Venus has a two hundred eighty thousand (280 000) times more CO2 in its atmosphere.
Atmosphere is very thin to play a role of a warming blanket. Atmosphere is not able to warm Earth’s surface. Unfortunatelly, when Earth’s surface temperature (288K) is compared with the surface temperature of the airless Moon (220K), some climatologists still claim it warms surface by +68°C! Opponent: Christos, Christos, Christos, explain this fact: “Venus is much hotter than Mercury, despite being further from the Sun. Venus has a surface temperature hot enough to melt lead. This high temperature is due to a thick greenhouse atmosphere that traps heat, whereas Mercury has no atmosphere to hold onto solar energy.” I look forward to your tortured response. - Answer: Thank you for your response. When comparing Venus' atmosphere vs Earth's "This high temperature is due to a thick greenhouse atmosphere that traps heat, whereas Mercury has no atmosphere to hold onto solar energy." Venus has a two hundred eighty thousand (280 000) times more CO2 in its atmosphere. It is 280 000 to 1. When co

Water vapour makes a measurable difference. But the difference is local and limited.
Yes, of course water vapour makes a measurable difference. But it is localized where and when a higher air humidity occurs. The difference is local and limited. It has nothing to do with the alleged average global +33C atmospheric greenhouse effect. Because earth is warmer than moon not from the existence of atmosphere (the blanket effect), but because earth has the planetary surface (N*cp) product 155,42 times higher than moon's.. Now let's compare Tmean.earth /Tmean.moon = 288K /220K = 1,309 and (155,42 )^1/16 = 1,3707 ////////////////////////////// Moon with Earthen Albedo a = 0,3 would have Tmean.moon = 210K 288K /210K = 1,3714 /////////////////// - https://www.cristos-vournas.com

The atmosphere is transparent to EM radiation.
The atmosphere is transparent to EM radiation. Look in the skies at night – we see distant stars and galaxies – and we see them through the atmosphere, because atmosphere is very thin and very transparent. In the day we do not see stars, the skies are of various colors. That creates an illusion, that there is something up there covering Earth as a protective blanket – which is an illusion. – Opponent: Christos Vournas wrote: "The atmosphere is transparent to EM radiation. Look in the skies at night – we see distant stars and galaxies – and we see them through the atmosphere, because atmosphere is very thin and very transparent." Think! Is the atmosphere transparent to UV radiation? No, because of ozone. Without that absorption life would likely never have developed on Earth’s surface. Some IR is absorbed on the down just as it is absorbed on the way up. And so on: https://pace.oceansciences.org/images/Solar_spectrum_en_v5.jpg Answer: There is not much UV radiation emitted by sun.

The Stefan-Boltzmann Constant Is In Error
Haven't you read the Gary Novak’s site yet? Link: https://nov79.com/stf.html "The Stefan-Boltzmann Constant Is In Error W/m² = 5.67 x 10-8 x K4 Based on the erroneous Stefan-Boltzmann constant (SBC), a house could be heated by covering the floor with ice. The SBC says 315 watts per square meter of radiation are given off by matter at 0°C (32°F). The emissivity for ice is 0.92. So 0.92 x 315 = 299 w/m². For a room that is 15 feet by 30 feet, the area can be rounded to 50 square meters. So 50 x 299 = 14,950 watts of radiation being emitted. That's equivalent to 8.3 space heaters at high level of 1,800 watts. That means ice on the floor of such a room would fry the place in minutes, as if 8.3 space heaters were going."

For the lower than 1500 K temperatures, the Stefan-Boltzmann emission Law doesn't work.
For the lower than 1500 K temperatures, the Stefan-Boltzmann emission Law doesn't work. Links: Stefan–Boltzmann law - Wikipedia Stefan Boltzmann 001 - Stefan–Boltzmann law - Wikipedia The Graph Total emitted energy, , of a black body as a function of its temperature, . The upper (black) curve depicts the Stefan–Boltzmann law, . The lower (blue) curve is total energy according to the Wien approximation, Now, when looking in the Graph, it is obvious, that the Stefan-Boltzmann emission Law - in the real world - starts from the higher temperature of about ~ 1500 K. For the lower than that temperatures, the Stefan-Boltzmann emission Law simply doesn't work. And it doesn't work, because the matter at the lower than about ~1500 K temperatures doesn't posses the required by the Stefan-Boltzmann emission Law, doesn't posses the energy needed to be able emitting as the S-B law at higher temperatures discovers happening! Thus, the commonly acccepted assertion, that S-B emission law formula is va

By adding 420 ppm, not of CO2 but of Indian ink ("encre de Chine"), to a glass of clear water.
Opponent: "The very low CO2 content is an insufficient argument (and the same is not true for water vapor, which can vary from 1% to 5% depending on the location).Low content: By adding 420 ppm, not of CO2 but of Indian ink ("encre de Chine"), to a glass of clear water, the transparency to radiation is no longer quite the same (try it!)... Analogy with CO2 and infrared?" Answer: I think we should not add 420 ppm of Indian ink to a glass of clear water. The 420 ppm of CO2 in the air are ditributed in the volume of air. Those 420 ppm are part of the air's density. In a glass of water (water is ~ 1000 times denser than air), in a glass of water we should add then 0,420 ppm of the Indian ink - to keep the analogy with transparency to radiation of the 420 ppm CO2 content in the air. Don't you agree?
