53 Bogus Authority Statements that Earth’s Atmosphere ‘Like a Greenhouse’

Despite compelling experimental, real-world evidence to the contrary we expose over fifty junk science statements by leading authorities still claiming our atmosphere works like a greenhouse.

Among the junk science is this lecture delivered by Professor David Archer of the University of Chicago. In his video Archer explicitly depicts the atmosphere as interchangeable with a pane of glass. Note in the photo that Archer’s chalkboard diagram shows the mythical two-way heating process (upward and downward) of “back radiation” – an entirely unphysical concept unheard of in any branch of science except climatology.

Junk Greenhouse Effect as Taught by Professor David Archer Univ of Chicago http://forecast.uchicago.edu/lectures.html

The shocking reality is that students and parents are paying tens of thousands in students loans for this post-normal variant of science. Despite leading climatologists and other specialist scientists repeatedly proving that “gas does not equal glass” these authorities appear to have abandoned the best scientific evidence to promote a political agenda. Their propaganda may win research grants but no votes from honest scientists.

Principia Scientific International is one science association determined to expose these biased institutions peddling the lie that Earth’s atmosphere actually works like the glass of a greenhouse. Such bogus statements may mislead a gullible section of the public – but fellow scientists and the more informed in society know better.

Professor Archer is in some illustrious company. Below is a list of the worst offenders as we name and shame them for  misguidedly promoting the myth that carbon dioxide is “bad for the planet.” (H/T: Alan Siddons)


The greenhouse effect

The heating effect exerted by the atmosphere upon the earth by virtue of the fact that the atmosphere (mainly, its water vapor) absorbs and remits infrared radiation. In detail: the shorter wavelengths of insolation are transmitted rather freely through the atmosphere to be absorbed at the earth’s surface. The earth then reemits this as long-wave (infrared) terrestrial radiation, a portion of which is absorbed by the atmosphere and again emitted (see atmospheric radiation). Some of this is emitted downward back to the earth’s surface (counter-radiation).

The mean surface temperature for the entire world, 14 degrees C, is almost 40 degrees C higher than the mean temperature required for radiative equilibrium of a black body at the earth’s mean distance from the sun. It is essential, in understanding the concept of the greenhouse effect, to note that the important additional warming is due to the counterradiation from the atmosphere. The glass panes of a greenhouse function in this manner, hence the name.


2. Bigelow Laboratory for Ocean Sciences

In a greenhouse, visible light (e.g., from the Sun) easily penetrates glass or plastic walls, but heat (in the form of infrared radiation) does not. The greenhouse effect refers to the physical process by which atmospheric gases allow sunlight to pass through but absorb infrared radiation thus acting like a blanket trapping heat.


3. United States Environmental Protection Agency

Greenhouse Effect

The energy that is absorbed is converted in part to heat energy that is re-radiated back into the atmosphere. Heat energy waves are not visible, and are generally in the infrared (long-wavelength) portion of the spectrum compared to visible light. Physical laws show that atmospheric constituents – notably water vapor and carbon dioxide gas – that are transparent to visible light are not transparent to heat waves. Hence, re-radiated energy in the infrared portion of the spectrum is trapped within the atmosphere, keeping the surface temperature warm. This phenomenon is called the “greenhouse effect” because it is exactly the same principle that heats a greenhouse


4. Fort Lewis College, Colorado

This partial trapping of solar radiation is known as the greenhouse effect. The name comes from the fact that a very similar process operates in a greenhouse. Sunlight passes relatively unhindered through glass panes, but much of the infrared radiation reemitted by the plants is blocked by the glass and cannot get out. Consequently, the interior of the greenhouse heats up, and flowers, fruits, and vegetables can grow even on cold wintry days.



5. Planet Connecticut.org

Glass is transparent to sunlight, but is effectively opaque to infrared radiation. Therefore, the glass warms up when it absorbs some of the infrared radiation that is radiated by the ground, water, and biomass. The glass will then re-radiate this heat as infrared radiation, some to the outside and some back into the greenhouse. The energy radiated back into the greenhouse causes the inside of the greenhouse to heat up.


