Murdock: The chills of Global Cooling | ScrippsNews

As cap-and-trade advocates tie their knickers in knots over so-called “global warming,” Mother Nature refuses to cooperate. Earth’s temperatures continue a chill that began 11 years ago. As global cooling accelerates, global-warmists kick, scream, and push their pet theory — just like little kids who cover their ears and stomp their feet when older children tell them not to bother waiting up for Santa Claus on Christmas Eve.

Consider how the globe cooled last month:

— June in Manhattan averaged 67.5 degrees Fahrenheit, 3.7 degrees below normal — the coldest average since 1958. The National Weather Service stated July 1: “The last time that Central Park hit 85 in May…but not in June was back in 1903.”

— In Phoenix, June’s high temperatures were below 100 degrees for 15 days straight, the first such June since 1913. In California’s desert, Yucca Valley’s June average was 83.5, 8.5 degrees below normal. Downtown Los Angeles averaged 74.5 degrees, five below normal.

— Boston saw temperatures 4.7 degrees below normal. “This is the second coldest average high temp since 1872,” veteran meteorologist and Weather Channel alumnus Joseph D’Aleo reports at Icecap.com. “It has been so cool and so cloudy that trees in northern New England are starting to show colors that normally first appear in September.” Looking abroad, D’Aleo noted: “Southern Brazil had one of the coldest Junes in decades, and New Zealand has had unusual cold and snow again this year.”

Arctic temp above 80N parallel still below freezing – trend flat « Watts Up With That?

Posted by SteveB on July 2, 2009

In that article, Joe D’Aleo presented a graph from the Danish Meteorological Institute (DMI) that showed that the area above 80 degrees north had still not climbed above freezing point of fresh water. Granted sea water doesn’t freeze until around -4°C, but that not is what was most interesting. It was the flat-top appearance of the graph which when you go back though the years provided on the DMI web page, doesn’t seem to have appeared before.

This is the the DMI graph (annotated by WUWT) from yesterday’s data, July 1st, which appeared today. There is a one day update lag. The original graph is available here at DMI.

Read the rest below.

nzclimatescience.net – THE TRIUMPH OF DOUBLESPEAK

Posted by SteveB on June 28, 2009

THE TRIUMPH OF DOUBLESPEAK

Despite over 20 years of effort and four major Reports, the Intergovernmental Panel on Climate Change has not succeeded in providing any evidence that increases in greenhouse gases are having a measurable effect on the climate. Why is it, then, that so many people believe that they have done so? The answer lies in their subtle use of doublespeak, the technique of creating confusion by manipulation of language. This newsletter shows how they have confused and twisted the meanings of words in such a way as to create triumph out of failure.

CLIMATE CHANGE

The Framework Convention on Climate Change which was signed by so many nations, including our own, started the whole thing off with this definition of “Climate Change”, from  Article 1 as follows :
“a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods” 

They have suddenly changed the meaning of “climate change” which had previously not involved any particular cause, to one restricted only to its being ”attributed” to direct or indirect human changes in atmospheric composition. This means that they do not have to prove that all changes in climate have this cause.  All they need to do is to get people to use the term “climate change”, and they will suddenly discover that by saying these words they support the IPCC “attribution” whether they know it or not.

There does not need to be any actual evidence. All that is needed is for somebody. such as an IPCC climate scientist, an environmental activist, a politician, or a journalist, to “attribute” it. The “attribution” does not even need to be “direct”. “Indirect” can be as obscure as they chose it to be.

This device has been an outstanding success. Any “climate change” which is disapproved of, be it a heat wave, cold spell, flood, drought, or hurricane, is today routinely “attributed” to human influence on the atmosphere.

They confuse matters further by their additional statements. “Climate Change” is now only one of the many possible reasons for “change of climate”, a term which seems now to have replaced the original meaning of “climate change”. They are reluctant to enlarge on the possible other reasons for “change of climate” apart from “natural variability”.

“Natural Variability” evidently does not “change” it merely varies. Only “climate change” actually changes.

