The next most abundant gases — water vapor and carbon dioxide — do absorb a portion of
the infrared heat radiated by the earth's surface, thereby preventing it from reaching space.
Currently, the amount of
infrared heat radiated back to space is slightly less than what we absorb from the sun due to the increase in greenhouse gases.

infrared wavelengths.
Spitzer was sent so far out because its delicate
infrared - sensitive instruments must be kept at a frigid temperature just above absolute zero, and it is easier to maintain that temperature by operating far from the

radiates from the surface of our planet.
The cooling mechanism involves the absorption of
heat by the haze particles, which then emit
infrared radiation, cooling the atmosphere by
radiating energy into space.

heats the Martian surface, each type of rock
radiates back a unique pattern of

infrared light they
radiate into space, similar to the way a brick wall
heats up during the day and gives off its
heat at night.
Besides, different surfaces
radiate different amounts of
heat at
infrared wavelengths owing to a material characteristic known as emissivity.
Infrared heat is
radiated by the cedar wood and will warm your feet, help with your joints and increase sweating.
Are the episodes thought to be actual changes in the amount of
heat being
radiated by the planet (because the surface of the ocean gets warmer and cooler, does the actual
infrared flux from the top of the atmosphere then change as a result)?
An incandescant light bulb
radiates around 5 % visible light, the rest it
radiates as
heat, thermal
infrared aka longwave
infrared.
They know that the
heat we get from the Sun is the Sun's thermal energy radiated to us in thermal infrared, it's called HEAT transfer by radiation, and you've taken that out of your Greenhouse Effect energy budg
heat we get from the Sun is the Sun's thermal energy
radiated to us in thermal
infrared, it's called
HEAT transfer by radiation, and you've taken that out of your Greenhouse Effect energy budg
HEAT transfer by radiation, and you've taken that out of your Greenhouse Effect energy budget..
The actual
heat we feel from the Sun is the Sun's thermal energy
radiating out to us, the Sun's visible / shortwave light are not thermal and are physically incapable of
heating matter as real thermal
infrared heat radiation does.
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.
So the first explanation for how this works, the original, is the now classic «greenhouse glass like barrier stopping longwave from the Sun from entering the atmosphere while visible travels through and is absorbed
heating the Earth's surface which then
radiates out thermal
infrared, longwave.
So Myrrh says: «This invisible
heat radiating to us from the Sun is what Herschel discovered, he called it «dark light», we now call it thermal
infrared.
What is clear is that the
heat a human
radiates, a fire, or sun is same thermal
infrared.
This invisible
heat radiating to us from the Sun is what Herschel discovered, he called it «dark light», we now call it thermal
infrared.
In the real world an incandescent lightbulb
radiates around 5 % visible light and 95 % thermal
infrared,
heat.
Just as an incandescent bulb
radiates out 95 %
heat which is thermal
infrared, and only 5 % visible light.
So it can pretend that «all downwelling measurements of thermal
infrared, longwave, are the result of greenhouse gases trapping the upwelling
heat and
radiating it back to Earth's surface», as SkepticalScience explains further:
They have taken out the direct
heat radiating to us from the millions of degrees Corona, thermal
infrared.
I point out that the energy budget cartoon you work to claims that shortwave from the Sun is the only source of directly
heating Earth's land and oceans for it to
radiate out the amount of thermal
infrared,
heat, claimed, and you come back with «it's not completely zero» and the idiocy of Tim's so called experiment to prove shash might be there at the cold depths..?
The AGW claim from the comic cartoon KT97 and kin The Greenhouse Effect says that Shortwave, (near UV, visible and near
infrared, but mostly visible)
heats up land and oceans, that no longwave
infrared from the Sun gets through the invisible undefined and unexplained barrier said to be like the glass of a greenhouse, and then the Shortwave
heated land and oceans
radiate out longwave
infrared, (which in real physics is
heat, also called thermal
infrared).
In the experiment, which was for pure gases and vapors, the absorbed and
radiated infrared radiations came from sources of
heat which included
heated oil to 250 °C and
heated copper ball to low redness.
Measuring with a spectrometer what is left from the radiation of a broadband
infrared source (say a black body
heated at 1000 °C) after crossing the equivalent of some tens or hundreds of meters of the air, shows that the main CO2 bands (4.3 µm and 15 µm) have been replaced by the emission spectrum of the CO2 which is
radiated at the temperature of the trace - gas.
It is considered a greenhouse gas as it traps
heat (
infrared energy)
radiated by the Earth into the atmosphere and thereby contributes to the potential for global warming.
If you put a mirror a few feet away from an
infrared source, say a
heat lamp, the mirror
radiates energy as visible white light and LWIR, both radiative energy, but that won't increase the temperature of the
heat lamp any.
Of course, Carbon Dioxide doesn't trap
heat — it actually «traps»
infrared radiation by back -
radiating it to the earth.
For the Earth's temperature to be in steady state so that the Earth does not rapidly
heat or cool, this absorbed solar radiation must be very nearly balanced by energy
radiated back to space in the
infrared wavelengths.
After a few
infrared measurements on summer nights showed that the amount of
heat being
radiated from the atmosphere was much less than some climate models predicted, he began an intensive study resulting in his own computer simulations based on available atmospheric data and well - known laws of
infrared physics.
The idea is: outgoing
infrared radiation stimulates atmospheric CO2 which
heats up and «back
radiates» to the earth... making us hotter.
