Lots of buzz about a hot, new documentary film A Sea Change which is about ocean acidification and its potential to empty the oceans of fish. I haven’t seen the film although I had a chance to at a seafood conference in San Diego last month but couldn’t face a visual version of a topic I’ve written about since 2006. I have enough trouble sleeping as it is…
Turns out the filmmakers got the idea to make the film by ‘googling’ “ocean acidification” in Nov 2006 and found very few entries. I guess my 2006 articles were among the first-ever articles published about ocean acidification and how climate change is a major threat to the global oceans. — Stephen

Ailing Reefs Face New Threat of Acidity
By Stephen Leahy
Climate change is making the world’s oceans more acidic, seriously endangering marine ecosystems, including coral reefs.
Carbon dioxide emissions from the burning of fossil fuels have already made the oceans 30 percent more acidic than they have been in millions of years, according to a new report by leading scientists. And the rate of acidification is accelerating as the oceans absorb more than two billion tonnes of carbon each year from the atmosphere.
“This is a dramatic change in the world’s oceans, a change that marine organisms have never dealt with before,” said Joan Kleypas, the report’s lead author and a scientist at the National Centre for Atmospheric Research (NCAR) in Boulder, Colorado.
“The oceans have changed and they are becoming more acidic. There is no debate about this,” Kleypas told IPS. Continue reading