What is the difference between “change” and “variability”? Climate is known to vary over many different periods, from a few seconds to millions of years. How can you tell whether it is “changing” or “varying”?

They have left out altogether an important component of “change of climate”, and that is change of climate caused by humans which does not involve changes in the composition of the atmosphere.

We can put a man on the Moon….

Posted by SteveB on June 20, 2009

All this discussion about global warming and the supposed proof that Co2 is the main culprit got me thinking.  The discussion of proof, or lack therof, is centered around historical data and climate models for the most part. What was the temperature in the past? Whatever past time-frame you want to use to support your argument; And what the climate models tell us about the future climate.  Again, whatever future time frame is used to support ones argument. 

But all this discussion about what was and what will be never seems to competely include exactly how it is that Co2 causes the Earth’s temperature to increase.  We hear arguments about the so-called “greenhouse effect.”  It sounds like a very simplistic and reasonable answer.  But if it were such a simple and reasonable answer, why are there so many scientists that do not support this view?

To use an old phrase…”We can put a man on the moon, but we can’t…..” This is really the key to the entire issue.  We can talk ad homonym about past temperature records, climate models, ice melt, the loss of glaciers, the recent cooling, or past 30 year warming all we want.  But the real discussion should be – how exactly does Co2 cause the Earth to warm, if it does at all?

I did a Google search.  “How does Co2 cause global warming.”  I didn’t get much in terms of an actual answer.  Probably the clearest and simplest answer I found is below.  See the paragraph italicized for emphasis.  This is the crux of the entire debate.

One simple little statement.

How does carbon dioxide cause global warming? (Lansing State Journal, August 31, 1994) ——————————————————————

Fossil fuels such as gasoline, methane and propane contain mostly carbon. When these fuels are burned, they react with oxygen and produce carbon dioxide.

Because of our heavy use of fossil fuels, the amount of carbon dioxide in the atmosphere has been increasing since the industrial revolution.

The destruction of forests which use carbon dioxide also contributes to the increase in carbon dioxide.

Most of the light energy from the sun is emitted in wavelengths shorter than 4,000 nanometers (.000004 meters). The heat energy released from the earth, however, is released in wavelengths longer than 4,000 nanometers. Carbon dioxide doesn’t absorb the energy from the sun, but it does absorb some of the heat energy released from the earth. When a molecule of carbon dioxide absorbs heat energy, it goes into an excited unstable state. It can become stable again by releasing the energy it absorbed. Some of the released energy will go back to the earth and some will go out into space.

So in effect, carbon dioxide lets the light energy in, but doesn’t let all of the heat energy out, similar to a greenhouse.

Currently, the amount of carbon dioxide in the atmosphere is increasing at the rate of about one part per million per year. If this continues, some meteorologists expect that the average temperature of the earth will increase by about 2.5 degrees Celsius. This doesn’t sound like much, but it could be enough to cause glaciers to melt, which would cause coastal flooding.  END.

This is what it all comes down to.  Co2 absorbs some of the Sun’s energy that would otherwise be radiated back into space from Earth and holds it in the atmosphere.  Why can’t all the great minds in the world get together to figure this out?  I know there is actually is a great deal of literature out there that explains how there is no real greenhouse effect.  But the point is, why so much disagreement?  It doesn’t seem like it should be so complicated to at least figure that out. 

As I said, we can put a man on the Moon…

A Few Simple Words to Correct the Frauds on Global Warming.

A Few Simple Words to Correct the Frauds on Global Warming
 

Each person has a different concept of what is happening based on different knowledge. This is often true within science, where each scientist is only familiar with a small part of the subject. Climate science is so complex, with so many details, that most people cannot grasp it all. So this description attempts to cut through the confusion with summary statements in simple language. Read the entire article below.

A Few Simple Words to Correct the Frauds on Global Warming..

