Sentences with phrase «infrared effects of greenhouse gases»

That gives you some idea of the basic nature of infrared effects of greenhouse gases, but it still won't address some of the subtler points concerning radiative transfer and the effect of band saturation — except insofar as band saturation is used in the explanation of why the radiative effect of CO2 is roughly logarithmic.

Not exact matches

Greenhouse Effect: The heating of the surface of the earth due to the presence of an atmosphere containing gases that absorb and emit infrared radiation.

We all have been told that the greenhouse effect is due to the absorption of outgoing infrared radiation by greenhouse gases such as carbon dioxide in the atmosphere.

Radiative - covective models put the surface albedo, gas composition and their infrared absorption together with the solar irradiation into account, this gives a first guess of the top of troposphere, surface temperature and greenhouse effect (= surface temperature — radiation temperature).

Memphis — I have not ducked this — I have been explaining it... It matters because the AGWScienceFiction Greenhouse Effect is built on pretending that the only measurements of longwave infrared aka thermal infrared aka heat, «come from the atmosphere from greenhouse gasesGreenhouse Effect is built on pretending that the only measurements of longwave infrared aka thermal infrared aka heat, «come from the atmosphere from greenhouse gasesgreenhouse gases» --

Because, all the real world measurements taken of downwelling longwave, thermal, infrared are now attributed as «from the atmosphere» and not from the Sun direct, beam, and therefore bounced back by these claimed greenhouse gases and so real rises in amount, as for example in the recent warming period we had from the Sun's activity, are fraudulently attributed to Greenhouse Effect backgreenhouse gases and so real rises in amount, as for example in the recent warming period we had from the Sun's activity, are fraudulently attributed to Greenhouse Effect backGreenhouse Effect backradiation.

So, for example, the Sun's effects on the recent «global warming» are said to be of no significance, that it's all due to the greenhouse gas increase absorbing and radiating back / holding in blanket, the infrared heat upwelling from the surface.

GREENHOUSE EFFECT Greenhouse gases in the atmosphere (such as water vapor and carbon dioxide) absorb most of the Earth's emitted longwave infrared radiation, which heats the lower aGREENHOUSE EFFECT Greenhouse gases in the atmosphere (such as water vapor and carbon dioxide) absorb most of the Earth's emitted longwave infrared radiation, which heats the lower aGreenhouse gases in the atmosphere (such as water vapor and carbon dioxide) absorb most of the Earth's emitted longwave infrared radiation, which heats the lower atmosphere.

In the «simple physics» version of the greenhouse effect theory, infrared - active gases are supposed to «trap» heat in the atmosphere, because they can absorb infrared light.

I have spent my professional life studying the interactions of visible and infrared radiation with gases — one of the main physical phenomena behind the greenhouse effect.

I guess you're saying there shouldn't be??? Anyway, according to the version of the greenhouse effect theory used by the climate models, the greenhouse gases should be altering this natural temperature profile by changing the rates of «infrared cooling» from different altitudes.

If the greenhouse effect theory were true then increasing the concentration of carbon dioxide in the atmosphere should increase the average temperature in the troposphere, because carbon dioxide is an infrared - active gas.

In crude terms, the greenhouse effect theory predicts that temperatures in the troposphere will be higher in the presence of infrared - active gases than they would be otherwise.

There seems to be a popular perception that the greenhouse effect and man - made global warming theories can not be tested because «we only have one Earth», and so, unless we use computer models, we can not test what the Earth would be like if it had a different history of infrared - active gas concentrations.

Because of AGW is been changed to «shortwave only in» in order to claim that any real world measurements of downwelling longwave infrared are from «backradiation from greenhouse gases in the atmosphere», because there is no other source in the AGW Greenhouse Effect energreenhouse gases in the atmosphere», because there is no other source in the AGW Greenhouse Effect enerGreenhouse Effect energy budget.

Had the infrared radiations of the greenhouse gas effect existed, we would have already captured it in our infrared telescopes.

The observed outgoing longwave emission (or thermal infrared) of the globe is increasing, contrary to what models say on a would - be «radiative imbalance»; the «blanket» effect of CO2 or CH4 «greenhouse gases» is not seen.

It is because the air has a vertical temperature lapse rate and a thickness much above the average infrared photon path length that the greenhouse effect exists and increases with the concentration of the greenhouse gases: see «The atmospheric greenhouse effect is more subtle than you believe» in La Météorologie (n ° 72 February 2011)

4 Greenhouse Effect Certain atmospheric gases trap some of the infrared radiation that escapes from the Earth, making the Earth warmer than it would be otherwise.

The simple remark is that increasing concentration of a greenhouse gas does two things: it increases absorption of infrared coming from warm layers below (a warming effect) but it also increases emission of infrared from the layer of atmosphere in question.

That downwelling happens constantly even at night and worldwide and it has been theorised by global warming proponents that extra downwelling infrared from more greenhouse gases is at the heart of the proposed climate effect from human sources of CO2.

When more than one greenhouse gas simultaneously absorb in the infrared their total combined absorption effect is not the arithmetic sum of their individual absorption effects.

1) The fundamental «greenhouse effect» basic physics that Tyndall describes as quoted above from a century ago — some gases, including water vapor and carbon dioxide, are transparent in the human visual range, but are not transparent to a range of infrared.

My reply: — Global average atmospheric greenhouse - gas optical thickness is the measure of the infrared absorptive capacity of the atmosphere — that is, of the greenhouse effect.

Past interglacial warming were triggered by sharp spikes in solar irradiation associated with the Earth's position relative to the sun (Milankovic cycles), with consequent feedback release of greenhouse gas (CO2, CH4) from the oceans and the biosphere, resulting in atmospheric infrared radiation effects and in melting of ice sheets, which amplify global warming.
