..:: “Phytoplankton produce more oxygen than all plant life on earth vital in maintaining the earth’s atmosphere. They are also the organisms most likely to be affected by global warming and climate change.
..:: Fish species will be threatened by increasing acidity ( – pH) through acidosis, which is a buildup of carbonic acid in body fluids leading to death. Hyper-capnia, or excessive carbon dioxide in the blood, threaten fish species of the future. A study concluded that elevated levels of carbon dioxide can result in high levels of mortality for amberjack and halibut.
A recent study concluded that decreases in ocean pH by 0.5 units or more may severely disrupt the internal acid-base balance of sea urchins, which can ultimately result in their death.
Cephalopods such as squid might be particularly affected by increased oceanic carbon dioxide because they require very high amounts of oxygen supply to the blood to sustain their energy-demanding method of swimming. Lower levels of pH can impair oxygen supplies in these species, reducing oxygen capacity by about 50 percent with a pH decrease of 0.25 units.
..:: as the ocean loses its ability to absorb carbon dioxide, its ability to regulate our global climate and supply oxygen will falter, resulting in reduced breathable oxygen….
..:: Ocean Acidification and the Effects to Open Ocean and Coastal Ecosystems Presentation by Dr. Richard Feely, AGU Fellow and Supervisory Oceanographer at the NOAA Marine Environmental Laboratory.
..:: With NOAA under the dept of “commerce”… how can we expect anything but “business” as usual….
..:: “Ocean Acidification is now irreversible during our lifetimes…
It will take tens of thousands of years for ocean chemistry to return to a condition similar to that occurring at pre-industrial times (about 200 years ago)….
Our ability to reduce ocean acidification through artificial methods such as the addition of chemicals is unproven. These techniques will at best be effective only at a very local scale, and could also cause damage to the marine environment…
Reducing CO2 emissions to the atmosphere is the only practical way to minimize the risk of large-scale and long term changes to the oceans…
..:: “For all practical purposes in our lifetime… Ocean Acidification is “permanent”, Emerson said.
..:: A San Francisco environmental group, the Center for Biodiversity, has asked 10 states — Washington, Oregon, California, Alaska, Hawaii, Florida, New York, New Jersey, Maine and Delaware — to declare their coastal waters “impaired” under the Clean Water Act because of rising acidity. Such a move could clear the way for the states to regulate carbon-dioxide emissions.
“Though the SCIENCE is there, the “political will” is NOT there,” said Miyoko Sakashita, a lawyer for the Center for Biodiversity. “At least this will raise awareness among policymakers.”
Though cuts in carbon dioxide and other greenhouse-gas emissions might slow or reverse global warming, scientist say it could take thousands of years or longer to reverse the increased acidity of the oceans.
“For all practical purposes in our lifetime… Ocean Acidification is “permanent”, Emerson said.
..:: The report, in Science magazine, brings together dozens of studies that collectively paint a dismal picture of deteriorating ocean health.
..:: “This is further evidence we are well on our way to the next great extinction event,” said Ove Hoegh-Guldberg, the director of the Global Change Institute at the University of Queensland in Australia and a co-author of the report.
New research shows oxygen depletion in the atmosphere accelerating since 2003, coinciding with the biofuels boom; climate policies that focus exclusively on carbon sequestration could be disastrous for all oxygen-breathing organisms including humans Dr. Mae-Wan Ho
If we don’t change our direction… surely we will end up where we are headed… ~Chinese Proverb
It is no measure of health to be well adjusted to a profoundly sick society. ~Krishnamurti
It is not only for what we do that we are held responsible, but also for what we do not do. ~Moliere
Never be afraid to do what’s right, especially if the well-being of a person or animal is at stake. Society’s punishments are small compared to the wounds we inflict on our soul when we look the other way.

… The Oceans are absorbing One Million TONS of CO2 PER HOUR from the atmosphere ….
Ocean Acidification combined with worldwide industrial toxic dumping into rivers is killing the only Living Oceans in the universe…
Without Living Oceans, planet Earth will no longer have a Life supporting atmosphere…
Consider this scenario, and tell me if i am wrong…
1) we have no way to stop runaway Ocean Acidification…
2) we will probably continue burning fossil fuels worldwide for about 50 more years…
3) all the kings horses and all the kings scuba divers can not prevent the Oceans from becoming so acidic it will dissolve the coral reefs and impair all marine life, including the phytoplankton….
4) when that happens… we could loose up to 70% of Earth’s oxygen supply…
5) with more CO2 in the atmosphere, even the trees, plants and crops will no longer function…
6) when the methane hydrates melt… and they already are… mega tons of flammable biomass will burn out of control worldwide… releasing additional greenhouse gas, increasing the positive feedback loop….
7) forests will become deserts… further reducing oxygen and increasing CO2…
Earth’s currently Livable atmosphere will be lost for thousands of years… No blue, No green… see: http://ecodelmar.org/sylvia/
… we LIVE on such a beautiful planet… if we could just share the biosphere and stop destroying LIFE for profit …
… and so many people are saying… well… humans had their turn on Earth… so now “mother nature” will just take back the planet… and “shake us humans off”… like a bunch of fleas…
… i don’t understand how intelligent humans can have this “attitude”… that we “got ours”… and we had “our fun” …
… and so many scientists that i talk to have this exact attitude…
… they say “so what” … let “mother nature” take back the planet… to heck with the future generations…
… i say … do you not realize that future generations are as much a part of “mother nature” as you and i are right now…
… how can anyone be so egotistically arrogant as to say “so what if humans become extinct”… i ask you now if you think LIFE is so worthless for “tomorrow’s children”… if you HONESTLY think LIFE is really that “worthless”… would you bite off even the tip of your own tongue, right now… throw it in the air… and tell God how “worthless” it was for you… and how worthless future generations are to you…
