Great Barrier Reef

Reef scientists have called for urgent action on climate change or humanity could have a very different underwater world by midcentury.
Climate change remains the greatest threat to the iconic structures, which are disappearing around the globe at dire rates.
Back-to-back mass bleaching events have devastated large parts of the reef, prompting dire warnings of climate change.
“What we need is for the temperature to stop rising," a scientist said, noting climate change remains the most urgent danger to the delicate ecosystems.
If global warming trends continue, the Great Barrier Reef will be destroyed.
“I’m not sure I have the fortitude to do this again,” one of Australia's top scientists wrote.
The iconic structure was hit with devastating, back-to-back bleaching in 2016 and 2017.
The latest generation of Corsola in Pokémon Sword and Shield is a "ghost" type that was "wiped out" due to sudden climate change.
Climate change remains the greatest threat to the Australian natural treasure, and things are not looking good.
The volcanic rock could transport Pacific sea organisms to restock the bleached reef off Australia.
The catastrophic die-off from recent ocean heat waves severely affected the reef's ability to produce new corals and bounce back.
While none will single-handedly save the world, extreme and sometimes controversial plans are gaining traction.
Last year's oceanic heat wave wasn't as destructive as one the year before, scientists said.
Rising temperatures in 2016 caused a catastrophic die-off of almost 30 percent of the iconic reef.
“The dire situation is here now," said the coordinator of NOAA’s Coral Reef Watch.
In the northern Great Barrier Reef, juvenile green sea turtles are 99 percent female.
"Before the 1980s, mass bleaching of corals was unheard of."
