The outlook for the Great Barrier Reef has worsened from ‘significant concern’ to ‘critical’, the International Union for Conservation of Nature says. the world's largest coral reef systems, according to two Australian researchers. “As summers grow hotter and hotter, we no longer need an El Niño event to trigger mass bleaching at the scale of the Great Barrier Reef,” Professor Hughes says. VIDEOGRAPHIC The current bout of coral bleaching on the Reef, “the third in just five years”, is the “most severe and the most widespread” ever. Increased frequency of severe weather events, such as cyclones and record rainfall levels can destroy reef structures and send an influx of freshwater and sediment further out from the coast on to the Reef. Satellite data showed the thermal stress and environmental fallout from the bleaching was greater than the previous 20 years combined. ... [+] One magazine describes the marine phenomenon as “larger than the Great Wall of China and the only living thing on earth visible from space.”. The coral reef biome experiences an average yearly precipitation of 78.75 inches. Professor Hughes emphasises the alarming speed at which the bleaching incidents were occurring globally. “Australia is committed to playing its role in a global response to climate change, it is investing unprecedented amounts protecting the reef, in bushfire wildlife and habitat recovery and in supporting our world heritage places,” the minister’s spokesman said. Climate Australia’s Great Barrier Reef is critically deteriorating according to the International Union for Conservation of Nature, or IUCN. Others include the Everglades of Florida.

Small-scale bleaching is a common sight on the reef, but 1998 marked the first year that saw widespread bleaching, Hughes says. Climate change is caused by global emissions of greenhouse gases, such as carbon dioxide from the burning of fossil fuels (coal, oil and natural gas), agriculture and land clearing. After the climate emergency, the next two largest threats to heritage sites are invasive alien species and tourism impacts. The results are “not a pretty picture”. After climate change, the next two significant threats to these natural sites are invasive alien species and tourism impacts. The IUCN’s director general, Bruno Oberle, said countries owed it to future generations to protect the world’s “most precious places”.
