The coming death of the oceans : Comments

By Don Aitkin, published 30/1/2015

'Reconsidering Ocean Calamities' is by Carlos Duarte and seven others, most of them Australian, and it is thought important enough for Nature to have devoted an editorial to its message.

Ocean Acidification - Carbon dioxide dissolving in the oceans has lowered pH by 0.1 units since 1750, representing a 30% increase in hydrogen ion (acid) concentration.

Leo Lane, it's not "dishonest climatese" at all. AFAICT there has NEVER been any attempt by any climate scientist in the world to imply that the oceans are turning more acidic than pure water! It's just that anyone who understands chemistry better than year 11 high school level has a more detailed understanding of what "acid" means than you do. I think most scientists would regard decreasing pH as synonymous with "acidification".

Hasbeen, you claim an observed phenomenon to be impossible and you tell my I'm making a fool out of MYSELF?!?!?

The buffering is itself part of the problem, because a lot of marine creatures have shells of aragonite, which is a more soluble form of calcium carbonate than the calcite which is more prevalent in limestone.

All things being equal, a hotter ocean would hold less CO2. But all things are not equal. The rise in atmospheric CO2 concentration was much bigger than the rise in sea temperature, and has had a much greater effect on the amount of dissolved CO2.

Why do you cherry pick facts that superficially suit your position instead of looking at all the facts and adjusting your position accordingly?

It is interesting that a week + prior to NAOO and NASA making the announcement about 2014 temperatures the Japanese Meteorological Agency had already announced 2014 to be the warmest year since records had been taken.
But, regardless of any dispute about temperature, the environment has certainly provided evidence that temperature has been high.

.Iditarod dog sled race travelled over gravel in sections in 2014.
.A lake under the Greenland ice sheet disappeared leaving mushy snow/ice on surface.
.Unprecedented regression of ice in Austfonna, happening over a longer time frame.
.Methane blow outs on Yamal Peninsula.
.There was a spike of heat stroke deaths in Australia in January 2014.
.Children in Alaska made a video in a very creative way of the snow activities they were not able to participate in as usual, due to very little snow just prior to Christmas 2014.

The US Tea Party have resolved that climate change is happening but will not attribute any responsibility by man (2015). They are heavily sponsored by mining interests.
The US Military already believe that climate change is happening and have been making strategic plans for many years to cover the issues.

In regard to acidification, there are areas where impacts are happening. The Bering sea being a prime example of acidification.
Colder shallow waters are more impacted than those close to the equator.

Quote: "The overall message was that ocean acidification is already affecting Alaska waters."
Also: "...Washington’s Blue Ribbon panel that was organized in the Pacific Northwest to address OA after shellfish seed stock crashed due to more acidic waters affecting the hatcheries."

This article flies in the face of the facts.

A look at some graphs will show this.

The first to look at is the temperature graph, which shows a still steadily rising one, and an upward curve.

The second is the link between Co2 and temperatures, both of which are indubitably linked in the irrefutable Graphs.
Currently Co2 is at 400 PPM, unprecedented, and taking us into uncharted territory.

The third would be the solar activity graph, which appears to have peaked during the seventies and is now in a waning cycle.

Suggest you view SBS's years of living dangerously, to see some interesting facts; and indeed, the way some celebs are able to misinterpret or misrepresent them?

Interpretation of the graphs may very, but the graphs don't.

Surely it is past time to stop representing the concerns of the fossil fuel industry; even inadvertently, and time to start looking at those carbon neutral or carbon negative alternatives that will indubitably improve our economic prospects!

Given we stop thinking like a minerals exporter; and instead, think of ourselves as an economy that makes and exports things. And what we need to do to make that happen!?

Arguably, the lowest costing energy on the planet, coupled to the lowest taxing economy on earth, will make that happen and in spades!

Both doable, by #1, moving to thorium and micro-grids, all owned and controlled by the government; and homemade biogas, used onsite via ceramic fuel cells.

And #2, by simply eliminating all the parasites and unproductive practice from the TAX INDUSTRY!

All bound to be resisted to the last breath, by current vested interest.

None of which should alter pragmatic outcomes; such as was the case when we more or less, abandoned our footwear and textiles industries; with far more jobs simply sacrificed on the altar of unavoidable pragmatism!

Leo Lane: It is disappointing that climate fraud still has credence, despite its complete lack of science to support it.

It is indeed disappointing.

Although the carbon tax was axed, the Government still remains party to the fraud, viz. Direct Action implementation; RET retention and subsidisation of unreliable, uneconomic renewable energy; funding the politicised CSIRO's supposed climate research; brainwashing school and university students that climate change is man-made; pledging $200m to the totalitarian UN's world climate fund.

And now there is even the real threat that an ETS would be implemented , should either Malcolm Turnbull or Julie Bishop replace Tony Abbott as Prime Minister.

Raycon stated: " It is disappointing that climate fraud still has credence, despite its complete lack of science to support it."

Please provide properly researched up to date scientific papers that show that anthropogenic climate change is not happening.
As stated in a previous post, there are any number of practical examples showing that there are a number of examples showing that the climate situation is awry.
A further example is drought in the Amazon Basin ; there have been 4 droughts in the last decade. Previously it had been believed a drought in the Amazon Basin is a 100 year occurrance.
Last year there was a photo showing 45,000 walrus on a spit of land instead of hunting as they normally would. Its got something to do with lack of sea ice close to shore and depth of water, Raycon.
Last year the Marshall Islands were overwhelmed by sea water, twice.

Three ski fields in British Columbia; Cyprus, Whistler, Big White have shown a decline in snow since 1901 and an increase in average winter temperatures.

Opinion doesn't match observation, and data collection using instrumentation and satellite data. Opinion is pretty meaningless Raycon, without any objective evidence.
