Sentences with phrase «radiation by carbon dioxide»

The good news is (at least from the perspective of science) that the role of carbon dioxide in climate change is very well established — at the theoretical level in terms of quantum physics, at the experimental level in terms of the study of the absorbtion and re-emission of radiation by carbon dioxide, at the numerical level (when equations get a little too complicated — but a good approximation can result from intensive computation by means of our fairly advanced computers), in terms of historical trends going back more than 500,000 years — and countless studies.

It is necessary to understand here that laboratory demonstrations of the absorption of infrared radiation by carbon dioxide are not proof of the greenhouse effect.

Although Solar radiation and lightning (which has been detected by the ESA's Venus Express probe in 2007) should be producing large amounts of carbon monoxide (CO), the gas was found to be scarce, as if something was removing it (such as hydrogenogens, diverse bacteria and archaea that grow anaerobically utilizing CO as their sole carbon source and water as an electron acceptor to produce carbon dioxide and molecular hydrogen as waste products).

Greenhouse gases (which prevent dispersal of heat generated by the planet's surface, after this receiving solar radiation) of higher concentration on Earth are carbon dioxide (CO2), methane (CH 4), nitrous oxide (N2O), Compounds of chlorofluorocarbon (CFC) and water vapor (H2O).

As to the absorption of long - wave radiation from the earth's surface, while it may be true that carbon dioxide and water together do absorb certain frequency ranges of that radiation, I don't think that that matters a whole lot because most of the heat from the surface is transported to the top of the troposphere by conduction, convection and latent heat of vaporization of water during the day.

Incident solar radiation (mostly in the 2.7 micron band) is absorbed by carbon dioxide at various levels in the atmosphere.

At this point, very simple physics takes over, and you are pretty much doomed, by what scientists refer to as the «radiative» properties of carbon dioxide molecules (which trap infrared heat radiation that would otherwise escape to space), to have a warming planet.

Thus, if adding carbon dioxide reduces the ability of the earth system to cool by emitting thermal radiation to space, the positive feedbacks will further reduce this ability.

Leaf area index, which is also enhanced by increasing atmospheric carbon dioxide, was the second most important factor, contributing an additional 21.8 percent, followed by climate change (precipitation and air temperature together) and the fraction of photosynthetically active radiation, which accounted for the remaining 18.3 and 14.6 percent increase in NPP, respectively.

Increasing concentrations of greenhouse gases such as carbon dioxide and methane increase the temperature of the lower atmosphere by restricting the outward passage of emitted radiation, resulting in «global warming,» or, more broadly, global climate change.»

Ozone in the stratosphere protects earth from radiation (otherwise we would all be fried double quick) but in the troposphere it becomes a GHG, adding to the woes created by carbon dioxide, methane and nitrous oxide.

The longer wavelength (infrared) radiation created there is reflected upwards, and then is absorbed by clouds and the greenhouse gases (GHGs include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), etc.).

Here's Merriam Webster's version: Main Entry: carbon dioxide Function: noun: a heavy colorless gas CO 2 that does not support combustion, dissolves in water to form carbonic acid, is formed especially in animal respiration and in the decay or combustion of animal and vegetable matter, is absorbed from the air by plants in photosynthesis, and is used in the carbonation of beverages I know you'll all correct me if i'm wrong in stating if CO2 has no scientific facts supporting global warming based upon a factor of greenhouse gases (as opposed to solar radiation in another post, which would be defined by variations in earth, space, or similar factors), then where does science determine that CO2 «disolves in water to form carbonic acid» and is «absorbed from the air by plants in photosythesis»?

Thank you for responding... the question at hand is not about whether carbon dioxide absorbs infrared radiation: what is being asked for is the replicable experiments which verify the hypothesis (postulated by Mr. Guy Callendar et al) that adding more carbon dioxide to the atmosphere would change the height where the absorption took place.

He showed that atmospheric absorption of long - wave radiation was constant for 61 years while at the same time carbon dioxide increased by 21.6 percent.

He deduced that the cooperation of these gases has to take the form of an optimal atmospheric transmittance window for infrared radiation, such that if the concentration of one gas, say carbon dioxide, varies and changes atmospheric transmittance, the other components, such as water vapor, will have to compensate for it by changing their concentrations.

The scenarios include: «business as usual» (BAU), which assumes no mitigation efforts are made («RCP8.5»); «mitigation», which assumes an intermediate level of emissions («RCP4.5») without negative emissions; «carbon dioxide removal» («CDR»), which assumes moderate emissions with long - term CO2 removal; and «solar radiation management» («SRM»), which is the same as the CDR pathway, but also includes enough SRM to limit temperatures to 1.5 C above pre-industrial levels by 2100.

ANSWER: by «saturation» is usually meant a complete absorption of the radiation of the surface by the carbon dioxide and water vapor of the air: according to Dufresne and Treiner it is saturated and according to Pierrehumbert (Physics Today 2011) it is not; for me 0.8 (W / m ²) / 400 = 0.2 % for a doubling of the CO2 content is» nearly saturated»; 0.8 W / m ² is the additional absorption for 2xCO2 (e.g. per Hansen 1981)

In just 5 years it was responsible for a 2 % decrease in low clouds (the kind that reflect incoming solar radiation by day) which, in turn, equates to an increase in surface warming of 1.2 Wm - 2 from incident radiation — equivalent to some 85 % of the IPCC's estimate for the effect of all carbon dioxide increase since the Industrial Revolution.

it will re-emit in a range according to the rules i can't recall, but here's a nice animation: - http://www.rkm.com.au/ANIMATIONS/carbon-dioxide-global-warming.html since the electromagnetic radiation absorbed and re-emitted by carbon dioxide are in fairly closely defined ranges, i think it's fair to use the word «colour».

An increase of carbon dioxide will lower the mean radiation focus, and because the temperature is higher near the surface the radiation is increased, without allowing for any increased absorption by a greater total thickness of the gas.