6. United Nations Framework Convention on Climate Change

Greenhouse gases make up only about 1 per cent of the atmosphere, but they act like a blanket around the earth, or like the glass roof of a greenhouse — they trap heat and keep the planet some 30 degrees C warmer than it would be otherwise. http://unfccc.int/essential_background/feeling_the_heat/items/2903.php



The “greenhouse effect” is the warming of climate that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the “greenhouse,” but blocking Earth’s heat from escaping into space. http://www.gsfc.nasa.gov/gsfc/service/gallery/fact_sheets/earthsci/green.htm


Why is this process called “The Greenhouse Effect?” Because the same process keeps glass-covered greenhouses warm. The Sun heats the ground and greenery inside the greenhouse, but the glass absorbs the re-radiated infra-red and returns some of it to the inside.



A real greenhouse is made of glass, which lets visible sunlight through from the outside. This light gets absorbed by all the materials inside, and the warmed surfaces radiate infrared light, sometimes called “heat rays”, back. But the glass, although transparent to visible light, acts as a partial barrier to the infrared light. So some of this infrared radiation, or heat, gets trapped inside.


10. Dept of Atmospheric and Oceanic Science at the University of Maryland

A real greenhouse is enclosed by glass walls and ceilings. Glass is highly transparent in the visible wavelengths of the sun, so sunlight freely passes into the greenhouse. However, glass is highly absorbing in the infrared wavelengths characteristic of emission by earth’s surface. Therefore, the infrared radiation emitted by the surface is efficiently absorbed by the glass walls and ceiling, and these surfaces, in turn, radiate energy back into the interior of the greenhouse, as well as outward to the environment. But clearly, a large portion of the infrared radiation from the surface does not pass outward from the greenhouse, and the equivalent energy is contained within the greenhouse environment. http://www.atmos.umd.edu/~owen/CHPI/IMAGES/grnhs1.html

11. How Stuff Works

Light passes through the glass into the greenhouse and heats things up inside the greenhouse. The glass is then opaque to the infrared energy these heated things are emitting, so the heat is trapped inside the greenhouse. http://home.howstuffworks.com/question238.htm

12. Enviropedia.org.uk

Greenhouse gases like water vapour, carbon dioxide, methane and nitrous oxide trap the infrared radiation released by the Earth’s surface. The atmosphere acts like the glass in a greenhouse, allowing much of the shortwave solar radiation to travel through unimpeded, but trapping a lot of the longwave heat energy trying to escape back to space. This process makes the temperature rise in the atmosphere just as it does in the greenhouse. This is the Earth’s natural greenhouse effect and keeps the Earth 33°C warmer than it would be without an atmosphere, at an average 15°C. In contrast, the moon, which has no atmosphere, has an average surface temperature of -18°C. http://www.enviropedia.org.uk/Climate_Change/Greenhouse_Effect.php

13. University of Alaska-Fairbanks, Physics Department

Greenhouse gases act as a blanket. Some of you may wonder how a green house takes solar energy and turns it into thermal energy. A good example of this is something you can observe every day in the summer in you own car. It happens when you leave you car in a sunny parking lot with the windows up. The solar energy is passing through the glass and is heating the cars interior. What’s really happening is the short wave infrared waves are going in and are turning into long wave infrared waves, which cannot escape.


14. Climate.org

Fortunately, much of this infrared radiation is absorbed in the atmosphere by the so-called greenhouse gases, making the world much warmer than it would be without them. These gases act rather like the glass in a greenhouse, which allows sunlight to enter, provides shelter from the wind and prevents most of the infrared energy from escaping, keeping the temperature warm.


15. State of Utah Office of Education

On a global scale, carbon dioxide, water vapor, and other gases present in the atmosphere are similar to the glass in a greenhouse. Ultraviolet radiation from the sun (having a short wavelength) can pass through the glass. Once inside the greenhouse, the ultraviolet radiation is absorbed by soils, plants, and other objects. Upon absorption, it becomes infrared radiation or heat energy having a shorter wavelength. Because of this, infrared radiation cannot escape through the windows. The windows act like a large blanket in which they reradiate the infrared energy back into the greenhouse. This phenomenon naturally causes the overall temperature within the greenhouse to increase. http://www.usoe.k12.ut.us/curr/science/core/earth/sciber9/Stand_6/html/1e.htm

16. G.H.P. Dharmaratna, Director General Department of Meteorology

In order to understand the greenhouse effect on earth a good place to start is in a greenhouse. A greenhouse is kept warm because energy coming in from the sun (in the form of visible sunlight) is able to pass easily through the glass of the greenhouse and heat the soil and plants inside. But energy which is emitted from the soil and plants is in the form of invisible infrared radiation; this is not able to pass as easily through the glass of the greenhouse. Some of the infrared heat energy is trapped inside; this is the main reason why a greenhouse is warmer than outside.


