March 23, 2013 The city of Gladstone is the world's fourth largest coal-export hub. It's also a jumping off point to the southern end of the Great Barrier Reef. But coal mining could eventually kill the reef that Australians revere.
March 22, 2013 There's some evidence that carbon dioxide we pump into the atmosphere has slowed the development of coral reefs. So researchers are adding antacid to the water in a tiny part of the Great Barrier Reef, to see whether the corals will grow faster if their water supply is less acidic.
March 20, 2013 Seaweed might not be as flashy as coral, but it plays an important role on the reef. They compete for space, and rising carbon dioxide levels could someday tip the balance of power.
March 19, 2013 The tropical island set in turquoise water just off the Great Barrier Reef is the site of an experiment to see what will happen to coral reefs as the ocean absorbs ever more of the carbon dioxide and heat we've added to our planet's thin skin. The results weren't so pretty.
