A Sea Change: Imagine a World without Fish — ocean acidification film — premiers tonight on Planet Green

Global warming is “capable of wrecking the marine ecosystem and depriving future generations of the harvest of the seas” (see Ocean dead zones to expand, “remain for thousands of years”).

A new documentary on ocean acidification is airing tonight (Saturday) on Planet Green at 8 pm.  (You can find your Planet Green channel on their website.)  Here’s the trailer:

For more on the subject with links to primary sources and recent studies, see “Imagine a World without Fish: Deadly ocean acidification “” hard to deny, harder to geo-engineer, but not hard to stop “” is subject of documentary.”

    As carbon dioxide builds up in the atmosphere, a large fraction has dissolved into the ocean, increasing the total amount of dissolved inorganic carbon and shifting seawater chemistry toward more acidic conditions. Since the end of the last century, the amount dissolved CO2 gas [CO2 (aq)] has increased because of both the rise in inorganic carbon levels and acidification. Simultaneously there is a decrease in the water’s pH, indicating rising acidity, and a decrease in the carbonate ion ([CO3 2- ], the substance that many marine animals use to build their shells.

    Stanford, CA. In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria [1976] by mid-century if emissions are not dramatically curtailed now. This is the first recognition that atmospheric CO2 emissions will cause ocean waters to violate EPA water quality criteria.

    In addition to acidification, there is also the problems of other contaminants (mercury, etc.). They will many many commercial species eventually inedible.

    We need an environmental strategy like the one at:

    A Strategy for Carbon Emissions, Renewable Energy, Toxic Contaminants, and Conservation

    It is capable of addressing most environmental issues.

    A Cap-and-Trade Alternative

    This is off topic, but I though you might want to blog on the “Worldwide Views On Global Warming” event that took place earlier today at some 40 locations around the world, with five in the U.S.

    Each location had about 100 citizens involved, so more than 4000 views were collected and tabulated, to be shared with delegates at the climate talks in Copenhagen. Initial results are available on the web at

    The Danish Board of Technology organized the sessions. I found the activity and results encouraging: most participants agreed that our leaders should be dealing with climate change much more aggressively.

    A common theme that emerged from the discussions (but that wasn’t covered in the tabulated questions) was that governments should be doing much more than they are to educate the public about climate change and its consequences. Education would lead to more action!
