GREENHOUSE GASSES USEFUL IN GREENHOUSES, PERHAPS

I’ve never been sure what was what re: global warming.  I have always been suspicious of the argument that global warming must be due to greenhouse gasses since all but 8 of the world’s scientists agree.  That could be merely an expression of one of the most common fallacies, appeal to authority.  This article seems quite credible.

New study blows global warming ‘greenhouse theory out of the water’

‘All observed climatic changes have natural causes completely outside of human control’

A new scientific paper contends the entire foundation of the man-made global-warming theory – the assumption that greenhouse gases warm the atmosphere by trapping heat – is wrong. If confirmed, the study’s findings would crush the entire “climate change” movement to restrict CO2 emissions, the authors assert. Some experts contacted by WND criticized the paper, while others advised caution.

Still others suggested that the claimed discovery represents a massive leap forward in human understanding – a “new paradigm.”

The paper argues that concentrations of CO2 and other supposed “greenhouse gases” in the atmosphere have virtually no effect on the earth’s temperature. They conclude the entire greenhouse gas theory is incorrect.

Instead, the earth’s “greenhouse” effect is a function of the sun and atmospheric pressure, which results from gravity and the mass of the atmosphere, rather than the amount of greenhouse gases such as CO2 and water vapor in the atmosphere.

The same is true for other planets and moons with a hard surface, the authors contend, pointing to the temperature and atmospheric data of various celestial bodies collected by NASA.

So precise is the formula, the authors of the paper told WND, that, by using it, they were able to correctly predict the temperature of other celestial bodies not included in their original analysis.

The paper

The paper, published recently in the journal Environment Pollution and Climate Change, was written by Ned Nikolov, a Ph.D. in physical science, and Karl Zeller, retired Ph.D. research meteorologist.

The prevailing theory on the earth’s temperature is that heat from the sun enters the atmosphere, and then greenhouse gases such as CO2, methane and water vapor trap part of that energy by preventing it from escaping back into space. That theory, which underpins the anthropogenic global-warming hypothesis and the climate models used by the United Nations, was first proposed and developed in the 19th century. However, the experiments on which it was based involved glass boxes that retain heat by preventing the mixing of air inside the box with air outside the box.

The experiment is not analogous to what occurs in the real atmosphere, which does not have walls or a lid, according to Nikolov and Zeller.

The new paper, headlined “New Insights on the Physical Nature of the Atmospheric Greenhouse Effect Deduced from an Empirical Planetary Temperature Model,” argues that greenhouse theory is incorrect.

“This was not a pre-conceived conclusion, but a result from an objective analysis of vetted NASA observations,” Nikolov told WND.

The real mechanisms that control the temperature of the planet, they say, are the sun’s energy and the air pressure of the atmosphere. The same applies to other celestial bodies, according to the scientists behind the paper.

To understand the phenomena, the authors used three planets – Venus, Earth and Mars – as well as three natural satellites: the Moon of Earth, Titan of Saturn and Triton of Neptune. They chose the celestial bodies based on three criteria: having a solid surface, representation of a broad range of environments, and the existence of reliable data on temperature, atmospheric composition and air pressure.

“Our analysis revealed a poor relationship between global mean annual temperature] and the amount of greenhouse gases in planetary atmospheres across a broad range of environments in the Solar System,” the paper explains.

“This is a surprising result from the standpoint of the current Greenhouse theory, which assumes that an atmosphere warms the surface of a planet (or moon) via trapping of radiant heat by certain gases controlling the atmospheric infrared optical depth,” the study continues.

The paper outlines four possible explanations for those observations, and concludes that the most plausible was that air pressure is responsible for the greenhouse effect on a celestial body.

In essence, what is commonly known as the atmospheric “greenhouse” effect is in fact a form of compression heating caused by total air pressure”, the authors told WND in a series of e-mails and phone interviews, comparing the mechanics of it to “the compression in a diesel engine that ignites the fuel.”

And that effect is completely independent of the so-called “greenhouse gases” and the chemical composition of the atmosphere, they added.

“Hence, there are no greenhouse gases in reality – as in, gases that can cause warming,” Nikolov said when asked to explain the paper in layman’s terms.

“Humans cannot in principle affect the global climate through industrial emissions of CO2, methane and other similar gases or via changes in land use,” he added. “All observed climatic changes have natural causes that are completely outside of human control.”

For the first time, Nikolov said, there is now empirical evidence from NASA data that the greenhouse effect of the atmosphere is not caused by the trapping of heat, but by the force of atmospheric pressure. The pressure is the weight of the atmosphere, he added. And the combination of gravity and the mass of the atmosphere explains why the Earth, for example, is warmer than the moon.

“The moon receives about the same amount of heat from the sun as Earth, yet it is 90 degrees [Celsius] colder than the Earth, because it has no atmosphere,” Nikolov explained.
