World’s oceans in ‘shocking’ decline

Warns Richard Black at the BBC.

The oceans are in a worse state than previously suspected, according to an expert panel of scientists.

In a new report, they warn that ocean life is “at high risk of entering a phase of extinction of marine species unprecedented in human history”.

They conclude that issues such as over-fishing, pollution and climate change are acting together in ways that have not previously been recognised.

The impacts, they say, are already affecting humanity.

The panel was convened by the International Programme on the State of the Ocean (IPSO), and brought together experts from different disciplines, including coral reef ecologists, toxicologists, and fisheries scientists.

Call me a cynic, but I no longer take claims about ‘expert panel of scientists’ at face value. Sadly, Richard Black of the BBC does. (more…)

Numbers watch

by John Brignell

The way to bring down a modern state is to attack its energy, manufacturing and transport systems, hence the dam busters and the bombing of German railways and factories during the Second World War. Nowadays, however, developed nations are under attack from the Enemy Within, the neo-Marxist Greenies. Greenpeace, which in its inchoate form was a fairly straight environmental campaigning group, was soon taken over by political extremists and after its conversion to an apocalyptic vision lost original members such as Patrick Moore; but over time this has also happened to other mainstream parties. The UK is the world basket case in this respect (witness the passing without comment of the destructive carbon tax, which is being strongly resisted in other western countries) and almost the entire British political class have become true believers. Nevertheless, countries far apart in both distance and character, such as Australia and Germany , are manoeuvred relentlessly by their green parliamentary minorities in the direction of economic suicide.

Carbon Dioxide and Earth’s Future: Pursuing the Prudent Path

by Craig and Sherwood Idso

Special Issue
This week we announce the release of our newest major report, Carbon Dioxide and Earth’s Future: Pursuing the Prudent Path. Based on the voluminous periodic reports of the Intergovernmental Panel on Climate Change (IPCC), the ongoing rise in the atmosphere’s CO2 concentration has come to be viewed as a monumental danger — not only to human society, but to the world of nature as well. But are the horrific “doomsday scenarios” promulgated by the climate alarmists as set-in-stone as the public is led to believe? Do we really know all of the complex and interacting processes that should be included in the models upon which these scenarios are based? And can we properly reduce those processes into manageable computer code so as to produce reliable forecasts 50 or 100 years into the future? At present, the only way to properly answer these questions is to compare climate model projections with real-world observations. Theory is one thing, but empirical reality is quite another. The former may or may not be correct, but the latter is always right. As such, the only truly objective method to evaluate climate model projections is by comparing them with real-world data.

NGO pleads for $15 billion “ocean acidification” monitoring system

by Anthony Watts

Via Eurekalert, from the NGO Partnership for Observation of the Global Oceans (POGO), a press release that says, “panic! please send money”. Here’s the punch line:

The Foundation says the average level of pH at the ocean surface has dropped from 8.2 to 8.1 units, “rendering the oceans more acidic than they have been for 20 million years,”

Note that any pH lower than 7.0 is considered “acidic”. Distilled (pure) water has a pH of 7.0. Right now the ocean with a pH of 8.1 is considered “basic”. (more…)

Ocean Acidification Database

Wednesday, September 22nd, 2010

Source: http://www.co2science.org/data/acidification/acidification.php


Results and Conclusions
In what follows, we present several graphics that help one better discern the major message and sub-messages of the data contained in our Ocean Acidification Database. These figures will be updated periodically, as the number of records in the database grows and as time permits us to redo the various analyses upon which the figures are based.

We begin by plotting in Figure 1 the percent changes in all five of the major life characteristics included in this study (calcification, metabolism, growth, fertility and survival) as functions of experimentally-orchestrated declines in seawater pH from the presently prevailing value, where each entry in our Ocean Acidification Database is represented by its own individual data point.

