Severe Coral Reef Bleaching Now ‘Five Times More Frequent’ Than 40 Years Ago

By Daisy Dunne

The scale of bleaching has been rising steadily in the last four decades, a study author told Carbon Brief, with the global proportion of coral being hit by bleaching per year rising from 8 percent in the 1980s to 31 percent in 2016.

The findings indicate that "coral reefs as we know them may well vanish in the lifetime of the youngest of us" if no efforts are made to rapidly curb climate change, another scientist told Carbon Brief.

Could the Great Barrier Reef Heal Itself? New Study Offers Cautious Hope

Australia's Great Barrier Reef may be able to heal itself from bleaching events, starfish and other disturbances with the help of a group of "source" reefs, according to recent research.

The study, conducted by researchers from the University of Queensland, CSIRO, Australian Institute of Marine Science and the University of Sheffield, found that three percent of the coral reefs in the Great Barrier Reef are "robust source reefs." In order to meet the criteria of a "source reef," the reefs need to be well-connected to other reefs through shifting currents but also be able to sustain bleaching events and be less susceptible to crown-of-thorn starfish outbreaks.

62 Natural Wonders of the World at Risk From Climate Change

By Joe McCarthy

The marshy expanses of the Everglades in Southern Florida contain hundreds of species of animals, including flamingos, alligators and manatees. Clusters of mangroves span its coastline, acting as ecosystem hubs, and if you take a boat through the region, you'll see countless plants that are native to the area.

But the Everglades, which have been around for more than 5,000 years, are collapsing, as saltwater intrudes from rising sea levels, pollution seeps from surrounding industries, invasive species kill off native species, bad water management techniques dry parts of the wetland, and climate change intensifies.