Propaganda is all the public gets, and a lot of erroneous assumptions result. “Climate change” is supposed to mean the climate is doing something it otherwise would not do. “Heat trapping gasses” is supposed to mean greenhouse gasses prevent heat from leaving the atmosphere. Why would scientists use those terms if they didn’t mean what they say? Because those terms are propaganda statements used by frauds. So here’s an attempt to cut through those frauds with simple explanations:

Greenhouse gasses do not trap much heat for many reasons. The number one reason is because they can only trap radiation, while radiation is almost nonexistent for them. The sun’s energy cannot be trapped by greenhouse gasses, because it is too high of a frequency, being in the visible range, while greenhouse gasses absorb low frequency radiation, which is invisible, called infrared radiation. (Small exceptions have no bearing on the subject and are not argued.)

Remove the Golden Egg (CO2) from EPA’s GHG Basket — MasterResource

Posted by SteveB on June 17, 2009

Remove the Golden Egg (CO2) from EPA’s GHG Basket

In its Proposed Endangerment and Cause or Contribute Findings for Greenhouse Gases Under Sections 202(a) of the Clean Air Act , the Environmental Protection Agency (EPA) places six greenhouse gases into one basket. All are treated as equal, primary culprits in the anthropogenic enhancement of the earth’s greenhouse effect, and thus the EPA proposes to find that they “endanger the public health and welfare of current and future generations.” The six are carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride.

But for many reasons, one of these gases is not like the others and should be considered separately. That gas is carbon dioxide.

American Thinker Blog: WSJ Publishes Nutty Global Warming Geoengineering Plan

WSJ Publishes Nutty Global Warming Geoengineering Plan

Marc Sheppard
Can you imagine anyone being loony enough to declare an unproven solution to an unproven problem to be “enormously risky” and certain to “lead to troubling unforeseen consequences” and “international tension,” and then proceeding to advocate for it nonetheless?   Or a highly respected international news source making the decision to publish such lunacy as a cover story?

Try this — in today’s Wall Street Journal article It’s Time to Cool the Planet, Jamais Cascio, a San Francisco “Environmental Futurist,” claims that it’s too late to avoid an “unprecedented global catastrophe” by merely cutting down on greenhouse gas emissions.   No, in addition to shutting down progress in a futile effort to reduce atmospheric CO2 levels, we must also take steps to counteract the warming we’ve already supposedly unleashed in order to “delay potentially catastrophic ‘tipping point’ events.”  Such “geoengineering” would represent a “stay of execution” while we work toward “a pardon.”  Oh brother.

Cascio divides geoengineering into two categories: carbon management and temperature management.  The former, which involves methods aimed at scrubbing CO2 from the atmosphere, he dismisses as too slow to meet the task.  That leaves us with attempting to block or reflect some of the sunlight that hits the planet. According to Cascio, “increasing the planet’s reflectivity by 2% could counter the warming effects of a doubling of CO2 emissions.”  And from where did he derive such figures, perchance the same ouija board used by Secretary of Energy Steven Chu to predict that simple reflective engineering would have the same effect on global warming as taking all the cars in the world off the world’s roads for 11 years?

The True Climate Mechanisms by Stephen Wilde | Climate Realists

Posted by SteveB on June 12, 2009

Stephen Wilde

Changing global temperatures induce air circulation changes as the air seeks to restore the sea surface/surface air temperature equilibrium and at the same time resolve ocean induced variations in the sun to sea / air to space equilibrium.

The circulation changes alter all the processes involved in the rate of energy transfer from surface to space. In so far as the air circulation fails for a time to maintain temperature stability then radiation from surface to space will also change but in due course stabilty is always restored between the four said parameters (sea surface / surface air / sun to sea / air to space).

Only huge catastrophic changes capable of altering the temperature of the whole body of the oceans can set a new global equilibrium in the short term (less than millennia). The sun can also do it gradually but it takes centuries e.g. from Roman Warm Period to Mediaeval Warm Period to Little Ice Age to now. The solar effect is heavily modulated over time by ocean cycles. A change in the composition of the air alone cannot do it.
