Sentences with phrase «earth radiates heat»

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

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).

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.

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.

I fully acknowledge that greenhouse gases can trap solar radiation so that it converted to heat and unless the heat can be radiated into space the Earth will warm.

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.

With climate and Greenhouse Gas thoeries of Global warming, it appears to me that of most interest is the interface between the Earth's atmosphere and space and the flow of radiated heat from the sun, what's reflected back from Earth's surface and the consequences of any change in that balance.

«Sunlight passes through the atmosphere largely unhindered and warms the Earth's surface; the warmed surface radiates heat and some of this radiation is absorbed in the upper atmosphere and re-emitted, about half of the re-emitted energy returning to the Earth's surface.

Heat radiated from the Earth's surface has a range of frequencies, which encompass the vibration frequencies of the gases in the atmosphere, including those of greenhouse gases such as carbon dioxide.»

99.96 % of dry air consists of gases that are about as transparent to the heat radiated by Earth to space as glass is to visible light.

As the Sun radiates heat to the Earth, different surfaces absorb the heat energy in different ways.

7 Wind As the Sun radiates heat to the Earth, different surfaces absorb the heat energy in different ways.

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.

Those with low tops bounce the Sun's energy back into space to keep us cooler, whereas high - level clouds tend to trap heat radiating upwards from the Earth.

Some heat radiates back to space or trapped in biosphere Balance determines Earth's average temperature Gases that control in atmosphere are carbon dioxide, methane, water vapor.

As increased levels of greenhouse gases such as carbon dioxide trap more solar heat radiating from the Earth's surface, less warmth reaches the stratosphere, which cools as a result.

This heat is radiated to space with the physical form change from gas to liquid or solid and this super or sub cooled water returns to Earth for further cooling.

Satellite measurements show that this lowest layer of the atmosphere is warming as greenhouse gases build up and trap heat that radiates from the Earth's surface.

that cloud response to warming acts similarly to the eye's iris, opening to let more heat radiate out to space as temperature rises and closing to hold more heat in as temperature falls, and generally supports the understanding that Earth's climate is self - regulating and therefore not prone to a «tipping point» or a «runaway greenhouse effect» or «catastrophic warming.»..

Less heat radiates into space, and Earth is warmer.»

If the earth is warmed up, perhaps it will radiate some of that heat?

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.

A warm body (the earth) radiates heat to a cool body (the atmosphere) 2.

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.

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.

Myhrr, you have simply ducked the point — it is not necessary for visible light to heat the earth, for it to be radiated out as longwave.

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:

Stefan So, skipping past the bulk of the answer that avoided the question, you're saying you DO accept that GHGs absorb longwave, including longwave radiated by the earth, and that they therefore trap heat, which results in the earth being warmed?

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.

-- 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

This heat is radiated back to the Earth.

Heat radiates from the Earth's surface via thermal or (roughly) «blackbody» radiation.

The earth does not radiate an appreciable amount of heat into space, and the «greehouse gases» do not make the atmosphere less reflective to photons raining down on us from the sun.

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.

Heat radiates away from the Earth; there's no need for mass to escape with it.

Clouds cool the planet by reflecting solar energy back to space and also trap heat and radiate it back to Earth.

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 Earth and its atmosphere radiate heat away into space.

Atmospheric Heating Atmosphere is heated from the bottom Solar energy absorbed by the Earth is re - radiated.

They radiate most of the heat that is received from the sun, so the average temperature of the Earth stays more or less constant.

Greenhouse gases trap some of the escaping heat closer to the Earth's surface, making it harder for it to shed that heat, so the Earth warms up in order to radiate the heat more effectively.

Most climate scientists agree the main cause of the current global warming trend is human expansion of the «greenhouse effect «1 — warming that results when the atmosphere traps heat radiating from Earth toward space.
