They also fail to mention that sunlight can travel tens of METRES into the water and is thus a powerful warming agent compared to the single MILLIMETRE penetration of down welling
infrared radiation from the atmosphere.
... the long wave
infrared radiation from the atmosphere has a lot to low energy (wavelength) one is not deeper than a fraction of a millimeter (10 micrometers).
Downward long - wave or
infrared radiation from the atmosphere to the surface is a vital component to warming the Earth's surface.

When the team looked at the overall balance between the
radiation upward
from the surface of the ice sheet and the
radiation both upward and downward
from the upper levels of the
atmosphere across all
infrared wavelengths over the course of a year, they found that in central Antarctica the surface and lower
atmosphere, against expectation, actually lose more energy to space if the air contains greenhouse gases, the researchers report online and in a forthcoming Geophysical Research Letters.
The visible solar
radiation mostly heats the surface, not the
atmosphere, whereas most of the
infrared radiation escaping to space is emitted
from the upper
atmosphere, not the surface.
According to Zhang, the excess
infrared radiation from haze particles in Pluto's
atmosphere should be detectable by the James Webb Space Telescope, allowing confirmation of his team's hypothesis after the telescope's planned launch in 2019.
It's not totally about how much
infrared from the surface that is blocked (currently about 90 % of surface emissions is absorbed by greenhouse gases), its also about the height within the
atmosphere from which
radiation escapes.
Depending on the mass of the planets and their distance
from the brown dwarf, we should get Io / Europa analogues or, if it has enough mass to hold onto an
atmosphere, we could get something different: a world that thanks to tidal heating (and
infrared radiation) keeps the surface water liquid.
The amounts that are in Pluto's
atmosphere are enough to absorb
infrared radiation (heat)
from the sun and warm the upper
atmosphere.
ABSTRACT «We investigate the interaction of
infrared active molecules in the
atmosphere with their own thermal background
radiation as well as with
radiation from an external blackbody radiator.
CO2 reduces the rate at which the
atmosphere loses its energy to space via
infrared radiation, which in turn reduces the flow of energy
from the Earth's surface to the
atmosphere.
The same issues that are bugging you (or your skeptical acquaintance) are perfectly well illustrated, indeed better illustrated, by the heating of bare, dry rock
from solar
radiation and
from infrared coming down
from the
atmosphere.
The spacecraft's Atmospheric

The heat caused by
infrared radiation is absorbed by greenhouse gases such as water vapor, carbon dioxide, ozone and methane, which slows its escape
from the
atmosphere.
The spectrum of thermal
infrared radiation is practically distinct
from that of shortwave or solar
radiation because of the difference in temperature between the Sun and the Earth -
atmosphere system.
Their container for their empty space
atmosphere being the non-existant glass of their greenhouse which prevents longwave
infrared direct
from the Sun entering, which is heat
radiation, and for which they have substituted shortwave mainly visible light to heat their imaginary Earth, impossible in the real world.
The Met Office state «The «greenhouse effect» is the way the
atmosphere traps some of the energy we receive
from the Sun (
infrared radiation or heat, ultraviolet and visible light) and stops it being transmitted back out into space».
So water dances at many speeds,
from the unimaginable fast vibrations of its molecules responding to thermal
infrared radiation, to the moment - to - moment dance of its phase changes in response to temperature changes, to the week - long dance of its vapor in and out of the
atmosphere, to the slow geological pavanes of rock, air and life, of which it too forms an inextricable part.
Less often, the CO2 will re-emit
infrared radiation in a random direction, either to be absorbed again, or to escape
from Earth's
atmosphere altogether.
A sea surface temperature increase in the tropics would result in reduced cirrus clouds and thus more
infrared radiation leakage
from Earth's
atmosphere.
Traditional anthropogenic theory of currently observed global warming states that release of carbon dioxide into
atmosphere (partially as a result of utilization of fossil fuels) leads to an increase in atmospheric temperature because the molecules of CO2 (and other greenhouse gases) absorb the
infrared radiation from the Earth's surface.
Tom Vonk is correct when he says that the following statements are over-simplifications and need corrections (in caps): «CO2 absorbs AND EMITS the outgoing
infrared energy and warms the atmosphere TO A HIGHER TEMPERATURE THAN IT WOULD HAVE WITHOUT CO2» — or — «CO2 traps part of the infrared radiation between ground and the upper part of the atmosphere» AND IS THE MAJOR SOURCE OF INFRARED RADIATION FROM THE UPPER ATMOSPHERE T

