Scientists say warming seas kill off coral reefs Pacific, Atlantic oceans
2015-07-07 06:59:00| Climate Ark Climate Change & Global Warming Newsfeed
Guadian: Abnormally warm ocean temperatures are creating conditions that threaten to kill coral in the equatorial Pacific, north Pacific and western Atlantic oceans, the National Oceanic and Atmospheric Administration said on Monday. Coral bleaching occurs when coral is stressed by changes in its environment, causing it to release algae living in its tissue. The coral then turns pale or white and becomes more susceptible to disease. In severe cases, it can die, permanently changing the habitat for fish...

Coral breeding may help cooler reefs survive warming: study
2015-06-25 20:19:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Corals that naturally thrive in the hottest tropical waters can be bred with cousins in cooler seas to help them survive mounting threats from global warming, scientists reported on Thursday. Tests of corals in warm waters on Australia's Great Barrier Reef found they were able to survive bigger temperature rises than those of an identical species in cooler seas 300 miles (500 kms) south, according to a University of Texas at Austin study published in the journal Science. The study, by scientists...

Coral Reefs in Palau Defy Ocean Acidification

Nature World News: As humans continue to release harmful fossil fuels into the air, the Earth's oceans are absorbing more and more atmospheric carbon dioxide (CO2). Consequently, in a process known as ocean acidification, this CO2 reacts with water molecules and lowers the ocean pH, making it more acidic. This process also removes carbonate, an essential ingredient needed by corals and other organisms to build their skeletons and shells. As a result, these calcifiers are struggling in Earth's changing oceans, and...

Coral Reefs in Danger, Fish Are the Answer
2015-04-09 21:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: It is no secret that in the midst of climate change, coral reefs around the world are suffering. However, a warming world is not the only factor putting these reefs in danger - overfishing also plagues these colorful ecosystems. And now new research offers a glimmer of hope, finding that fish are the answer to their problems. According to scientists from the Australian Institute of Marine Science, Wildlife Conservation Society (WCS), James Cook University, and other organizations, fish are the...
