Good news reefs: How corals survive a heating planet

2015-06-26 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Christian Science Monitor: As concern grows over the threat coral reefs face from pollution, destructive fishing practices, and especially climate change and ocean acidification, a research team has found that heat-tolerant corals pass along that tolerance to corals adapted to cooler waters. One of the key questions regarding heat tolerance is the extent to which it is genetically inherited or whether the corals build an ability to endure heat stress through repeated exposure, a process analogous to hardening tomato plants....

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

2015-06-11 19:06:00| Climate Ark Climate Change & Global Warming Newsfeed

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...

Australia: Great Barrier Reef's 'single biggest risk' climate change

2015-05-25 09:14:00| Climate Ark Climate Change & Global Warming Newsfeed

Financial Review: The chairman of the Great Barrier Reef Marine Park Authority, Russell Reichelt, says climate change posed the biggest risk to the long-term future of the reef but said he believed there was enough government funding at the moment to tackle the problem. Just days before UNESCO will make its decision on whether the Great Barrier Reef will be placed on the "endangered" list, Dr Reichelt said he was encouraged by the $140 million in extra funding from the federal government to improve water quality...
