No one ever explain that CO2 reacts mostly to the 15nanometers, and according to Wiens Law that frequency correspond to a temperature of - 70 degree.

I'm trying to figure out how the Earth radiates IR in any significant way with an atmosphere sitting on it. I can see IR emitted from top of the atmosphere, but not at lowere levels.

Glass greenhouses work mostly by suppressing convection.
@grindupBaker Жыл бұрын
Yes but the thermal resistance of the enclosure including the glass is precisely analogous to the so-called "greenhouse effect" in Earth's troposphere quite aside from its reduction of the heat being carried away from the outer surface by conduction. The glass exterior (assuming cold outside) radiates less than the glass interior, and that is EXACTLY the same as the "greenhouse effect" in Earth's troposphere which is colder at top portion (its amorphous outside) than at bottom portion (its amorphous inside) so troposphere radiates less out the top than out the bottom. But of course you know all that because you're you and not Mister Know It All. Of course, like you typed the other 2 greenhouse warming features are both caused by gravity for planet Earth, gravity prevents air wafting into space and taking its heat away, except infinitesimally, and prevents much by way of molecules forming a cloud to conduct heat from Earth, so that's the same 2 duties performed by a sealed greenhouse enclosure, air can't waft through and conduction to the outside is reduced. ---------- I've come across an appalling misinformation fake description of "greenhouse effect" by an ignoramus in another video. It's had 126, 000 views.

@grindupBaker I disagree. There's no long wave radiation source in either example to interact with CO2. Earth's Greenhouse Effect is about the full atmosphere being warmed by both direct sunlight, and energy store by the Earth's surface and releasing that energy via conduction n convection. More n more are becoming aware that C02 does little to the climate.

The "Greenhouse Effect" can be explained simply to just about anybody by losing the gas fixation, like this: - Earth's troposphere gets cooler with altitude (average 78 degrees colder at top than surface) because most sunshine reaches the surface. - Colder things radiate less than warmer things. The top 0.01 mm of any water surface and the top far less than 0.01 mm of land and objects radiate upwards, but there's also some water, ice, dust, salt, ash and other solids in the troposphere and they absorb some radiation emitted up from the very same stuff below at the surface. These water, ice, dust, salt, ash and other solids in the troposphere also radiate upwards (of course) just like the exact same things did below them, but they emit LESS upwards because they're colder because they're higher than the surface. So now less radiation gets to space and that's the "Greenhouse Effect" in Earth's troposphere (for example, it makes cloudy winter nights cool slower than clear winter nights). There's also some gases that can do that like H2O, CO2, CH4, O3, N2O, CFCs and they're called "infrared-active" or "greenhouse" (not nitrogen, oxygen or argon though). The more solids or liquids or infrared-active gases there are in the troposphere then provided they can mix well to the top the more it'll reduce Earth's cooling to space and try to make Earth warmer. -------- However, the water, ice, dust, salt, ash and other solids in the troposphere also reflect some sunshine and it's a bigger effect than their "Greenhouse Effect" so overall the more solids or liquids there are in the troposphere the cooler Earth gets. The infrared-active gases like H2O, CO2, CH4, O3, N2O, CFCs don't reflect any sunshine so overall the more "greenhouse gases (GHGs)" there are in the troposphere the warmer Earth gets.

The good news about global warming is that it’s not being caused by increasing solar output or any other natural uncontrollable cause, and also that mankind generally understands that it’s the ‘amplified greenhouse effect’ which is the source of increasing global temperatures. With this in mind, it behooves us to rapidly advance and apply our scientific knowledge to the point that burning fossil fuels to produce electricity will become as antiquated as the burning of whale oil for light. Quote: “Anxiety must go. It must be replaced by faith and solemn confidence in the outworking of the divine plan.” Note: As sunlight (photons) is warming the surface of the world, surface heat energy is also radiating away from our planet in the form of ‘infrared radiation’ which passes freely thru the atmospheric gases of nitrogen and oxygen which do not absorb heat. Indeed, if it weren’t for greenhouse gases such as carbon dioxide that ‘do interact’ strongly with infrared energy and ‘impede the escape’ of Earth’s radiant heat, then the planet would be perpetually frozen solid. Thankfully, even though greenhouse gases comprise only 4/10ths of one percent of the atmosphere, they are so powerful that they maintain a ‘blanketing effect’ by constantly ‘absorbing and releasing’ infrared heat energy over and over, again and again. In doing so, they gyrate wildly, thus causing them to vigorously collide with other atmospheric molecules which, in turn, collide with other air molecules, imparting the kinetic energy of motion throughout the atmosphere - and this vibratory state registers as temperature. For the big picture, search: Marcott reconstruction chart For more, search: ‘CO2 infrared radiation quantum level’ ‘Amplified greenhouse effect’ ‘Doable solutions global warming’