17. Weather-Climate.org

This warming effect is called the “greenhouse effect” because it is the same process as that which occurs in a greenhouse on a sunny day. The glass is transparent to short-wave radiation but absorbs the outgoing long-wave radiation, causing a rise in temperature inside the greenhouse.


18. Eduhistory.com

The glass used for a greenhouse acts as a selective transmission medium for different spectral frequencies, and its effect is to trap energy within the greenhouse, which heats both the plants and the ground inside it. This warms the air near the ground, and this air is prevented from rising and flowing away. This can be demonstrated by opening a small window near the roof of a greenhouse: the temperature drops considerably. Greenhouses thus work by trapping electromagnetic radiation and preventing convection.


19. Northwestern University, Evanston, Illinois

Overview: Carbon Dioxide is identified as “greenhouse gas” because of its ability to trap heat within earth’s environment. …Explain that the greenhouse effect works in a somewhat similar — but not entirely the same — way (see teacher notes and background supplement sheet for more information). The sun’s rays pass through the atmosphere and warm the surface. The earth emits some of this energy back into space (like heat from a campfire). But gases such as carbon dioxide and water vapor (in clouds) absorb much of this energy and send it back to earth. People have come to call this process the “greenhouse effect” because it reminds them of how actual greenhouses, which are made out of glass and grow plants, let the sun’s rays in while trapping much of the radiation that would otherwise escape. http://www.letus.northwestern.edu/projects/gw/pdf/C09.pdf

20. NASA

There are many greenhouse gases, but the most abundant greenhouse gases are water vapor and carbon dioxide. Shortwave radiation from the sun passes through greenhouse gases, but longwave radiation is absorbed by them. Greenhouse gases absorb longwave radiation that is emitted by the surface of the earth. Subsequently, they re-emit the energy as longwave radiation in all directions. About half of the re-emitted longwave radiation does escape into space, and contributes to the planet’s radiative equilibrium. About half of the longwave radiation emitted by the gases is directed back toward the surface of the earth. As a result, a continual exchange of longwave radiation takes place between the surface of the earth and the atmosphere above it. The longwave radiation contained in this exchange causes the warming effect known as the greenhouse effect. This phenomenon is known as the greenhouse effect because, like the glass on a greenhouse, the atmosphere traps some of the energy beneath it. http://earthobservatory.nasa.gov/Laboratory/PlanetEarthScience/GlobalWarming/GW_Movie3.html

21. National Oceanic and Atmospheric Administration (NOAA)

What is the Greenhouse Effect? The glass walls and roof of a greenhouse allow most of the sun’s light in, but do not allow most of the heat to escape. This causes the temperature inside the greenhouse to be warmer than outside. The earth’s atmosphere, and in particular carbon dioxide (CO2) and water vapor (H2O), acts like a greenhouse, trapping heat and making the earth warmer.


22. National Oceanic and Atmospheric Administration (NOAA)

The greenhouse effect occurs when the atmosphere of a planet acts much like the glass in a greenhouse. Like the greenhouse glass, the atmosphere allows visible solar energy to pass through, but it also prevents some energy from radiating back out into space. The greenhouse effect insures that the surface of a planet is much warmer than interplanetary space because the atmosphere traps heat in the same way a greenhouse traps heat. Certain gases in our atmosphere, called greenhouse gases, tend to reflect radiant energy from the Earth’s atmosphere back to the Earth’s surface, improving the atmosphere’s ability to trap heat.

The greenhouse effect occurs when the atmosphere of a planet acts much like the glass in a greenhouse. Like the greenhouse glass, the atmosphere allows visible solar energy to pass through, but it also prevents some energy from radiating back out into space. http://www.fsl.noaa.gov/outreach/education/samii/SAMII_Act6.pdf

24. Draft of IPCC Fourth Assessment Report

The name “greenhouse effect” comes from the analogy with a greenhouse made of glass which allows sunlight to enter but restricts infrared energy from leaving, thus warming the interior. […] The natural greenhouse effect is neither harmful nor mysterious. Its basic principles are well-understood and are firmly based on fundamental physics.


