But they did heat up the dust, causing it to radiate at infrared wavelengths.

Also in the mid-1990s, another group of scientists proposed the now widely accepted mechanism for how lakes can form under glaciers: Heat radiating from Earth's interior is trapped under the thick, insulating ice sheet, and pressure from the weight of all the ice above it lowers the melting point of the ice at the bottom.

There are still ways to make the hypothesis work: a megastructure swarm might radiate its gathered energy away as radio or laser signals instead of heat; it might not form a spherical swarm but a ring precisely aligned with our line of sight; it might use technology beyond our understanding of physics that emits no heat at all.

«In theory, if you know how much energy is coming in from the sun, and how much is reflected or radiated away, the difference is how much is heating or cooling the planet,» says Adam Szabo, a heliophysicist at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

The rocks look different because of the amount 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.

The surface of the Earth radiates as a blackbody at its temperature which is continually changing because it is being heated by the sun, or it is cooling during the night.

Jyl saw that such an outburst was as close to a declaration of love for the animal as the old man would be capable of uttering, and the three of them looked down at the massive animal, whose body heat they could still feel radiating from it — the twin antlers larger than any swords of myth, and the elk's eyes closed, and still only what seemed like a little blood dribbling down the left shoulder, from the exit wound — the post-rut musk odor of the bull was intense — and all Jyl could say was «I'm sorry.»

Their body's are much better at insulating them from the cold than radiating excess heat away.

At present we're not radiating out quite as much as we take in, so there's heat energy building up in the system.)

There's also a number of interesting applications in the evolution of Earth's atmosphere that branch off from the runaway greenhouse physics, for example how fast a magma - ocean covered early Earth ends up cooling — you can't lose heat to space of more than about 310 W / m2 or so for an Earth - sized planet with an efficient water vapor feedback, so it takes much longer for an atmosphere - cloaked Earth to cool off from impact events than a body just radiating at sigmaT ^ 4.

The whole issue is that any level above what is often called the «effective radiating level» (say, at ~ 255 K on Earth) should start to cool as atmospheric CO2 increases, since the layers above this height are being shielded more strongly from upwelling radiation... except not quite, because convection distributes heating higher than this level, the stratosphere marks the point where convection gives out and there is high static stability.

And I recall one can make ice in the desert the same way; a concentrating solar power plant could also create a «cold reservoir» by radiating heat away from some storage material at night, then dumping waste heat into that in the daytime, perhaps.

At the same time there is a lot of extra heat (~ 5 W / m2) radiated back to space.

The skin layer planet is optically very thin, so it doesn't affect the OLR significantly, but (absent direct solar heating) the little bit of the radiant flux (approximatly equal to the OLR) from below that it absorbs must be (at equilibrium) balanced by emission, which will be both downward and upward, so the flux emitted in either direction is only half of what was absorbed from below; via Kirchhoff's Law, the temperature must be smaller than the brightness temperature of the OLR (for a grey gas, Tskin ^ 4 ~ = (Te ^ 4) / 2, where Te is the effective radiating temperature for the planet, equal to the brightness temperature of the OLR — *** HOWEVER, see below ***).

So the day will lengthen, more heat will radiate away at night, and the planet will cool again.

Most of these things increase the temperature at the measuring instrument at least part of the year: pavement and walls reflect heat towards it, heated buildings radiate heat, and there are even airconditioning units venting hot air at the instruments at some sites.

Some 99.5 % of the hurricane force cause no harm and is naturally dissipated — every second, some 2 million metric tons of air are circulated in, up, and out of the hurricane — where heat energy is radiated to empty space — which every day equals, the energy released by the fusion of four hundred 20 mega-ton hydrogen bombs (See, Rice University's Hurricane Trivia at Houston TeacherTECH Archives).

DirkH I am sure that everything at a temperature above 0K radiates heat even the non GHG's.

Due to the earth's spherical shape and orbital effects, annual incoming solar radiation at the poles is so low, polar regions always radiate more heat back to space than is ever absorbed locally.

Basically, as fast as heat loiters about on our planet's surface, it either radiates off to space or Water will pick it up and carry it to the upper layers of our atmosphere, where it will change form from gas to liquid or solid giving off heat to space while being super cooled at the same time.

At the same time there was an increase in IR — more heat power flux being radiated into space — planetary cooling.

Part way there, but no quantitation yet: of the 3.77 W / m ^ 2 radiated back dowwnard, most goes to increased rate of evaporation of the water at the surface, and much less goes to increased mean temp increase at the surface; hence increased rate of non-radiative transfer of heat from surface to upper atmosphere, slight increase in rainfall as hydrological cycle is faster, and slight increase in cloud cover.

And after that, we can look at whether maybe greenhouse gasses like CO2 could be trapping some of the heat the earth is radiating, thus slowing down the rate the earth cools at.

CO2 radiation at high above is cold (depends on altitudes, latitudes, and longitudes, say from 0degreeC to -60 degreeC) can not radiate net heat back to the Earth which is at a higher temperature.

Unless you are going to deny the earth heats the sun at all, then it makes no difference HOW the sun heats the earth, the result is the still the same — the earth then radiates all / some of this heat, which heats greenhouse gasses, which in turn return some of this heat to the earth.

An atmosphere that is perfectly transparent to incoming and outgoing radiation can not radiate and all its heat content comes from conduction from the surface and is transported through the atmosphere solely by convection with no loss of energy to space except for the tiny fraction of atoms at the top of the atmosphere that exceed escape velocity.

For a much more complete Earth energy budget — data on ocean heat, solar radiance and energy radiated at the top of the atmosphere is required.

Birkeland currents are interesting, although they seem to be a possible correction to direct solar irradiance only at the poles and only in the ionosphere, which is already enormously hot — between 1500C and 2500C — but so tenuous that you wouldn't feel heat if you stuck your arm out into the near vacuum of the ionosphere, you'd feel intense cooling as your blood started to boil and ordinary thermometers would radiate heat away faster than they would equilibrate (and hence would read very cold temperatures).

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 problem with the «not radiating» misstep is that it supports the notion that heat somehow «knows» whether or not it is aiming towards a hotter surface, then concludes it will not leave because it is hotter at the other end.

The black layers that bound the gas at the top and the bottom will radiate heat from the warmer to the cooler surface until they are in equilibrium, speeding the achievement of isothermal equilibrium.
