Reef Erosion With Acidity: A 'Double Whammy'
2014-11-27 20:06:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Here's something you may not have known: tropical coral reefs are constantly building up and breaking down. In healthy ecosystems, the building will outpace the breakdown, keeping reefs growing and sturdy even as their erosion feeds predators (like worms and the unusual parrotfish). However, in recent years, researchers have begun to worry that in the wake of elevated levels of ocean acidity our reefs are eroding faster than they can grow. Extensive records have shown that one of the most iconic...

Marine Economy Takes Dive as Ocean Acidity Rises
2014-08-17 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: The waters off the U.S. state of Alaska are some of the best fishing grounds anywhere, teeming with salmon and with shellfish such as crab. But a new study, funded by the National Oceanic and Atmospheric Administration (NOAA), says growing acidification of Alaska's waters, particularly those off the southern coast, threatens the state's whole economy − largely dependent on the fishing industry. Research has highlighted the negative effect acidification of oceans can have on marine life,...

The search for survivors: Which species will outlast the rising acidity of oceans?

ClimateWire: Many of the projected effects of climate change on the world's oceans are already visible, such as melting polar ice caps and rising sea levels. But invisible changes may be the most threatening to human food sources, beginning with the tiny species like plankton that inhabit the bottom of the oceans' food chain. As emissions from human activities increase atmospheric carbon dioxide, they, in turn, are modifying the chemical structure of global waters, making them more acidic. Many researchers...

Pacific coral happy as acidity of the ocean rises
2014-01-04 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: COULD corals survive ocean acidification against the odds? That's the hope raised by reefs found to be thriving in naturally acidified waters. Corals use the carbonate ions in water to build their skeletons from calcium carbonate. But ocean acidification caused by climate change reduces the available carbonate ions. Lab studies suggest that this leaves corals unable to grow and survive. The few known reefs living in naturally acidified water also tend to be unhealthy. So Kathryn Shamberger of the...

Increasing Ocean Acidity Harming More Than Just Corals
2013-12-25 15:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: The chemistry of the oceans is changing. And it isn't just the corals and the baby oysters that are unhappy. It makes juvenile rockfish really anxious, and it upsets the digestion of sea urchins. The pH (a measure of acidity -- the lower the pH, the more acid the water) of the planet's oceans is dropping rapidly, largely because the carbon dioxide levels in the atmosphere are increasing. Since carbon dioxide dissolves in water to form carbonic acid, the seas are responding to global change. The...
