At night the earth radiates to the sky; this flux came to be termed «nocturnal radiation» — though as Wells himself noted it is not strictly nocturnal:

Radiation of heat by the earth to the heavens must exist at all times; but, if the sun be at some height above the horizon, the degree of which is hitherto undetermined, and probably varies according to the season, and several other circumstances, the heat emitted by it to the earth will overbalance, even in places shaded from its direct beams, that which the earth radiates upwards.

Again: The Earth radiates from the top of the atmosphere and that's where you find exactly the temperature needed to radiate enough.

Once radiative equilibrium is reestablished, this is a very helpful picture because we have just shifted the altitude higher from which the earth radiates but have kept the same temperature which means the surface must be warmer because it is connected by the lapse rate.

We then raise the ceiling (by adding carbon dioxide) and take note that the level in the atmosphere from which the earth radiates to space in now higher up and thus colder (on account of the fixed lapse rate).

The sun brings heat, and earth radiates heat back into space — but the numbers did not balance.

Moreover, anything that slows down the rate at which the Earth radiates to space requires that the Earth heat up so as to be able to shed the same amount of energy per unit time and increasing greenhouse gas concentrations does that.

You can't say that the earth radiates 235 watts per square meter from the center and that this amount still ends up being 235 watts per square meter at the surface.

If earth radiates 100 W / m ^ 2, then the shell will heat up and radiate 50 w / m ^ 2 inward and 50 w / m ^ 2 outward (it has twice as much area remember).

It's because it's based on the premise that the Earth radiates IR as if it were an isolated black body in a vacuum.

At the same time, the various bushes aren't producing any new leaves at all yet, and even the hazel flowers haven't really opened yet (normally the first sign of spring around here), despite sufficiently sunny days (which are followed by freezing nights because the lack of clouds mean the Earth radiates heat into the atmosphere more easily).

Anyway, even that small absorption cross section and the very low density of CO2 are enough to «catch» just about all the 15 - micron photons the Earth radiates, apparently.

-- it is not necessary for visible light to heat the earth, for it to be reradiated as IR — and anyway, by whatever wavelength, the earth * is * warmed by the sun — the earth radiates IR, which warms its greenhouse gasses

If the sun somehow warms the earth, and the earth radiates longwave that is increasingly trapped by increasing CO2, we still have an AGW situation of some or other magnitude.

Suppose there are GHG's, the earth radiates.

Worse, satellites don't actually measure temperature directly; they measure how much energy the Earth radiates, and that's converted into a temperature.

The earth radiates the solar energy it receives from sunlight into space as OLR, Outgoing Longwave Radiation.

So, ** WHICHEVER ** WAVELENGTH WARMS THE EARTH, THE RESULT IS THE SAME — THE EARTH RADIATES LONGWAVE, which warms the greenhouse gasses.

Since the Earth radiates approximately 240Wm - 2 of energy which has an effective temperature of 255K degrees, 255K to 249K is often chosen.

If the amount of energy received by the Earth from the Sun exceeds the amount the Earth radiates into space, then the only thing the Earth can do is increase its temperature, which in turn will increase the amount of radiation into space.

Meanwhile, Earth radiates from its whole surface area, which is that of a sphere — 4 π R ^ 2.

Global warming is the result of a greenhouse gas - caused imbalance between incoming solar energy and heat that the Earth radiates away to space.

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.

Yet he has ignored the fact that energy from the sun is constantly being added to the system which does indeed make the Earth radiate at a higher temperature.

Well, consider the situation without GHGs and ignore the Earth radiating energy for the moment.

Not exact matches

What he presents is the view of a planetarian community of nature and humanity, of humans among themselves, of humanity and God; it is (national) citizenship, co-citizenship and citizenship of the Earth.23 Against the type of globalization radiating from the West he can say: «The West appears to us, today, more and more like a tragic accident in the global process of humanity.

Because Earth and the moon were tidally locked from the beginning, the still hot Earth — more than 2500 degrees Celsius — radiated towards the near side of the moon.

«Of these, the only quantity that can be measured is that which is radiated through the earth.»

Date: December 26, 2015 Mass of first black hole: 14.2 solar masses Mass of second black hole: 7.5 solar masses Merged mass: 20.8 solar masses Energy radiated as gravitational waves: 1 solar mass Distance from Earth: 1.4 billion light - years

Date: September 14, 2015 Mass of first black hole: 36.2 solar masses Mass of second black hole: 29.1 solar masses Merged mass: 62.3 solar masses Energy radiated as gravitational waves: 3 solar masses Distance from Earth: 1.4 billion light - years

«The total energy from an earthquake includes energy required to create new cracks in rock, energy dissipated as heat through friction, and energy elastically radiated through the earth,» reports the U.S. Geological Survey's Earthquake Hazards Program.

The so - called greenhouse gases — mainly water vapor and carbon dioxide — make the planet warm and habitable by trapping solar heat as it radiates back off the Earth.

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.

«Life on Earth has radiated into every conceivable — and in some cases almost inconceivable — ecological niche,» says Chris Impey of the University of Arizona in Tucson, US.

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.

Using engineered nanophotonic materials the team was able to strongly suppress how much heat - inducing sunlight the panel absorbs, while it radiates heat very efficiently in the key frequency range necessary to escape Earth's atmosphere.

Scientists say that after carbon dioxide, methane is the most important contributor to the greenhouse effect, in which gases in the atmosphere trap heat that would otherwise radiate from Earth.

Indeed, Earth is inside a very bright solar system: sunlight scattered by all the dust in the plane of Earth's orbit creates the zodiacal light radiating across the optical spectrum down to long - wavelength infrared.

The solar energy that falls on the earth warms the surface and is ultimately radiated back into space.

CO2 absorbs some wavelengths of the infrared light now being radiated from Earth's surface.

Thus when the Earth is radiating with a greater intensity than the back radiation from the air, then the excess radiation will be absorbed by the air molecules, and the air will warm.
