Ocean studies

[wirebender]

Here chicken littles. A paper recently published in Nature showing the ocean to be presently more alkaline than it has been in the past 250 million years.

http://pages-142.unibe.ch/science/scor/gfx/Ridgwell&Schmidt2010NGeo-PastOceanAcidification.pdf

The paper clearly shows a mean ph of 7.7 over the past 250 million years and the envirowackos are saying that if we don't obey, the ph of the oceans is going to drop to 7.88.

Ocean acidification was a hoax. You can relax and move on to the next fabricated crisis.

Just another study that points out that we are rapidly approaching the point where our actions will have direct affects on our ability to provide food for our present population.

Just a bunch of scientists, and what the heck do they know?

We are having a tremendous effect on the earth.

We certainly do at the local level. But not globally. That is thankfully still beyond mans power.

LOL!!! The skeptics have the nerve to call "warmism" a religion?!?! What greater act of faith can we have than the comment I put in BOLD?

We don't call it a religion. You all have made it so. AGW exhibits every characteristic of a religion. That's not our fault!

It isn't just us "deniers" that call it a religion. Courts have also ruled that it is a religion.

Its not about the climate. Its about overharvest. Anyone come up with a study that doesnt support overharvest? Look at the wild salmon returns. Sad. But heck we can buy them from china. Those farm raised cess pool water farms. Cool. When it comes to profit vs anything, profit always wins.

The second they mentioned acidification they lost all credibility.

The second that you claimed to have an education as a geologist you lost all credibility. So you are supposed to be smarter than the scientists that publish for the National Academy of Science.

Abstract
Ocean acidification represents a key threat to coral reefs by reducing the calcification rate of framework builders. In addition, acidification is likely to affect the relationship between corals and their symbiotic dinoflagellates and the productivity of this association. However, little is known about how acidification impacts on the physiology of reef builders and how acidification interacts with warming. Here, we report on an 8-week study that compared bleaching, productivity, and calcification responses of crustose coralline algae (CCA) and branching (Acropora) and massive (Porites) coral species in response to acidification and warming. Using a 30-tank experimental system, we manipulated CO2 levels to simulate doubling and three- to fourfold increases [Intergovernmental Panel on Climate Change (IPCC) projection categories IV and VI] relative to present-day levels under cool and warm scenarios. Results indicated that high CO2 is a bleaching agent for corals and CCA under high irradiance, acting synergistically with warming to lower thermal bleaching thresholds. We propose that CO2 induces bleaching via its impact on photoprotective mechanisms of the photosystems. Overall, acidification impacted more strongly on bleaching and productivity than on calcification. Interestingly, the intermediate, warm CO2 scenario led to a 30% increase in productivity in Acropora, whereas high CO2 lead to zero productivity in both corals. CCA were most sensitive to acidification, with high CO2 leading to negative productivity and high rates of net dissolution. Our findings suggest that sensitive reef-building species such as CCA may be pushed beyond their thresholds for growth and survival within the next few decades whereas corals will show delayed and mixed responses.

Abstract
Atmospheric carbon dioxide concentration is expected to exceed 500 parts per million and global temperatures to rise by at least 2°C by 2050 to 2100, values that significantly exceed those of at least the past 420,000 years during which most extant marine organisms evolved. Under conditions expected in the 21st century, global warming and ocean acidification will compromise carbonate accretion, with corals becoming increasingly rare on reef systems. The result will be less diverse reef communities and carbonate reef structures that fail to be maintained. Climate change also exacerbates local stresses from declining water quality and overexploitation of key species, driving reefs increasingly toward the tipping point for functional collapse. This review presents future scenarios for coral reefs that predict increasingly serious consequences for reef-associated fisheries, tourism, coastal protection, and people. As the International Year of the Reef 2008 begins, scaled-up management intervention and decisive action on global emissions are required if the loss of coral-dominated ecosystems is to be avoided.

Is any AGW supporter ever going to answer this question?

If the promoters of man-made climate fears truly believed the "debate is over" and the science is "settled", why is there such a strong impulse to shut down debate and threaten those who disagree?​

Coral Reefs Under Rapid Climate Change and Ocean Acidification

Guess no one told them that the oceans are presently the most alkaline that they have been in the past 250 million years. The mean for the past 250 million years has been 7.7. Less alkaline than the present. Ocean acidification is a hoax old rocks. Just one more of many. What do you suppose the next crisis will be?

I prefer actual data. Your pronouncements don't hold much H2O!!!

Is there one single lab experiment that demonstrable how a 500PPM CO2 atmosphere raises temperature .2 degrees much less 2 degrees?

No. I didn't think so

That's been discussed repeatedly. We know it absorbs IR. The rest is logic, obviously not your strong suit.

 

[Old Rocks]

Nothing involving thinking or logis is Franky boys strong suit.

Roxy negged me for this post.

Obviously, he can't answer the question.

The warmyalarmysmarmy types abandoned logic a loooooonnnnnngggg time ago konrad. Try again.

I linked above to a brand new published study konradv. They stated quite clearly that the average mean for the past 250 million years was 7.7 amd you are in a hand wringing panic over the threat of it dropping to 7.88? Don't you read?

 

[Old Rocks]

Bentwire, old boy, why don't you try breathing what the average atmosphere for the earth is, the average for all 5 1/2 billion years?

The rest is called real science, Dear. And you fail.

 

[CrusaderFrank]

You still haven't even stated a hypothesis.

And you can't show how a 500PPM CO2 atmosphere raises temperature 2 degrees.

Already been through that rocks. I wouldn't have any problem at all breathing it and neither would any of the rest of us. We would do just fine. The belief that O2 didn't appear in a gas form till about 2.2 billion years ago is going the way of the dinosaurs rocks. New research is shedding new light. Read something besides your handwringing envirowacko publications.