25. Hunan University, China

• Light from the sun includes the entire visible region and smaller portions of the adjacent UV and infrared regions.

• Sunlight penetrates the atmosphere and warms the earth’s surface.

• Longer wavelength infrared radiation is radiated from the earth’s surface.

• A considerable amount of the outgoing IR radiation is absorbed by gases in the atmosphere and reradiated back to earth.

The gases in the atmosphere that act like glass in a greenhouse are called greenhouse gases.


26. The Public Broadcasting Service (PBS)

In part, we owe our existence to a process called the greenhouse effect. Inside an artificial greenhouse filled with plants, the surrounding glass traps the sun’s energy, making it warm inside, even while outside the temperature may be much colder. This same effect happens every day on the Earth. Gases within the atmosphere act like glass, trapping the sun’s heat.


27. BBC

A greenhouse works because of the glass panels that line the roof and walls. The glass is transparent to the visible light from the sun, so sunlight can shine in and warm things inside the greenhouse. Now a body at about 35°C emits mostly infrared radiation. (On the other hand our sun, with a surface temperature of about 5500°C, emits mostly visible light.) The glass panels are opaque to infrared light. The result is that the glass lets the energy of the sun in, but won’t let it back out. This keeps the inside of a greenhouse warm. Replace the greenhouse with Earth and glass panels with atmosphere in the above example, and that is how the Earth’s greenhouse effect works.


28. University Corporation for Atmospheric Research (UCAR)

Have you ever been inside a greenhouse on a cold winter day? It might be cold outside, but inside the greenhouse lush green plants flourish in the warmth and sunshine. Greenhouses are made of glass and are designed to hold heat inside. The atmospheres of some planets are able to trap energy just like a greenhouse. Energy from the Sun can enter the atmosphere, but not all of it can easily find its way out again. What blocks the Sun’s energy from escaping a planet’s atmosphere? Unlike a greenhouse, planets do not have a layer of glass over them! Instead, molecules in the atmosphere called greenhouse gases absorb the heat.


29. University of Michigan

The “greenhouse effect” is the heating of the Earth due to the presence of greenhouse gases. It is named this way because of a similar effect produced by the glass panes of a greenhouse. Shorter-wavelength solar radiation from the sun passes through Earth’s atmosphere, then is absorbed by the surface of the Earth, causing it to warm. Part of the absorbed energy is then reradiated back to the atmosphere as long wave infared radiation. Little of this long wave radiation escapes back into space; the radiation cannot pass through the greenhouse gases in the atmosphere. The greenhouse gases selectively transmit the infared waves, trapping some and allowing some to pass through into space. The greenhouse gases absorb these waves and reemits the waves downward, causing the lower atmosphere to warm.


30. Cary Academy, North Carolina

The term “greenhouse effect” describes how the gasses in Earth’s atmosphere retain the radiant energy from the sun instead of letting it fly back out into space. The glass of the greenhouse works the same way. In short, the gasses in the atmosphere let energy in and don’t let all the energy back out. http://web1.caryacademy.org/chemistry/rushin/StudentProjects/CompoundWebSites/2000/CarbonDioxide/greenhouse_effect.htm

31. Appalachian State University, North Carolina

Selective Absorbers and Greenhouse Effect. Our atmosphere is a selective filter since it is transparent to some wavelengths and absorbs others. The greenhouse effect occurs when the energy absorbed is not all be radiated because of the filtering of the atmosphere. Some of the earth’s radiated energy is reflected back to the surface. Consequently the earth’s atmosphere has an increased temperature. This process is much like the action of glass in a greenhouse. http://www.physics.appstate.edu/courses/FirstExamReview.rtf

A. Glass represents the ‘normal’ greenhouse effect on earth and is at top of atmosphere

B. Solar shortwave radiation S largely makes it to surface

C. For energy balance, top of glass must send S back out

D. Greenhouse gases don’t have a preferred direction; they send S units in both directions – up and down

34. ThinkQuest Education Foundation

In a greenhouse, heat from the sun enters the glass. The heat in the form of infra-red light bounces and heads back up towards the glass. The glass then allows only some of this heat to escape, but reflects back another portion. This heat remains bouncing within the greenhouse. In the case of planet Earth, there is no glass, but there is an atmosphere which retains heat or releases heat.


