As the amount of atmospheric carbon dioxide continues to rise, our oceans are playing an increasingly important role in absorbing some of this excess. In fact, it was reported recently that the global ocean annually draws down about a third… Read More ›
“We were alarmed to find that diatoms were so negatively affected, with some species likely to have diminished silica production before the end of this century,” says Dr Petrou.
Human actions have already increased carbon on the planet by about 40 percent. A quarter of that goes into the ocean. And the ocean has decreased by about .2 pH units, which may not sound like a lot. But, pH is a logarithmic scale like the Richter scale. So .2 pH is about 30% more acidic than it was before the Industrial Revolution.
… as climate change alters the chemistry of the world’s oceans, scientists and fishermen are just beginning to understand how this economically, culturally, and ecologically important species will be impacted.
“Oregon is ground zero for ocean acidification impacts–the water chemistry off our coast is already changing and has changed dramatically. For a glimpse into the science, the impacts and the information gaps behind ocean acidification in Oregon, check out the… Read More ›
Though the tide can’t be totally turned back, the report, “Major Findings, Recommendations, and Actions,” found ways to blunt the environmental and economic impact now.
