Greenhouse-Gas Theory Discredited, I

John O’Sullivan, co-author of Slaying the Sky Dragon:  Death of the Greenhouse Gas Theory, has a new article, “Greenhouse Gas Theory Discredited by ‘Coolant’ Carbon Dioxide” at suite101.com:

In his new paper, “Determination of the Total Emissivity of a Mixture of Gases Containing 5% of Water Vapor and 0.039% of Carbon Dioxide at Overlapping Absorption Bands” [Nasif Nahle] proves that in nature, [carbon dioxide] and water vapour mix together to decrease infrared radiation emissions/absorptions in the air.  This is the opposite of what conventional climatology has been saying for years.  [...]
Dr. Nahle completed his controversial study with the assistance of American physicist, Dr. Charles Anderson.  [...]
Nasif’s study looked at how well gases in our atmosphere convert energy from the sun to raise temperatures on the ground.  He went on, “In the case of carbon dioxide, its emissivity consists of its potential to emit the energy absorbed because it is not a primary source of heat.”
Nasif added, “the absorptivity coefficient of the carbon dioxide is equal to its emissivity coefficient, the gas can absorb only a limited amount of the energy received from other sources and then emit a limited amount of the energy absorbed.”  In simple terms, this means carbon dioxide cannot ‘store’ more energy than it emits.

The paper concludes:

Applying the physics laws of atmospheric heat transfer, the Carbon Dioxide behaves as a coolant of the Earth’s surface and the Earth’s atmosphere by its effect of diminishing the total absorptivity and total emissivity of the mixture of atmospheric gases.
Dr. Anderson and I found that the coolant effect of the carbon dioxide is stronger when Oxygen is included into the mixture [...] which is lower than the value [...] obtained by considering only the mixture of water vapor and carbon dioxide.

As John O’Sullivan observes, the paper by Dr. Nahle and Dr. Anderson—if verified—refutes the  doom-saying, global-warming orthodoxy.

Three Posts at the Hockey Shtick

Three excellent posts at The Hockey Shtick are well worth reading:

Physicist:  Carbon dioxide has negligible effect on climate

Semi-retired physicist Dr. Daniel M. Sweger has been a research scientist at the National Institute of Standards and Technology, where he was active in a variety of research areas, including cryogenic thermometry, solid state and nuclear physics, and molecular spectroscopy.

Dr. Sweger’s new paper, Earth’s Climate Engine (PDF), finds that if carbon dioxide [have] any effect on climate, it must be negligible.  Instead, he finds on the basis of data and theory that water vapour is the dominant influence on climate, and its influence is the opposite of that assumed by the IPCC climate computer models.

Greenpeace co-founder:  ‘Global warming is obviously a natural phenomenon’

Patrick Moore, a co-founder of Greenpeace and author of the new book, Confessions of a Greenpeace Dropout: The Making of a Sensible Environmentalist, states [...] “we do not have any scientific proof that we are the cause of global warming.”  Moore also explains how the green movement has been co-opted by the political left and has come to support policies which are harmful for the environment and humanity.

How scientific is climate science?

What is arguably the most important reason to doubt global warming can be explained in plain English.  [This article is also available here.]

By Douglas J. Keenan  WSJ.com

For years, some researchers have argued that the evidence for global warming is not nearly as strong as has been officially claimed.  The details of the arguments are often technical.  As a result, policy makers and other people outside the debate have relied on the pronouncements of a group of climate scientists.  I think that is unnecessary.  I believe that what is arguably the most important reason to doubt global warming can be explained in terms that most people can understand.
