A guess is no help to knowing

A paper published in Nature on 10 February 2013 could destroy the global warming scare.

It’s called Atmospheric verification of anthropogenic CO₂ emission trends and the Abstract is available on our side of the paywall, along with the Supplementary Information. However, I’ve also obtained a copy of the paper (800 KB) and it’s fascinating. There’s a larger version (3 MB), not so heavily compressed and less murky. Read more… »

It has been discovered that Australian coal has a magical property – it is one of a small group of coals which produce an invisible gas with supernatural properties.

This magic gas, carbon dioxide, first became famous for its claimed ability to warm the whole world, thus removing the threat of a new ice age. The British academic who reported this magic power claimed that winter snow would become “a very rare and exciting event.”

Then an Australian guru predicted that just a tiny addition of magic gas to the atmosphere would abolish floods, and billions of dollars were spent constructing water desalination plants to combat his forecast of never-ending droughts. Read more… »

It’s widely agreed that burning petroleum and other hydrocarbons is steadily increasing the atmospheric level of carbon dioxide. There are suspicions there could be other causes, because the rise in CO2 doesn’t reflect the hydrocarbon usage curve, which shows a lot more variability. But, still, the conventional opinion deprecates the use of “fossil” fuels because increased CO2 will cause dangerous climatic changes (global warming). However one also reads that more CO2 is making the Earth greener — more CO2 means plants are growing faster and larger. This article by Matt Ridley in the WSJ a week ago (rerun at GWPF) mentions two further reasons to thank the use of hydrocarbons — it saves trees and gentle warming boosts plant growth. — Richard Treadgold

How Fossil Fuels Have Greened The Planet

Matt Ridley

This is an adopted article.

Did you know that the Earth is getting greener, quite literally? Satellites are now confirming that the amount of green vegetation on the planet has been increasing for three decades. This will be news to those accustomed to alarming tales about deforestation, over-development and ecosystem destruction.

This possibility was first suspected in 1985 by Charles Keeling, the scientist whose meticulous record of the content of the air atop Mauna Loa in Hawaii first alerted the world to the increasing concentration of carbon dioxide in the atmosphere. Read more… »

Here’s an interesting reflection on the climate system which at a stroke highlights the complexity of climate and puts to one side (at least for a moment) the belief that it must have a single controller, such as a minor atmospheric gas.

Dr Vincent Gray explained today:

The idea that the Earth has a “radiation budget” is inherently wrong.

The climate is a heat engine. The energy comes in from the sun. The exhaust goes out to space.

The exhaust must be less than the input because in between some work must be done. This would include maintenance of all living creatures plus erosion and other changes in the surface.

A scientist comments that the concept of a budget is both sound and useful, even if not strictly applicable all of the time. The energy budget approach is at the heart of modern climatology and is not controversial.

I wonder if any papers have addressed the total work done by the climate system? Read more… »

Why Bury the Essentials of Life
in Carbon Cemeteries?

To the Editor
Climate Conversation

3rd August 2012

We are told that carbon dioxide is such a dangerous gas that we must capture and “bury it deep down below”.

Carbon is the building block for every bit of organic matter on earth – bread, butter and bitumen; coal, cauliflowers and cows; men, microbes and mulberries.

When oxidised by combustion in fires and engines, or digested in stomachs, or decayed in soil or compost, every bit of organic matter is recycled into the harmless natural atmospheric gas, carbon dioxide. Plants extract this plant food from the atmosphere, reuse the carbon, and recycle the oxygen for use by all forms of animal life.

Every tonne of coal burnt produces about three tonnes of carbon dioxide containing over two tonnes of oxygen and under one tonne of carbon. Thus with every tonne of carbon buried, more than twice as much life-sustaining oxygen must also be sacrificed. Read more… »

When the Herald reported that an “‘Abrupt increase’ in CO2 absorption slowed global warming” the first question it raised was what sort of increase was an extra “one billion tonnes of carbon per year”. It said:

The earth would have warmed faster in the last two decades had there not been an unexplained rise in the amount of carbon dioxide being absorbed on land, scientists believe.

