University of Ireland Lab Experiment Further Discredits Greenhouse Gas Theory

Laboratory experiment devised by scientists in Ireland appears to demonstrate that the greenhouse gas theory of man-made global warming is wrong.

The theory states that adding more carbon dioxide into the atmosphere causes higher temperatures. But skeptics point to global thermometers that have been flat-lining this century – all despite ever-rising atmospheric carbon dioxide levels. This inconvenient truth, they claim, discredits the greenhouse gas theory (GHE), which is the scientific cornerstone of man-made global warming fears promoted by the United Nations and most western governments.

But now added to the debate comes a simple laboratory experiment developed by scientists in Ireland. This straight-forward test can even be performed by schoolchildren. It is causing a stir insofar as it appears to support the skeptics; it indicates (contrary to what climate scientists tell us) our gaseous atmosphere is likely the most efficient mode of cooling the planet. If correct, this is the exact opposite of the main claim of the GHE which tells us such atmospheric gases keep us “warmer than we would otherwise be.”

The experiment was devised by Colm O’Sullivan of the National University of Ireland and titled ‘A simple experiment to study cooling by convection and radiation’. It shows that cooling in a vacuum is slowest and convective cooling is significantly higher than is normally stated. We all know our planet is set in the vacuum of space – that being an almost perfect vacuum such that it would be hindering earth’s cooling, not helping it, according to this real-life (not theoretical) test.  The experiment is performed using a ceramic resistor (typically 10 Ω) through which a steady electric current can be passed. The temperature of the resistor is monitored by a K-type thermocouple (0 – 250 °C) in thermal contact with the surface of the resistor and interfaced to a data acquisition system.

The experiment then requires:

The resistor with the attached thermocouple [to be] placed in a bell-jar (figure 1) which may be evacuated when required. Cooling of the resistor when suspended in vacuum is predominantly by radiation (possibly with a small contribution from thermal conduction through the electric wires). Using the rheostat to control the current flowing in the resistor enables the temperature of the resistor to be raised to any selected value up to the maximum range of the thermocouple. Having switched off the current once steady state conditions have been reached, cooling curves are recorded by the data acquisition system for four different cooling environments.

The cooling curves of the four different environments – from empty vacuum to air filled – seems to lend credence to the claims of scientists at Principia Scientific International (PSI) who have, since 2010, claimed the GHE is bogus.

So how precisely does O’Sullivan’s work impact the dispute? Well, several years back three PSI researchers (Dr Martin Hertzberg, Hans Schreuder & Alan Siddons) published their controversial paper ‘A Greenhouse Effect on the Moon?’ (2010). In it they drew comparisons with temperatures on the moon versus those on earth, as well as other bodies in our solar system. They claimed that not just on earth, but every planetary body orbiting our star is “warmer that it is supposed to be” if you apply the GHE rationale. These skeptics (‘climate realists’) say gases cool – not warm – any body in which they are in direct contact. Likewise, O’Sullivan’s lab test shows cooling by convection is measurably greater than cooling by radiation.

In their 2010 ‘Moon Paper’ the PSI trio found that:

The Earth is not “unusually” warm. It is the application of the predictive GHE equation that is faulty. The ability of common substances to store heat makes a mockery of blackbody estimates. The belief that radiating trace gases explain why earth’s surface temperature deviates from a simple mathematical formula is based on deeply erroneous assumptions about theoretical vs. real bodies. These faulty assumptions are discussed in detail elsewhere, where they are shown to lead to the ‘cold earth fallacy.’

The Department of Physics, National University of Ireland thus offers independent analysts a standardized laboratory experiment using thermal physics to look at how convection and radiation on a cooling body seem to apply in the man-made global warming debate.

If this empirical evidence can be believed then gases in earth’s atmosphere are reducing the earth’s temperature more than the radiative loss of energy to the vacuum of space. If true, then one of the most cited claims of mainstream science, that our planet is “33 degrees warmer” due to carbon dioxide and the greenhouse gas effect, is wrong.

Without doubt the Irish lab test proves cooling by convection is measurably greater than cooling by radiation. And when facts prove your theory wrong, time to change the theory.