35. Moorland School, Earth Science (UK)

Imagine that Earth has been encircled by a giant glass sphere. The heat of the sun penetrates through the glass. Some of the heat is absorbed by the Earth, and some of it is radiated back towards space. The radiated heat reaches the glass sphere and is prevented from dispersing any further. Similarly, the earth is surrounded by a blanket of gases. This blanket traps energy in the atmosphere, much the same way as glass traps heat inside a greenhouse. This results in an accumulation of energy, and the overall warming of the atmosphere. The ‘greenhouse effect’ is the popular expression for the above process. http://www.moorlandschool.co.uk/earth/greenhou.htm

36. Science Encyclopedia

The greenhouse effect is the retention by the Earth’s atmosphere in the form of heat some of the energy that arrives from the Sun as light. Certain gases, including carbon dioxide (CO2) and methane (CH4), are transparent to most of the wavelengths of light arriving from the Sun but are relatively opaque to infrared or heat radiation; thus, energy passes through the Earth’s atmosphere on arrival, is converted to heat by absorption at the surface and in the atmosphere, and is not easily re-radiated into space. The same process is used to heat a solar greenhouse, only with glass, rather than gas, as the heat-trapping material. http://science.jrank.org/pages/3148/Greenhouse-Effect.html

37. California Environmental Protection Agency

Simply put, the greenhouse effect compares the earth and the atmosphere surrounding it to a greenhouse with glass panes. Plants in a greenhouse thrive because the glass panes keep the air inside at a fairly even temperature day and night, and throughout the four seasons of the year. Just as the glass lets heat from sunlight in and reduces the heat escaping, greenhouse gases and some particles in the atmosphere keep the Earth at a relatively even temperature. http://www.arb.ca.gov/cc/factsheets/ccbackground.pdf

38. The Atmosphere, Climate & Environment (ACE) Information Programme (UK)

The greenhouse gases in the atmosphere act in a similar way to panes of glass in a greenhouse (see Figure 2 below). Radiation from the Sun (consisting mainly of visible and ultraviolet (UV) radiation) can travel through glass into the greenhouse. When this radiation is absorbed by objects in the greenhouse, it is re-radiated as infrared (IR) radiation, or heat. This heat cannot escape through the glass, so the greenhouse warms. up.


39. The University of Winnipeg

As glass in a greenhouse traps heat inside, gases in the upper atmosphere trap some of the heat escaping the Earth, creating a greenhouse effect. http://theory.uwinnipeg.ca/mod_tech/node204.html

40. The University of the Western Cape, South Africa

A greenhouse is made entirely of glass. When sunlight (shortwave radiation) strikes the glass, most of it passes through and warms up the plants, soil and air inside the greenhouse. As these objects warm up they give off heat, but these heat waves have a much longer wavelength than the incoming rays from the sun. This longwave radiation cannot easily pass through glass, it is re-radiated into the greenhouse, causing everything in it to heat up. http://www.botany.uwc.ac.za/envfacts/facts/gwarming.htm

41. Department of Environmental Affairs and Tourism, South Africa

Energy coming from the sun passes through the atmosphere and warms the Earth – but the emitted infra-red radiation coming from the Earth’s surface is partly absorbed by gases in the atmosphere and some of it is reemitted downwards, further warming the surface of the Earth and the lower levels of the atmospshere. This effect has been called the ‘greenhouse effect’ because of a similar effect caused by glass in a greenhouse: it lets sunlight into the greenhouse but in turn traps a portion of infra-red radiation (heat) inside the greenhouse. http://www.environment.gov.za/ClimateChange2005/Greenhouse_Gases_and_the_Greenhouse_Effect.htm

42. U.S. Department of the Interior, U.S. Geological Survey

The gases that encircle the Earth allow some of this heat to escape into space, but absorb some and reflect another portion back to the Earth. The process is similar in Mountain View, only, the greenhouse there is made of glass instead of gas. http://hvo.wr.usgs.gov/volcanowatch/1998/98_10_22.html

43. The Institute for Educational Technology, Italy

Just as it happens in a greenhouse where the function carbon dioxide performs in the atmosphere is played by glass-rafters, the sun’s energy arrives down at the earth, where it is partially absorbed and partially reflected. Such reflected heat, however, is reflected again, by glass as for the greenhouse, by carbon dioxide as for the atmosphere, down on earth: it is as if a part of the heat were entrapped, thus determining a growth of temperature on the ground. http://www.itd.cnr.it/ge8/rivista/inglese/num_2/galil3.htm