But u said without greehouse effect life wouldnt be possible? How dose that happen? What amount or quantity of larger wavelength rays needs to be trapped in and how does they make life possible as from this video i have understood that green house effect helps in cold climate to grow plants etc but how dose the natural greenhouse effects the climate on the plant as a whole as our earth have warmer regions also apart from colder ones.

This is how my Falls Church, VA high school George C. Marshall of the late 1970s taught of earth's greenhouse effect. Earth's greenhouse effect is the model of a system always in saturation from the strong greenhouse gas water vapor that adds 10°F (5.55°C) to the earth's average temperature and takes place within 20 meters of the surface, typically the earth. After 20 meters from the radiating surface all the greenhouse radiant energy has been completely absorbed by greenhouse gases. Its further heat transfer is by convection i.e. gas molecules bumping into each other. At 1% average tropospheric water vapor over 99% of earth's greenhouse effect is from water vapor. This is a short and definitive description of the greenhouse effect. It is impossible to make a system in saturation such as earth's greenhouse effect have further effect by increasing its active elements. Global warming cannot be due to greenhouse gases because the system they are active in is already in saturation from the strong greenhouse gas water vapor. If earth's greenhouse effect were not in saturation then there would be huge changes in the greenhouse effect temperature retention all over the world based on how much humidity was in the air. This would be extremely exaggerated if it were true, which it is not, that some organizations cite as 33°C of average increased temperature for the greenhouse effect, where the scientific recognized average is 5.55°C. At 1% tropospheric average water vapor and 0.04% CO2: (1.00% water vapor) / (0.04% carbon dioxide) = 25 times more concentration of water vapor than than carbon dioxide. Water vapor CO2e=18 X 25 ---> 450 times more temperature forcing for water vapor than carbon dioxide. Even if earth's greenhouse effect were not in saturation CO2 would have no significant effect on it. The United Nation's IPCC science report in its back pages acknowledges that it is NOT in-fact discussing greenhouse gases in a manor constructive to the discussion of global warming by a legal statement of data transparency that it took its greenhouse gas samples at 20,000 meters altitude and only that one altitude! There is no greenhouse radiant energy more than 20 meters from the radiating surface, typically the earth. That IPCC data transparency statement of 20,000 meter altitude gas sampling is acknowledging it is not dealing with active greenhouse gases or earth greenhouse effect in a manor constructive to the discussion of global warming. This is the same marketing practice that takes place when a beverage is labeled "All Natural Fruit Flavors" and then in the ingredients it tells the truth "contains no actual fruit juices" Global warming has been paused at about 1°C since the early 1990s. Global warming was reported at 1.1°C in 1991 and 1.06°C in 2022. The physical mechanics of the greenhouse effect is that a certain band width of far inferred radiation from surface interacts loosely with the lumpy electrostatic fields of greenhouse gas molecules typified by gas molecules of largely differing sized atoms such as H2O water vapor and CH4 methane. CO2 carbon dioxide is almost inert as a greenhouse gas. The diatomic gas molecules O2 and N2 have no interaction with greenhouse radiant energy. Once the greenhouse radiant energy has been absorbed by greenhouse gases they do not reradiate the energy as their main heat transfer. Heat transfer is by convection i.e. gas molecules bumping into each other.

I would add that the outbound long wave radiation, that is required to interact with CO2, IS VIRTUALLY NON-EXISTENT. therefore there is no OLR to interact with CO2

totally missing conduction of heat from surface/plants ect to air and convection that is blocked by roof of greenhouse - Think of car in parking lot hot summer day with windows up - roll them down - hot air flows out and up. hot air rises less dense exhaust via radiation to space - the more CO2 in upper atmosphere the faster it cools. Ideal gas law does explain hot air at surface and cooler air as it becomes less dense higher up. Zero need for 'green house gas' - still waiting for experiment that demonstrates doubling CO2 raises air temp 2.7F to 8.1F as required by mann made warming theory