Fortunately, Jo Nova and David Evans have commented. David describes the billion tonnes of carbon as insignificant. Jo mocks the implication that our selfish warming would have been worse without this previously unknown factor. Read more… »

An unimaginable proposal

“As a result — and for reasons that remain unexplained — the waters of the Southern Ocean may have begun to release carbon dioxide.”

Scientific American makes the most illogical statement I’ve heard in a while.

If there’s no reason for this event, why would one propose it?

An event is proposed for which no cause can be imagined. The author proposes something he has no reason to believe — or proposes something but can’t imagine why. This is nuts. It’s not science. Read more… »

Big things influence little things. Little things hardly at all influence big things.

Please bear this in mind when the topic of climate comes up. Let me elaborate.

In the fourth form, little boys do not push big fat boys around and taunt them with “who’s a mummy’s boy, then?” The big fat boys pick on the little boys instead. It just seems more natural.

Among animals, rats don’t eat live caribou, lizards leave lions alone and hamsters don’t munch bears.

Any animal meeting a tiger fears for tomorrow, and an animal near enough to a lion to distinguish its nose hairs wishes it couldn’t, unless it’s an elephant or cape buffalo.

You see which way this goes, don’t you? Little gives way to big. Big overpowers little. It’s a rule of nature. No way can the mouse clamp its ferocious jaws around the neck of the antelope. Read more… »

The Associated Press, as reported in the Los Angeles Times, keep to their warmist line. Now they’re keen to highlight a steep increase in carbon dioxide emissions, without letting on that it hasn’t affected the temperature.

The global output of heat-trapping carbon dioxide jumped last year by the biggest amount on record, the U.S. Department of Energy calculated, a sign of how feeble the world’s efforts are at slowing man-made global warming.

The new figures for 2010 mean that levels of greenhouse gases are higher than the worst-case scenario outlined by climate experts just four years ago.

In 2008, the annual increase was half of the year before. Now there’s a crisis?

It is a “monster” increase that is unheard of, said Gregg Marland, a professor of geology at Appalachian State University, who has helped calculate Department of Energy figures in the past.

Which just means it hasn’t happened before that we know of.

Climate Realists carried a letter from John O’Sullivan on 2 November, claiming ill treatment at the hands of Suite101.com, in terminating their publishing arrangement with him. I note that two of O’Sullivan’s articles are still available at Suite101 but this is his letter:

Friends,

I write to announce my employment with my publishers, Suite101 was terminated today without prior notice or explanation and all my articles published over a two-year period with them are now removed from the Internet. I believe this is in retaliation for my latest article ‘New Satellite Data Contradicts Carbon Dioxide Climate Theory’ revealing the shocking fact that the Japanese ‘IBUKI’ satellite measuring surface carbon dioxide emissions shows that Third World regions are emitting considerably more CO2 than western, industrial nations. Read more… »

Now where should we start?

How confusing is this?

Climate Realists announce that new satellite data from Japanese scientists show carbon dioxide is emitted mostly by the third world, with much less coming from industry in the west. For those asleep in the back, that’s the reverse of our previous understanding (so it’s a confusing result). On the map, pink is where emissions are occurring, green is where absorption is occurring.

Hmm, New Zealand apparently doesn’t exist. Panic!

Life is now officially upside down — the giant northern hemisphere economies are not emitting CO2 after all, they’re absorbing the stuff! Read more… »

Evidence that observed or predicted levels of atmospheric carbon dioxide will cause sufficiently strong widespread acidification to harm shellfish is difficult to obtain.

