Joe Reiss, vice president of marketing at manufacturer American Science and Engineering (AS&E) in Billerica, Mass., says low - atomic - number elements such as carbon, oxygen, hydrogen and nitrogen — common constituents of explosives — create a strong scattering effect visible in images that operators monitor on a screen yet discernible from the organic molecules in the human body.

Now, if you have all this very cold, nearly freezing water surrounding these ice caps, sucking up carbon dioxide out of the polar atmosphere, at nearly the highest possible rate, 30 times faster than oxygen, and 70 times faster than nitrogen, doesn't it stand to reason that the air that remains might just have a lot less carbon dioxide in it than the atmosphere across the rest of the planet?

At 300K (27 C) ground state CO2 molecules are continually colliding with oxygen, nitrogen and other molecules.

Auroral emissions typically occur at altitudes of about 100 km (60 miles) and are often green, white, or reddish in colour depending on what species (atomic oxygen, molecular oxygen, or nitrogen, respectively) is primarily emitting light.

Starting from 187 ppmv (typical for 20 KY), doubling four times brings the CO2 up to 3000 ppmv (typical for 60 MY) or 0.3 %, still a trace gas compared to water vapor at most locations, let alone oxygen and nitrogen.

As I've said many times before, my theories lead to the conclusion that it is not the total amount of CO2 in the atmosphere that is important, but the proportion of new hot CO2.If you doubt that, just take a look at the specific heats of oxygen, nitrogen and carbon dioxide

Petra December 16, 2012 at 2:12 am said:» That oxygen and nitrogen may insulate the earth against some cooling, does not preclude greenhouse gasses from being warmed by IR»

The liquid condensed at the bottom evaporates creating local cooling and rises; the way ocean water and all water does from the surface as an enormous pool of evaporative phase change refrigerant for the surface (and the atmospheric bath of nitrogen / oxygen).

The minus - 18 °C figure quoted by AGWScienceFiction fisics in its fake Greenhouse Effect energy budget, has been stolen from real physics where it refers to the Earth without any atmosphere at all, and that is predominantly nitrogen and oxygen.

They called carbon dioxide, and oxygen and nitrogen, «ideal gases», and said they behave as per basic ideal gas description (pre Van der Waals), in other words, they have taken all the properties and process of real gases out of their «gases» and reduced them to hard dots with no mass, (no volume, weight or attraction and therefore nothing to be subject to gravity), and they say these travel at great speeds through empty space as per ideal gas, bouncing off each other in elastic collisions and so «thoroughly mixing» that they can't be unmixed (without an immense amount of work being done, so for all practical purposes can not be unmixed).

Real World Earth with full atmosphere of mainly nitrogen and oxygen, 15 °C Earth without any atmosphere at all, mainly nitrogen and oxygen, minus 18 °C, compare with the Moon Earth atmosphere of mainly nitrogen and oxygen, but without water, 67 °C, think deserts

In which case, does the oxygen and nitrogen in the earth's atmosphere emit significant amounts of radiation (at night for example)?

Carbon dioxide and nitrogen and oxygen have been reduced to a non-existant entity, a concept of a gas with no properties and processes, as they've done with «all electromagnetic energy is the same and all create heat on being absorbed», making them ideal gases without properties and processes in the Greenhouse Effect — they have actually become hard dots of nothing without volume travelling at great speeds under their own molecular momentum bouncing off each other in elastic collisions, as the description of the imaginary ideal gas in a container of real world physics textbooks.

It's at this tiny electronic transition level that visible gets bounced around all over the sky when the electrons of nitrogen and oxygen absorb it and then spit it out.

But pollution also covers hundreds of chemicals which are fine or even beneficial at low levels but which if released in large quantities or in problematic circumstances cause «harm» — like phosphorus (grows your veges but also leads to toxic cyanobacterial blooms which kill cattle), nitrogen (grows crops kills many native species of plants and promotes weed growth costing farmers), copper (used as an oxygen carrier by gastropods but in high concentrations kills the life in sediments which feed fish), hormones like oestrogen (essential for regulating bodies but in high concentrations confuse reproductive cycles especially with marine life) or maybe molasses from a sugar mill (good for rum but when dumped into east coast estuaries used to cause oxygen sag in estuaries leading to massive fish kills).

First, put your hand in front of a heat gun blowing hot air heated to 300C, and then tell me that the oxygen, nitrogen, carbon dioxide, and all the rest are actually at different temperatures.

In other words, you are suggesting that if our atmosphere consisted only of nitrogen, oxygen and argon, that the temperature at the Earth's surface would be the same as that of an asteroid.

Ira — regarding your summary comment 4) at May 8, 2011 at 7:51 pm my comment — NO, the atmosphere does NOT emit LWIR across a distribution of wavelengths like a blackbody, see my earlier comment at Dave in Delaware says: May 8, 2011 at 7:00 am Ira Glickstein, PhD says: «4) As I understand it, the ~ 15μm radiation from the Surface to the Atmosphere is absorbed by H2O and CO2 molecules which, when excited, bump into nitrogen and oxygen and other air molecules, and heat the air.

Instead, presumably, CO2 is fairly evenly distributed all through the atmosphere - all around our heads and arms and legs - all the way up higher into the troposphere at every location in the troposphere - absorbing and radiating some of its absorbed heat to the also all - surrounding nitrogen / oxygen.

Alastair, I think your mistake is in thinking that because the nitrogen and oxygen don't radiate, there's no radiation from a given level at all.