44. University of Cincinnati College of Engineering, Ohio

Greenhouses are much warmer inside than the air is outside because the glass is transparent to light and allows short-wavelength light to pass through and heat the contents of the greenhouse. It also reflects back the longer wavelength heat radiating within the greenhouse, thus preventing if from passing back out. In a glass greenhouse, heat builds up and gets trapped due to presence of carbon dioxide and other heat trapping gases in the upper atmosphere. CO2 is analogous to glass.


45. Miami-Dade Environmental Resources Department, Florida

The phenomenon gets its name from the similarity to a garden greenhouse. Visible light passes through the glass ceiling and walls of a greenhouse. Some of the light is absorbed, some is reflected back, and a portion of it is radiated out as heat. Glass, like carbon dioxide (CO2) and other “greenhouse gases” doesn’t allow heat to escape back out. http://www.miamidade.gov/derm/climate_change_greenhouse_effect.asp

46. University of Washington, School of Oceanography

Greenhouse effect: a blanket of water vapor and CO2 and methane CH4 traps the upward infra-red ‘longwave’ or ‘heat’ radiation. The pane-of-glass model assumes total absorption of upward infrared waves yet no absorption of visible light..both of which are not completely accurate, hence the numbers are not applicable to the real atmosphere, yet demonstrate the effect. – incoming solar radiation, I in watts/meter² – some is simply reflected back to space the rest is absorbed by ocean and land and atmosphere yet reradiated as infrared heat, both upward and downward (red arrows) – The net effect of the ‘blanket’ of atmosphere is to have more downward radiation toward the Earth’s surface than just the incident sunlight. http://www.ocean.washington.edu/courses/as222d/lecture2(6)-slides07.pdf

47. Saskatchewan Schools and School Divisions, Canada

The heat-trapping gases in the atmosphere behave like the glass of a greenhouse. They let much of the Sun’s rays in, but keep most of that heat from directly escaping. This is why they are called greenhouse gases. Without these gases, heat energy absorbed and reflected from the Earth’s surface would easily radiate back out to space, leaving the planet with an inhospitable temperature close to -19°C (2°F), instead of the present average surface temperature of 15°C (59°F).


48. U.S. House of Representatives

Select Committee on Energy Independence and Global Warming

Just like the glass of a greenhouse traps warm air inside, certain gases in the atmosphere trap heat that would otherwise escape into space. http://globalwarming.house.gov/issues/globalwarming?id=0002

49. The Austrian JI/CDM- Programme

The Earth’s atmosphere is comparable to a glass roof of a greenhouse: the short-wave solar radiation passes through nearly unhindered and warms the Earth’s surface. From the Earth’s surface, the short-wave radiation is partly absorbed and partly reflected back as long-wave thermal radiation. However, this longwave thermal radiation cannot pass the atmosphere unhindered due to the greenhouse gases but is partly reflected back again to the Earth’s surface. In absence of this natural greenhouse effect the average temperature on the Earth would not reach the present level of about plus 15 degrees Celsius, but about minus 18 degrees Celsius.


50. Torfaen County, Environment and Planning, Wales

Some of the energy from the sun is trapped inside our atmosphere as it is reflected back from the earth towards space. This natural process is called the greenhouse effect, as the atmosphere acts like the glass walls of a greenhouse, which allows the sun’s rays to enter but keeps the heat in.


51. Fort Lewis College, Physics Department, Colorado

This partial trapping of solar radiation is known as the greenhouse effect. The name comes from the fact that a very similar process operates in a greenhouse. Sunlight passes relatively unhindered through glass panes, but much of the infrared radiation reemitted by the plants is blocked by the glass and cannot get out. Consequently, the interior of the greenhouse heats up, and flowers, fruits, and vegetables can grow even on cold wintry days. http://physics.fortlewis.edu/Astronomy/astronomy%20today/CHAISSON/AT307/HTML/AT30702.HTM

52. The National Assessment Synthesis Team, US Global Change Research Program

The composition of the atmosphere is particularly important because certain gases (including water vapor, carbon dioxide, methane, halocarbons, ozone, and nitrous oxide) absorb heat radiated from the Earth’s surface. As the atmosphere warms, it in turn radiates heat back to the surface, to create what is commonly called the “greenhouse effect.”


