Where can I find out more about ocean acidification?

For scientific news, an excellent, constantly updated source is Ocean Acidification, a portal and blog sponsored by the European Project on Ocean Acification. Another excellent source is the PMEL Ocean Acidification site. For basic information, check out the Wikipedia article. Or follow A Sea Change on twitter.

What is “ocean acidification”?

When we think about urgent threats to our environment, the images which come to mind are usually smokestacks and automobiles belching exhaust and smoke into the sky. But much of that pollution–the carbon that billows into the atmosphere from cars, power plants and other smokestack industries–doesn’t stay there. Much of it is absorbed by the […]

What can I personally do to reduce ocean acidfication?

Any action you’d take to reduce release of CO2 in the atmosphere will help. So at home, for example, if your electricity comes from coal-fired plants, turn off unneccessary lights. In some part of the United States, it’s possible to choose where your electricity comes from; you can request that all your power be generated […]

What are the potential long-term consequences of ocean acidification?

Over the next century, steady increases in carbon dioxide emissions and the resulting rise in the acidity of the oceans could cause most of the world’s fisheries to experience a total bottom-up collapse, a state that could last for millions of years. Ocean acidification threatens over 1,000,000 species with extinction–and the protein source for 1 […]

What action is being taken to curb ocean acidification?

So far, not much! Reducing ocean acidification means reducing carbon output. And, as you know, nations are struggling to agree on acceptable levels of greenhouse gas. The upcoming meeting in Copenhagen this December, COP-15, will be a crucial time for all countries to come to grips with the reality of climate change, above and in […]

What about carbon sequestration?

So far, no reliable method has been found for removing excess carbon from the atmosphere, other than dissolving it in the ocean. Which as we’ve just learned isn’t a good idea! A method may be found, but until then, the only solution we know is radically reducing the burning of fossil fuels. Period.

Can the scenario really be this grim? Why haven’t I heard about it before?

Given all of the attention we’re paying to climate change on the earth’s surface, it does seem surprising that this threat has gone relatively unnoticed so long.  Most of us don’t look below the ocean’s surface. As long as we see fish in the supermarket and on our table, we don’t question where they’re coming from. […]

Interview with Elias and Sven

By Daniel de la Calle   Between lemonades, swimming pools and ice cream Sven and Elias sat down for this brief interview, five years after the beginning of A Sea Change:

January 2013

By Daniel de la Callehttp://www.danieldelacalle.com/ Gone is 2012, the hottest or coldest year in recent history depending on where you live, gone too are the days of Ocean Acidification information famine.  You can now watch videos deciphering the oceans, listen to songs about acidity, follow via tweets a research expedition to Antarctica, attend a seminar […]

100 Screenings in Chile

By Daniel de la Calle About a year ago I traveled with our documentary to Chile for a series of screenings in Santiago, Valparaiso and Puerto Montt.  While in Valparaiso I had the chance to meet with some of the local Natural History Museum staff, under renovation at the time.   They liked the film for […]

13 News for the 31st

By Daniel de la Calle Three years ago you really needed to scrape at the bottom of the barrel to come up with news on the web about Ocean Acidification.  Today I am “only” posting 13 items and have to leave at least 10 more out: ≈≈≈≈64% of the waters existing outside national jurisdiction, the […]

Late February, Late Winter News

By Daniel de la Calle We cannot let the month end and watch the season slowly fade out without a postful of links, videos, news and photos on Ocean Acidification: »The Oceanography Laboratory at Villefranche-sur-Mer (France) is deploying nine “mesocosms” (52 m3) over a 30 days period in order to cover the range of pCO2 […]

400 Blows

By Daniel de la Calle 400 blows do not raise hell after all: This month of May 2013 will be remembered as the time when we passed that 400ppm line of CO2 concentration in the atmosphere.  The media often uses the crossing of such a round, numeric Rubicons to begin global campaigns and to instigate […]

Marching Through March

By Daniel de la Calle March 2013 is furiously peeling off days from the calendar, desperate to pass the torch on to other months, other seasons.  Time these days feels radically non-linear, we better post some news about the oceans and acidification this very day: •According to a new paper published in Nature Geoscience predators […]

Not Only Ocean Acidification

By Daniel de la Calle ≈≈≈Marine researchers from around the world are in Cairns, Australia, this week for the 12th International Coral Reef Symposium (July 9-13): “From Cairns, 2,600 scientists have signed a Consensus Statement on Climate Change and Coral Reefs.
The consensus statement calls for a worldwide effort to overcome growing threats to coral ecosystems […]

A Hard Nut

By Daniel de la Calle Open your mouth and repeat after me: “SA-PU-CA-IA!” I know a month and a half ago I posted what was to be my last text on the blog, but these things happen constantly and if politicians make a living of it I too am fully entitled to say one thing […]

Overflow

By Daniel de la Calle How much is too much?  When does a stream of information flow over and one more entry, article, news piece or documentary simply becomes redundant, numbing white noise, counterproductive annoyance? Searching online today, the 12th of April of 2013, for the term Ocean Acidification brings up 1.900.000 pages.  Little compared […]

After the Storm

By Daniel de la Calle The storm passed and so did the election, strangely intertwining both in a way that made hard to distinguish one from the other.  In a world steamrolling to global weirding certain people call a late October hurricane in Manhattan “the new normal”.  For some absurd reason such a catchphrase has […]

All Seas: INDIAN OCEAN

By Daniel de la Calle Simon Reeve’s six-episode series titled Indian Ocean delivers a kaleidoscopic view of the world’s third largest body of water, the one least studied by scientists.  Starting in South Africa and ending in Australia, passing through rocky cliffs in Oman and the endless beaches of Orissa, each episode hides, disguised in the […]

Sex! (A.K.A. News)

By Daniel de la Calle Media Matters for America (by “America” they mean the USA) released a study last week showing the “Kardashians get 40 times more news coverage than Ocean Acidification”, which was great news for the Kardashians, for Ocean Acidification and for me. For me because I finally got to see some pictures […]

Art&facts

By Daniel de la Calle For more than 35,000 years we have been inspired by nature, driven to reproduce and depict it in drawings, carvings, photography or film.  That original motivation might have been shamanistic, triggered by a dependence on other species for survival, but in many cases there are also unquestionable examples of our […]
