Lets lose the back radiation terminology, we all agree on that.' 'Back radiation is a phrase, one that I don't use myself, and it is not a word that is used in technical radiative transfer studies. Judith Curry to abandon this unscientific term. Judith Curry Only recently did Professor Claes Johnson persuade long-time greenhouse gas effect believer Dr. ĭoomsaying Climatologist Abandons 'Back Radiation' Memeĭr. Professor Nasif Nahle, a recent addition to the Slayers team, has proven that application of standard gas equations reveal that, if it were real, any 'trapping' effect of the IPCC's 'back radiation' could last not a moment longer than a miniscule five milliseconds - that's quicker than the blink of an eye to all you non-scientists. The cornerstone of the IPCC claims since 1988 is that 'trapped' CO2 adds heat because it is a direct consequence of another dubious and unscientific mechanism they call 'back radiation.' In no law of science will you have read of the term 'back radiation.' It is a speculative and unphysical concept and is the biggest lie woven into the falsity of what is widely known as the greenhouse gas effect. It is only if we buy into the IPCC's 'well mixed gas' fallacy that climate extremists can then proceed to dupe us further with their next claim that this so-called 'well mixed' CO2 then acts as a 'blanket' to 'trap' the heat our planet receives from the sun. Nitrogen is 78% of the atmosphere and totally non-toxic, but if you continue to increase Nitrogen and reduce Oxygen the mixture becomes 'unbreathable.' Not 'high' in a toxic sense, only that CO2 would displace enough Oxygen that you could not have proper respiration. Without these properties CO2 would fill every low area to dangerously high levels. This 'thermal' mixing is aided by wind flow patterns, but the ratios of gases in the atmosphere are never static or uniform anywhere on Earth. Heavy CO2 warms faster and rises, as in a hot air balloon. Combining these properties allows for thermal mixing. The same principle is applied to heat transfer, the Specific Heat (SH) of air is 1.0 and the SH of CO2 is 0.8 (heats and cools faster). ĬO2: The Heavy Gas that Heats then Cools Faster!

Giving standard air a value of 1.0 then the measured SG of CO2 is 1.5 (considerably heavier). Rather than refer to unit volumes and masses, scientists use the concept of Specific Gravity (SG). This is because scientists refer to ratios based on common standards. Or, we can look at it another way to make these technical Physics relationships easy. And that is precisely what CO2 is - this miniscule trace gas (just a very tiny 0.04% of atmosphere) is heavy and is soon down and out as shown by a simple school lab0 experiment. Indeed, even high school children are taught the basic fact that gravity causes objects heavier than air to fall to the ground. Ball and his colleagues appear to be winning converts with their hard-nosed re-examination of the standard myths of climate science and this latest issue is probably one of the easiest for non-scientists to comprehend. School Children Prove Carbon Dioxide is Heavier than Airĭr. A rising group of skeptic scientists have put the 'well-mixed gas' hypothesis under the microscope and shown it contradicts not only satellite data by also measurements obtained in standard laboratory experiments.Ĭanadian climate scientist, Dr Tim Ball is a veteran critic of the 'junk science ' of the International Panel on Climate Change (IPCC) and no stranger to controversy.īall is prominent among the 'Slayers' group of skeptics and has been forthright in denouncing the IPCC claims 'I think a major false assumption is that CO2 is evenly distributed regardless of its function.' One of the least challenged claims of global warming science is that carbon dioxide in the atmosphere is a 'well-mixed gas.' A new scientific analysis not only debunks this assertion but also shows that standard climatology calculations, applicable only to temperature changes of the minor gas, carbon dioxide were fraudulently applied to the entire atmosphere to inflate alleged global temperature rises.Īcceptance of the 'well-mixed gas' concept is a key requirement for those who choose to believe in the so-called greenhouse gas effect.