This quantity represents the difference in the intensity of the long - and short - wave
infrared radiation at these two wavelengths that travels upward
from the
atmosphere to the satellite, and it is traditionally used to differentiate between water and ice clouds.
This must result in about 85 times as much
infrared radiation from the Sun, at 3.3 microns wavelength, being sent back into space by the absorption and re-
radiation from methane molecules in the upper
atmosphere as could be re-radiated into the lower
atmosphere for
infrared radiation sourced
from the warmed Earth.
The light
from the Sun passes through the Earth's
atmosphere, which is transparent to visible light (that's why our eyes evolved to be sensitive to this kind of electromagnetic
radiation), and warms the surface of the Earth, which in turn reradiates the energy, now as
infrared radiation, because the Earth's surface isn't as hot as the Sun.
Radiation comes in
from the sun (solar
radiation at short wavelengths), and every body radiates according to its temperature (proportional to the fourth power of absolute temperature), so that on Earth we, and the surface and
atmosphere radiate at
infrared wavelengths.
Then, for the benefit of the lay reader, who would not be expected to understand the clear (to a competent physical scientist) implication of this simply - stated fact, I wrote: «This in fact indicates that the Venusian
atmosphere is heated mainly by incident

from Aseada et al. (1996) «most of the
infrared radiation from the ground was absorbed within 200 m of the lower
atmosphere, affecting air temperature near the ground ``.
The pioneer was W.H. Dines, who gave the first explicit model including
infrared radiation upward and downward
from the
atmosphere itself, and energy moved up
from the Earth's surface into the
atmosphere in the form of heat carried by moisture, Dines (1917); Hunt et al. (1986) gives a review.
The gas which absorbs the most heat (
infrared radiation) is the most effective greenhouse gas as in the
atmosphere it would absorb more
infrared coming
from the Earth's surface.
Anthropogenic global warming is caused by an increase in the amount of downward longwave
infrared radiation coming
from greenhouse gases in the
atmosphere.
The evidence here comes
from satellite measurements of
infrared radiation escaping
from the earth into outer space,
from measurements of sunlight reflected
from clouds and
from measurements of the temperature the earth's surface or of the troposphere, the roughly 10 km thick layer of the
atmosphere above the earth's surface that is filled with churning air and clouds, heated
from below at the earth's surface, and cooled at the top by
radiation into space.
more carbon dioxide in the lower
atmosphere means more little «point sources» for more absorbed EM in the
infrared part of the spectrum, (
infrared that re-radiated
from the earth's surface after sunlight hit it and got absorbed); and since point sources radiate in a spherical pattern, that means more «back
radiation» to earth, on balance... and this changes the «standing pattern» of energy flow in and out of the earth system, creating a time differential, so it starts to re-adjust...
The visible solar
radiation mostly heats the surface, not the
atmosphere, whereas most of the
infrared radiation escaping to space is emitted
from the upper
atmosphere, not the surface.

Both, however, are efficient at intercepting outgoing
infrared radiation from the Earth's surface and
atmosphere The disparity is due to the different wavelengths of incoming solar energy and outgoing
infrared energy.
The only energy it has comes
from other places... like collisions with the other atoms and molecules of the
atmosphere,
from infrared radiation and conduction
from the earth's surface.