Climate: The Counter Consensus by Robert M. Carter
(Stacey International, 2010)

Bob Carter is a member of a small group of Australian scientists (although he was born in the UK and mostly educated in New Zealand) who, having attained a distinguished position in their disciplines (he is a paleo-climatologist), were willing to put their reputations on the line by speaking out against the most extraordinary fraud in the history of Western science: the fantasy that by controlling anthropogenic emissions of carbon dioxide, mankind can control global temperatures; a miraculous global thermostat.

This fantasy is so bizarre that Jonathan Swift could, using statements from today’s Royal Society without embellishment, write them into his account of the kingdom of Laputa. The citizens of Laputa lived on a cloud and threw rocks at rebellious surface cities beneath them. Using Laputa as a satire on the Royal Society, Swift portrayed the ruin brought about by the attempts by the scientists living in the clouds to impose their will on the helpless people living below them.

Bob Carter’s book is a well written account of the deep corruption of our scientific inheritance which has been central to the spread of this fantasy. It is a fantasy which has spread throughout the intellectual, political and religious elites of the English-speaking world, and which has infected key Australian institutions, notably the CSIRO, the Australian Bureau of Meteorology, and virtually all our universities.

Ocean Acidification (Effects on Marine Plants: Phytoplankton, Foraminifera) — Summary

Tuesday, July 20th, 2010

Source:  CO2 Science

Foraminifera are amoeboid protists with reticulating pseudopods, i.e., fine strands of cytoplasm that subdivide into branches that merge to form a dynamic network. They are typically less than one mm in size (but can be much larger), and they produce an elaborate calcium carbonate shell called a test, which may have one or more chambers. As for their impact on the undersea marine environment, these widespread calcifying protozoa, acording to Schiebel (2002), are responsible for 32-80% of the global deep-ocean flux of calcite. Therefore, it is important to determine the degree to which various forams — as they are often called — may or may not be harmed by likely future increases in what has come to be known as ocean acidification.

Ocean Acidification (Effects on Marine Plants: Phytoplankton — Coccolithophores) — Summary

Wednesday, June 16th, 2010

Source: CO2 Science

Coccolithophores are single-celled algae and protists that contain chlorophyll, conduct photosynthesis, and possess special plates or scales known as coccoliths that they produce by the process of calcification. They are found in large numbers throughout the surface euphotic zones of the world’s oceans; and we here review the results of several studies that indicate how they may fare in a CO2-enriched world of the future that is characterized by significantly altered oceanic carbonate chemistry.

Working with two previously untested coccolithophores, Calcidiscus leptoporus and Coccolithus pelagicus, which they describe as “two of the most productive marine calcifying species,” Langer et al. (2006) conducted batch-culture experiments in which they observed (1) a “deterioration of coccolith production above as well as below present-day CO2 concentrations in C. leptoporus [italics added],” and (2) a “lack of a CO2 sensitivity of calcification in C. pelagicus” over an atmospheric CO2 concentration range of 98-915 ppm, both of which observations, in their words, “refute the notion of a linear relationship of calcification with the carbonate ion concentration and carbonate saturation state.” (more…)

Effects of Elevated CO2 and Temperature on a Temperate Coral

  • Rodolfo-Metalpa, R., Martin, S., Ferrier-Pages, C. and Gattuso, J.-P. 2010. Response of the temperate coral Cladocora caespitosa to mid- and long-term exposure to pCO2 and temperature levels projected for the year 2100 AD. Biogeosciences 7: 289-300.

Rodolfo-Metalpa et al. (2010) write that “anthropogenic CO2 emitted to the atmosphere is absorbed by the oceans leading to decreases in pH, CO32- concentration, and the related CaCO3 saturation state (O) of seawater,” and that “as a result, coral calcification is expected to decline dramatically in the future, raising widespread concerns about the future of our oceans in a high-CO2 world (e.g. Hoegh-Guldberg et al., 2007).”