The School of Chemical Sciences at the University of Auckland hosted a lecture by Assoc-Prof. Mary A. Sewell, of the School of Biological Sciences, on “Ocean Acidification: Integrating chemistry and marine biology and what it means for you.“
 
Our friend Roger Dewhurst, engineering geologist and founding member of the NZ Climate Science Coalition, went along and paid close attention. Then he sent Mary Sewell the following entertaining and informative letter, which he kindly shares with us to provoke conversation.

Past is key to future; CO2 ruined nothing before; there’s no evidence of ruin to come; alarming climate predictions are inconsistent and unconvincing.

Roger Dewhurst writes:

Thanks for an interesting seminar.

Demonstrating that the appendages of a larval echinoderm tend to be stunted when the little beastie is grown in soda water is one thing. To extrapolate that to an absence of oysters, mussels and scallops on the dinner table next year is, in my view, stretching things a little too far. I was reminded of Al Gore’s polar bear on an iceberg!

When I was at Victoria University in the 1960s science was divorced from politics, and zoology, botany and geology were separate subjects. Now zoology and botany are lumped together as biology, and geology has been lumped in with geography as earth science and includes — would you believe it — a strand called ‘feminist geography’. I suppose that feminist mathematics is next in the pipeline. Sic transit gloria ["thus fades the glory of the world" – RT].

I suspect, on the basis of opinions from two universities, that no science student will get a decent degree now without paying obeisance to anthropogenic global warming and its apostles, ‘Piltdown’ Mann and his gang who, I presume, you know as ‘The Team’. This is not science as I know it but the ‘science’ of Lysenko. Read more… »

Well, now we have a peer-reviewed scientific paper that says you can.

It’s hard to know what to say about Tom Wigley’s new paper on the climatic repercussions of replacing coal with natural gas: he says gas and coal are both good, and they’re both bad, but the truly remarkable thing is that, where for years the greens have been telling us to hate coal and everyone who uses it, now it’s hard to choose between coal and gas.

It doesn’t matter whether you believe mankind is warming the planet dangerously or not, Wigley tells us that it makes hardly any difference to the warming whether you use gas or coal. So why switch to gas? There’s no advantage in it. Read more… »

Human emissions of CO2 1990 to 2010.
From PBL Netherlands Environmental Assessment Agency.

Two days ago we heard about the long-term trend in atmospheric carbon dioxide emissions, copied above.

This graph functions as a fine graph of productive output, and doesn’t it reveal the new world order? The countries with the highest emissions are (broadly speaking) doing the most work, making the most money and having the most influence.

It was ever so. If our leaders wake up to that simple fact they might be able to make sensible plans to maximise our work. Perhaps improve on the half-baked notion of a magic “knowledge economy” — as though knowledge alone would succeed without the application of intelligent planning, consistent effort and good service.

The sky, location of most of the climate.

Yesterday I saw the headline: Climate change reducing ocean’s carbon dioxide uptake. If they mean the temperature’s been rising, I thought, these guys need a lesson in 1) recent, 15-year-long atmospheric temperature non-rise and 2) the gas laws, or specifically, Henry’s Law.

Henry’s Law states that the solubility of a gas in a liquid at a particular temperature is proportional to the pressure of that gas above the liquid. If the temperature of the liquid rises, it can’t hold so much gas, so some will leave (“outgas”). It hardly requires a paper based on 28 years of observations to confirm this. Read more… »

The methane molecule – one atom of carbon with four hydrogen atoms, the simplest alkane and the principal component of natural gas. Burning it in the presence of oxygen produces nothing but carbon dioxide and water. It’s found on other planets, as though it belonged there. We burn far more than we create and create far too little to bother with. The largest natural source apart from deep underground is wetlands.

In July last year, and after more than a year’s absence, NIWA got around to publishing another issue of their “flagship” publication, Water & Atmosphere. It’s an attractive magazine, but it contains some curious information which deserves comment.

First, we notice a helpful comment by NIWA Chief Executive, John Morgan:

NIWA has a responsibility as a Crown Research Institute to share the results of publicly-funded science.

