From what I gather, the ocean, being the huge black body it is, emits a heck of a lot of radiation, a small portion of that gets absorbed by the occasional water vapor molecule (which probably also came from the ocean) or CO2 molecule (which also may have come from the ocean).

The World Health Organization (WHO) estimates that the typical absorbed dose of mercury from amalgams is one to twenty - two micrograms per day, with most values in the range of one to five micrograms per day.16 Various factors, including gum chewing and bruxism, can increase these exposures to an upper range of about one hundred micrograms per day.7 Preliminary evidence also suggests that certain types of electromagnetic radiation, including EMR from mobile phones and from magnetic resonance imaging (MRI) may increase the release of mercury vapor from dental amalgams.17

The addition of the silver and gold layers widens that bandgap meaning that the new solar cells can absorb and convert more of that UV and infrared radiation into electricity, which not only makes the technology more efficient, but also makes it much stronger and resilient.

We also know quite accurately the spectral absorption characteristics for the absorbing gases, and how cloud and aerosol particles interact with thermal radiation.

«Arrhenius and Chamberlain saw in this [variations in carbon dioxide] a cause of climate changes, but the theory was never widely accepted and was abandoned when it was found that all the long - wave radiation absorbed by CO2 is also absorbed by water vapor.

BTW, For the radiation fans, they could look at the portion of the solar spectrum absorbed by water vapor that also penetrates below 10 meters in the ocean.

However, it also shows that as the radiation moves into the infra - red, the ability of the deeper ocean to absorb heat rapidly diminishes.

Increased amounts of gases such as carbon dioxide make the atmosphere absorb long - wavelength radiation from the surface more strongly and also emit more radiation back down towards the surface.

«As an object radiates energy at a rate given by Equation 20.18 [P = o A e T ^ 4], it also absorbs electromagnetic radiation.

Less well appreciated is that clouds (made of ice particles and / or liquid water droplets) also absorb infrared radiation and contribute to the greenhouse effect, too.

Plankton is largest CO2 absorber, but also oceans are near or largest (by far largest in the more distant past) CO2 emitters, so if CO2 happen to be an important factor than: High UV / radiation = reduction in plankton = less CO2 absorbed = warming, reverse holds true.

Disappearing Arctic sea ice — summer ice extent was at its lowest level in recorded history in 2007 and almost hit that level in 2008 — also will warm the Arctic Ocean, since a dark, ice - free sea absorbs more solar radiation than a white, ice - covered one.

Ozone is abundant here and it heats the atmosphere while also absorbing harmful radiation from the sun.

Also contributing to the warmer urban atmosphere is the blanket of pollutants and water vapour that absorbs a portion of the thermal radiation emitted by the Earth's surface.

Another problem is that gases that absorb LWIR radation also emitt LWIR radiation.

The AGWSF meme for the plebs is that «all electromagnetic radiation is the same» and «all create heat on being absorbed», and it also provides «rebuttal memes» for their apologetics teams, «haven't you heard of conservation of energy?»

The gases in the bottles are being heated by conduction but CO2 is also absorbing significant IR in the 2.7 micron band directly from the radiant emissions from the lamp as glass transmits a significant proportion of the radiation at this wavelength and significant IR from the heated glass in the ~ 15 micron bandwidth.

However, mixtures of gases (even poor absorbers) are better, not only because of different absorption spectra, but also because of the inter-species collisions (which to the radiation look like asymmetrical molecules).

We also briefly discuss the complex problem of estimating surface UV radiation in presence of UV - absorbing aerosols.

I would also invite you to think about how perfect LTE could possibly be observed if it did exist; any device you use to measure the thermal radiation or the distribution of velocities or the population of excited states must itself be at a different effective temperature from the gas in question, and must absorb energy from it, disturbing the very equilibrium you are trying to observe.

It also absorbs and sends back to space some of the Sun's incident radiation which is in the IR spectrum, hence also having a cooling effect in this manner.

Ken says the fact that CO2 absorbs «ir» (infra - red, also called «longwave») radiation, is evidence that humans are warming the climate.

The error made in the experiment was that c02 was way saturated!?! [i] JAMES: From doing my own digging around I have also had trouble finding the science that «proved» that CO2 absorbs infrared radiation.

The darker surface of plants compared with sand also absorb more solar radiation, which can create convection and turbulence in the atmosphere which might create rainfall.

And any 15 um radiation from the even warmer ground is ALSO absorbed by the intermediate layers.

(It's also 8 times larger than the amount of incident solar radiation absorbed by the atmosphere).

Since to me (and many scientists, although some wanted a lot more corroborative evidence, which they've also gotten) it makes absolutely no sense to presume that the earth would just go about its merry way and keep the climate nice and relatively stable for us (though this rare actual climate scientist pseudo skeptic seems to think it would, based upon some non scientific belief — see second half of this piece), when the earth changes climate easily as it is, climate is ultimately an expression of energy, it is stabilized (right now) by the oceans and ice sheets, and increasing the number of long term thermal radiation / heat energy absorbing and re radiating molecules to levels not seen on earth in several million years would add an enormous influx of energy to the lower atmosphere earth system, which would mildly warm the air and increasingly transfer energy to the earth over time, which in turn would start to alter those stabilizing systems (and which, with increasing ocean energy retention and accelerating polar ice sheet melting at both ends of the globe, is exactly what we've been seeing) and start to reinforce the same process until a new stases would be reached well after the atmospheric levels of ghg has stabilized.

Anyone in their right mind also knows that radiation is absorbed by everything as a function of its own material properties and angle of incidence, not the temperature of the emitting body.

But if it is not radiating it is also not absorbing (radiation and absorption of energy are controlled by the same factor — a consequence of Kirchoffs law) hence the statosphere can not be an opaque (or «steel») shell.

If the tropopasue is radiating strongly to space it will also be absorbing strongly any radiation received from below, so it would be blocking radiation emanating from lower in the troposphere.

It absorbs solar radiation converting it to heat and then warming the atmosphere, It also dissolve in the oceans lowering the pH (makes them more acidic) which interferes with phytoplankton, fish reproduction the production of coral and mollusk shells.

A part of what the ground and oceans and lower atmosphere absorb also leaks outward through the atmosphere in the form of infrared radiation.

The model also does not take into account dust and water in the form of clouds which both hold great quantities of CO2 and which takes it directly and quickly into the carbon life cycle at ground level and uses it up and none of this directly absorbed solar radiation is taken into account in the model.