Investigating the effects of this projected decline, Rodolfo-Metalpa et al. collected three live colonies of Cladocora caespitosa in the Bay of Villefranche (Ligurian Sea, France) at about 25 meters depth in July 2006 plus three other colonies in February 2007. They divided the colonies into fragments and carefully removed single polyps that they attached to PVC plates and randomly assigned to aquariums that were continuously supplied with unfiltered seawater and maintained at ambient or elevated water temperature (T or T + 3°C) in equilibrium with air of ambient or elevated CO2 concentration (400 or 700 ppm), subjecting them to “(1) mid-term perturbations (1 month) in summer and winter conditions of irradiance and temperature, and (2) a long-term perturbation (1 year), mimicking the seasonal changes in temperature and irradiance.” (more…)

Ocean Acidification: How Bad Can it Get?

In a special issue of Oceanography published in December of 2009, Feely et al. review what we supposedly know about the current pH status of the world’s oceans, as well as what they say we can likely expect by the end of the current century.

Getting right to the crux of the matter, the three researchers write in their abstract that “estimates based on the Intergovernmental Panel on Climate Change business-as-usual emission scenarios suggest that atmospheric CO2 levels could approach 800 ppm near the end of the century,” and that “corresponding biogeochemical models for the ocean indicate that surface water pH will drop from a pre-industrial value of about 8.2 to about 7.8 in the IPCC A2 scenario by the end of this century.” And, of course, they warn that, as a result, “the skeletal growth rates of calcium-secreting organisms will be reduced,” ending with the obligatory statement that “if anthropogenic CO2 emissions are not dramatically reduced in the coming decades, there is the potential for direct and profound impacts on our living marine ecosystems.”

Well that’s Feely et al.’s story; but in the very same issue of Oceanography — in the article that appears just before their paper, in fact — NOAA’s Pieter Tans presents a much different take on the subject. (more…)

Answer to a “global warming” fanatic

Sunday, February 21st, 2010

From The Viscount Monckton of Brenchley

  • I try to answer as many enquiries as I can from people who want to discuss “global warming”. I wrote this letter in reply to a “global warming” fanatic who, it is not unfair to say, had never actually thought about the superstition to which he subscribes. Perhaps this letter will make him think a little more and believe a little less.

Dear Enquirer, – Thank you for taking the trouble to write to me. If I may, I shall highlight various passages from your letter in bold face, and then respond to them seriatim in Roman face.

“I am not a climate scientist, and so I can only go by the overwhelming consensus amongst scientists that man-made climate change is occurring and that it poses a grave threat to humanity.” (more…)

Scarewatch: Schneider again.

Thursday, January 14th, 2010

From The Viscount Monckton of Brenchley

The desperation of the climate extremists as global temperatures plummet for the tenth year in a row is growing. Stephen Schneider, professor of environmental biology and “global change” at Stanford University, said today:

  • “We can no longer prevent global warming — it is upon us. Rapidly melting polar icecaps, acidification of the oceans, loss of coral reefs, longer droughts, more devastating wildfires, and sea level rise that threatens island nations and seacoasts everywhere are clear signs of change in Earth’s climate. Disruptions of the monsoon seasons in India and China already threaten crop yields resulting in more frequent and severe food shortages than in the recent past … If we continue ‘business as usual’ our habitat could be disrupted beyond recognition, with consequences for our way of life that we cannot now foresee. Without vigorous and immediate follow-up to the Copenhagen conference and well-conceived action we are all threatened by accelerating and irreversible changes to our planet.”

Nonsense. Here’s why. (more…)

CO2 Benefits Marine Life

A new research paper by Dr. Craig Idso, author of the 2009 book, CO2, Global Warming and Coral Reefs: Prospects for the Future, exposes the flimsy science behind a recent National Resources Defense Council film claiming carbon dioxide is destroying the world’s oceans.

The research paper, “Acid Test: The Global Challenge of Ocean Acidification,” documents extensive scientific evidence that human emissions of carbon dioxide are not poisoning the oceans to the detriment of marine invertebrates or other marine life. To the contrary, the paper shows that “even a cursory review of the peer-reviewed scientific literature reveals … that the ongoing rise in atmospheric CO2 concentration will actually prove a boon to calcifying marine life.” [emphasis in the original] (more…)
