"Acidification already eating away at tiny creatures along our coast"
Craig Welch | Seattle Times | April 30, 2014
"A year earlier, the ecologist from the Australian Institute of Marine Science had placed this small square near a fissure in the sea floor where gas bubbles up from the earth. She hoped the next generation of baby corals would settle on it and take root.
Fabricius yanked a knife from her ankle holster, unscrewed the plate and pulled it close. Even underwater the problem was clear. Tiles from healthy reefs nearby were covered with budding coral colonies in starbursts of red, yellow, pink and blue. This plate was coated with a filthy film of algae and fringed with hairy sprigs of seaweed.
Instead of a brilliant new coral reef, what sprouted here resembled a slimy lake bottom.
Isolating the cause was easy. Only one thing separated this spot from the lush tropical reefs a few hundred yards away."

"... Here’s why: When CO2 mixes with water it takes on a corrosive power that erodes some animals’ shells or skeletons. It lowers the pH, making oceans more acidic and sour, and robs the water of ingredients animals use to grow shells in the first place.
Acidification wasn’t supposed to start doing its damage until much later this century.
Instead, changing sea chemistry already has killed billions of oysters along the Washington coast and at a hatchery that draws water from Hood Canal. It’s helping destroy mussels on some Northwest shores. It is a suspect in the softening of clam shells and in the death of baby scallops. It is dissolving a tiny plankton species eaten by many ocean creatures, from auklets and puffins to fish and whales — and that had not been expected for another 25 years.
And this is just the beginning..."

On Thursday, April 24, Seattle Times Journalist Craig Welch joins Sarah Cooley of Ocean Conservancy and Ben Strauss of Climate Central for a conversation on how journalists and scientists explain the science behind climate change to the public and share their expertise.
Strauss is vice president for Climate Impacts and director of the Program on Sea Level Rise at Climate Central. He has published multiple scientific papers on sea level rise, testified before the U.S. Senate, authored the Surging Seas report, and led development of the SurgingSeas.org coastal flood risk tool, leading to front-page coverage in The New York Times and The Washington Post and extensive coverage nationwide. He received his Ph.D. in ecology and evolutionary biology from Princeton University.
Cooley is a science outreach manager in Ocean Conservancy's Ocean Acidification program. Previously, she was a research scientist at Woods Hole Oceanographic Institution in Woods Hole, Massachusetts, where her research used oceanographic and social science data to forecast the total consequences of human-driven changes in the marine inorganic carbon cycle. She received her Ph.D. from the University of Georgia School of Marine Programs.
Welch and his colleague Steve Ringman received Pulitzer Center support for "Sea Change: The Pacific's Perilous Turn," their series on ocean acidification for The Seattle Times. The series won the 2013 Scripps Howard Foundation's Edward J. Meeman Award for Environmental Reporting. Welch's first talks @ pulitzer in March 2014 focused on this award-winning reporting.