Hmm. Morgan should compare that statement with the conclusion of the methane article in the same issue:

if any real solution [to agricultural emissions] is on the horizon it’s likely to be a closely kept secret.

The article has some gems:

methane levels have grown by 150 per cent since organised animal farming began in the early 1700s.

They tell us methane’s a problem

Was farming disorganised until the 18th century? That’s not what the history books say. Read more… »

A suit in handcuffs. Only the educated, trusted men can engage in theft on this grand scale — £156 million! This story concerns GST fraud (called VAT in Europe) but there are easier scams occurring in the carbon trading field, based on the simple fact that the only thing being sold is thin air. Actually, it’s worse than that: they’re selling CO₂. Unmeasurable, invisible and useless to both buyer and seller. At least air is of some use. What a confidence trick!

Sends shivers down the spine, this does. For, not only does “regular” carbon trading take food from the mouths of mothers and babies, but fraudulent activities, increasing costs and therefore prices, take even more. How long before it turns up in New Zealand, if National really does launch its ill-advised scheme on July 1? The most important part of the story waits until the last two paragraphs, though I’ve flagged it in the heading. Further comments below.

On 8 March, 2010, David Archibald wrote a guest post on WUWT entitled “The Logarithmic Effect of Carbon Dioxide”. This was brought to my attention recently as an article worthy of attention, so here it is.

The greenhouse gases keep the Earth 30° C warmer than it would otherwise be without them in the atmosphere, so instead of the average surface temperature being -15° C, it is 15° C. Carbon dioxide contributes 10% of the effect so that is 3° C. The pre-industrial level of carbon dioxide in the atmosphere was 280 ppm. So roughly, if the heating effect was a linear relationship, each 100 ppm contributes 1° C. With the atmospheric concentration rising by 2 ppm annually, it would go up by 100 ppm every 50 years and we would all fry as per the IPCC predictions.

But the relationship isn’t linear, it is logarithmic. In 2006, Willis Eschenbach posted this graph on Climate Audit showing the logarithmic heating effect of carbon dioxide relative to atmospheric concentration:

The logarithmic relationship between atmospheric CO₂ concentration and temperature forcing. In other words, Willis Eschenbach shows that later increments of carbon dioxide added to the atmosphere have lesser effects on atmospheric temperature.

And this graphic of his shows carbon dioxide’s contribution to the whole greenhouse effect:

Come tell us your opinion while it’s fresh!

We want to know if you think that carbon dioxide dominates the climate. Note that does not mean simply “affects” the climate: do you think it dominates?

Because it’s quite clear to us that for carbon dioxide to be declared quite the villain it is made out to be, it must dominate climate in a very dominating way! It must be, in fact, the most dominating thing in a dominantly long time, climatically speaking. It must dominate the climate as a mushroom shades a blade of grass in that completely over-shadowing, dominating kind of mushroomy way.

What do you think? Vote here.

Tell everyone.

Thank you.

The science is never settled. Only we are settled. What we knew for certain last week, last year or even for half a life might need reforming today.

Over the last ten years or so, as the heat faded from the warming dimension of climate change, so alarm was raised about the dire effects of ocean “acidification”. The mainstream media began to describe the appalling effects on sea life, especially creatures with exoskeletons, of the increasingly “acid” waters being created by higher and higher levels of carbon dioxide (CO₂) in the atmosphere.

Coral reefs were doomed, many even now were “suffering” and all were in peril of destruction if we continued “spewing” huge quantities of CO₂ into the air. Crabs, crayfish, shellfish of all kinds, plankton and krill were all at risk, and their decline spelt doom for the higher creatures in the sea, even unto man himself, who eats them.

Now, published in the December 1 issue of Geology, comes a remarkable—and remarkably courageous—study from the Woods Hole Oceanographic Institution that shows many denizens of the oceans benefit hugely from that increased CO₂. Did you predict that?

