier Reef have experienced several bleaching in the last years. Some scientists have concluded that this abnormality can be attributed to climate change.
Global warming is a serious issue that is causing losses that were caused in years before only by El Nino phenomenon. Now bleaching is occurring over consecutive years, and people are expecting the reef to have the ability to recover from this.