53. University of Chicago

Professor David Archer, University of Chicago explicitly depicts the atmosphere as interchangeable with a pane of glass:

The video presentation of a lecture by Archer is highly recommend if you view here:


Archer is shown to teach the belief that panes of IR-opaque glass re-radiate heat back to the interior, thus making it hotter than it would be otherwise. Just compare the above screenshot from Archer’s lecture with Professor Lindzen’s (identical) depiction.

Fast forward the video to where Archer specifically addresses the ATMOSPHERIC greenhouse layer as a pane of glass (14:25). Quote: “We’re going to put a pane of glass to represent an atmosphere.”

Then Archer erases ‘glass’ in order to extend the layer for labeling purposes.

Later on, in response to a student’s confusion (20:40), he repeats that this layer that “hangs there magically above the ground” is indeed meant to represent the atmosphere, and scribbles “atm” beside the layer to remove any doubts.

Also note that round the 10:15 mark Archer says, “What I want to do now is to put this back in terms of watts per square meter average for the earth’s surface. So I want to divide by the area of the sphere, so that will now give us this expression in units of watts per meter squared again — and what it will do is make it simpler to draw cartoons cuz I don’t have to draw spheres anymore and shadows and all that sort of stuff.”

But look at what he proceeds to d, He repeats the same old errors of emissivity × sigma × Tg4.

But there’s not a W/m² to be found for the duration of his lecture. If he HADN’T messed up you would have seen 232 W/m² entering, 232 W/m² being emitted from the surface, and 232 W/m² being radiated back to the ground. He could have wrapped it up right then and told his students: “See folks? That’s 232 × 2 on the surface, or 464 W/m². This amounts to a 301 Kelvin surface.”

But it takes Archer to 26:50 to even NAME the base temperature he’s been discussing: 253 Kelvin, which corresponds to 232 W/m² of incoming. We wonder whether Archer even UNDERSTAND what he’s doing. It seems not. Perhaps that’s how he manages to do it.
So if you are in any doubt, despite all their long-winded denials, you can now see for yourself that the atmospheric greenhouse model is premised by these ‘authorities’ on the absurd misconception about glass greenhouses.

    The amazing thing is that these people so often confound heat and electromagnetic radiation (IR). I love the reference to “heat energy waves”??? Do they just make it up?

    Good high school physics or an AP course teaches that the glass absorbs the IR and, being in contact with the outside world, WILL lose energy to the outside. As the glass is actively cooled on the outside, most of the energy transferred or emitted by the glass will be outward with only a little inward.

    If the glass was the same temperature as the greenhouse, it would not absorb IR, but would resonate and send it back. However, being cooled on the outside, the glass is cooler and does absorb the IR. Back radiation simply is not a factor here.

    The lack of convectional heat movement drives the utility of greenhouses—something our atmosphere does quite well. The Earth is not a greenhouse.

    The “climate scientists” use a flat earth with 24/7 sunshine and neglect totally that IR is both absorbed and emitted by atmospheric gases. During sunshine the IR absorption and emission is a wash as energy is absorbed from the solar radiation going in and from the reflected and emitted radiation going out. It is during the night that these gases successfully convert heat energy to IR and emit it, with significant losses to space. As the Earth’s surface radiates IR at night, the participatory gases are quickly saturated and there is an efficient flow of radiation to space—which is why on clear winter nights in Iowa temperatures can dive from 0 to -31 deg F overnight.

    If these magical little diodes floating in our atmosphere called CO2 and water vapor allow light and heat in but block it going out, then when the planet first cooled down enough 8 billion years ago for the formation of jungles, the temperature must have been about 170 degrees F due to the massive amounts of CO2 given off and the water vapor evaporation!!! If the planet not only survived that time period but thrived with bringing forth life then shouldn’t we be glad to be warming up??? The truth is “science” is another of the Ashkenazi false religions designed to turn people from GOD. GOD created everything we see, smell, touch and feel. The earth warmed and cooled by GOD’s design for billions of years and will continue to do so for billions more. GOD put forth the “science” that makes the world work and built in evolution so all plants, insects and animals (including humans) can adapt. The most perfect thing GOD created was imperfection! Anything can appear beautiful because of being unique!