The study makes it clear that many forms of oceanic life are disadvantaged to some degree by increased acidification, but this message is very different from the hitherto confident, ceaseless prognostications of universal doom proceeding from the pens of the alarmists. The scientists are calling for more detailed studies to be done, because there is so much to learn.

Anthony Watts, over at WUWT (hat-tip to Anthony), puts it succinctly:

And some thought ocean acidification would destroy everything.

Here’s how the media release from WHOI begins:

In a striking finding that raises new questions about carbon dioxide’s impact on marine life, Woods Hole Oceanographic Institution (WHOI) scientists report that some shell-building creatures—such as crabs, shrimp and lobsters—unexpectedly build more shell when exposed to ocean acidification caused by elevated levels of atmospheric carbon dioxide (CO₂).

Sorry, but I guess the paper itself is behind a pay-wall; there’s no link I can find at WHOI.

Gareth Hughes, an obviously earnest young man, writing in the NZ Herald recently, advises us breathlessly to take all manner of feel-good actions to stave off global warming and prevent any further drain on the national grid. As though the national grid was not supposed to supply energy for our use. That we pay for.

He seems to take the view that the Earth is a fragile, sensitive object that, without the most rigorous balancing of resources to ensure what is called “sustainability” (but which is never defined), might never recover from the ravages of this human life upon it. Never mind that animals, birds and fish rage and stamp, consume and defecate their mindless ways above, across and under it and in the oceans in their millions willy-nilly. What they do is natural but everything we do is unnatural, artificial—even inhuman, perhaps. Certainly endlessly disagreeable. Read more… »

Last Sunday the NZ Herald reported on a Kiwi woman, one Emily Hall, now a Greenpeace activist in the UK, who was in a boarding party that recently attacked what used to be called a collier—a vessel used for transporting coal.

The Herald’s story contained no censure against Greenpeace’s overt lawlessness. It was a sympathetic treatment of Hall’s experiences with Greenpeace and her and its tactics of rebellion against the Establishment in the name of the environment.

But the story incorrectly described carbon dioxide as “poisonous”.

There was nothing wrong with describing the ship’s load as “dirty” coal, since either handling the stuff or burning it inefficiently results in a mess, although modern methods of burning powdered coal, combined with smokestack “scrubbing” of most of the airborne pollutants, is thermally efficient and allows us truly to describe coal as “clean”.

But labelling “carbon emissions” as “poisonous” is just plain wrong. Carbon emissions is a euphemism for carbon dioxide and there is nothing remotely poisonous about that. Neither is it “dirty”, regardless of Greenpeace’s clumsy propaganda attempts to link it with the visible pollutants that come from coal.

Describing this clean, invisible plant food as poisonous simply attempts to justify Greenpeace’s hostility towards carbon dioxide, and thus legitimise an attack on a vessel and its crew going about their lawful business.

The Herald ought to stand aside from the campaign to wrongly vilify carbon dioxide for the activists’ political purposes.

Environmentalists have educated society first to notice, then to condemn and finally to clean up pollution of air, water and land. But now activists focus on carbon dioxide because it warms the planet. We have been induced to fear what we actually prefer.

Improvements have been achieved over many decades, and it is wonderful that, for example, the United States pollutes a lot less than it used to, has a greater area in forests now than at the end of the 19th century and enjoys cleaner rivers, like many of the developed nations, including New Zealand.

New Zealand’s Emissions Trading Scheme (ETS)—will it reduce global warming?

We breathe carbon dioxide and without it we would die. Growers routinely add it to greenhouses (four times the normal level) to make the plants grow better. Forests are growing measurably faster as the level of atmospheric CO2 climbs.

But human emissions of CO2 are allegedly warming the planet. Inducing a sense of guilt for driving a car or turning the lights on hasn’t reduced emissions. An alternative way to force emissions down is to create emission licences (or carbon credits) and then buy and sell them to each other. Entrepreneurs love it. New Zealand is setting up such a scheme right now. Read more… »
