The researchers» model of early Earth is extremely simplified, he adds: Temperatures in Earth's interior were much hotter billions of years ago and the planet was geologically more «active,» with more volcanism at the surface and more churning in the mantle.

Green explained that at 300 - 700 kilometers depth, the pressure and temperature are so high that rocks in this deep interior of the planet can not break by the brittle processes seen on Earth's surface.

Thus, he concludes, a large fraction of extrasolar planets «will be the right size to keep on their surface water and possibly an atmosphere of some sort» and some will be «at the proper distance from their parent sun to maintain a suitable temperature».

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 heat that radiates from the surface of our planet.

At such proximity, the planet's surface should be baked to a theoretical temperature of 1,300 degree Celsius.

At the planet's orbital distance of only 0.014 AU from its host star, however, the surface temperature has been estimated to be around 400 ° Fahrenheit (200 ° Celsius), which is way too hot for liquid water.

Because planets either too close to or too far from their host stars will be at temperatures that cause water either to boil or to freeze, astrobiologists define a «habitable zone,» a range of orbital distances within which planets can support liquid water on their surfaces.

As Arctic temperatures rise at about double the rate of the planet as a whole, Greenland's surface has been melting at a steady clip, contributing about 30 percent of the foot of global sea level rise since 1900.

As far as I know, if the only physical mechanism under consideration is the radiative cooling of the planet's surface (which was heated by shortwave solar radiation and reradiated at longer wavelengths in the infrared) via radiative transport, additional gas of any kind can only result in a higher equilibrium temperature.

Global average air temperature near the surface is dominated by the ocean (because it covers two thirds of the planet), particularly at low latitudes.

The temperatures at the tops of high clouds are much colder than the surface, and thus reduce the energy loss of the planet better than low clouds (which emit at temperatures rather close to that of the surface).

If you question whether or not our atmosphere warms the planet, consider what the temperature should be at the surface based on the Stefan - Boltzmann Law and observe the temperatures of the atmosphereless moon.

The increased water vapour blocks long wave radiation which causes an increase in temperature of tropical troposphere at around 8K and an increase in long wave radiation, a portion of which is emitted back down to the surface of the planet to amplify the CO2 forcing.

This essay is an attempt to link real world observations (the failure of surface temperatures to rise in tandem with atmospheric CO2) to basic physics and thereby show why the radiative characteristics of Greenhouse Gases can not increase the surface temperature of a planet when atmospheric mass, the strength of the gravitational field and the power of insolation at the top of the atmosphere remain the same.

Different substances absorb different frequencies of IR, and the different parts of the planet differ wildly in how much IR is being emitted (based as it is on surface temperature) and how much cloud and water vapor there is at that location (carbon dioxide is very well mixed).

http://jupiter-information-site.weebly.com/jupiters-temperature.html «At the top of the atmosphere [Jupiter], temperatures can reach as high as 725 °C (1,340 °F), over 600 miles (1,000 kilometers) above the planet's surface.»

It looks likely that the rapid warming of the Arctic has broken the thermometer temperature record in two different ways - firstly by violating the assumption that unobserved regions of the planet warm at a broadly similar rate to observed regions, and secondly by violating the assumption that neighbouring regions of the planet's surface warm at a similar rate.

At the moment, Lindzen is pursuing a theory that says increased amounts of water vapor — from warming surface temperatures — will reduce heat - trapping high - cirrus clouds, which will help balance the planet's temperature.

So it's all gases at greatest density will be doing the same thing around the planet at the same time (*) and as these change with differences in density in the play between gravity and pressure and kinetic and potential from greatest near the surface to more rarified, less dense and absent any kinetic to write home about the higher one goes, then, energy conservation intact, the hotter will rise and cool because losing kinetic energy means losing temperature, thus cooling they which began with the closest in density and kinetic energy as a sort of band of brothers near the surface will rise and cool at the same time whereupon they'll all come down together colder but wiser that great heights don't make for more comfort and giving up their heat will sink displacing the hotter now in their place when they first went travelling.

So, without any external heat source and none from the planet all that's in play here is the heat this chilled out band of brothers gains on the way down, heavier and sinking gaining kinetic energy and therefore temperature the denser they get until finally at the surface becoming too hot they expand and rise slipping out of their restricting gravity and rude neighbours bumping into them they get themselves some space and cool off, then coming back off their high when they realise just how cold and lonely they are, getting nostalgic again for their noisy neighbours who won't stick to their side of the road, forgetting, we do forget just how horrible horrible past experiences were, that they'll just get all hot and bothered again.

Our neighboring planets, Venus and Mars, range the extremes in temperatures: the surface of Venus, at a temperature of 900ø F, is hot enough to melt lead, while during Martian nights the temperature drop to 220ø F below zero.

That lack of immediate concern may in part stem from a lack of understanding that today's pollution will heat the planet for centuries to come, as explained in this Denial101x lecture: So far humans have caused about 1 °C warming of global surface temperatures, but if we were to freeze the level of atmospheric carbon dioxide at today's levels, the planet would continue warming.

Planets with atmospheres stabilise their surface temperatures at a level dependent upon the density of the atmosphere leaving the main variation in planetary temperature dependent on variations in the energy coming in from the local star.

The planet is radiating at its temperature, and the surface of the shell is radiating at its temperature.

When you hear the term «global warming,» do you think of the warming of air temperatures at the Earth's surface, or the warming of the planet as a whole?

During the talk, I showed the following graph of the Earth's total heat content, demonstrating that even over the last decade when surface temperature warming has slowed somewhat, the planet continues to build up heat at a rate of 4 Hiroshima bomb detonations worth of heat every second.

At that thermal equilibrium the surface temperature can be calculated using the S - B Law for any planet at a given level of solar inpuAt that thermal equilibrium the surface temperature can be calculated using the S - B Law for any planet at a given level of solar inpuat a given level of solar input.

It will also include scientifically refuting the apparent falsification of the above «dangerous AGW» hypothesis, which has resulted from the observed «lack of warming» of our planet over the past decade (atmosphere, at both the surface and troposphere since 2001, sea surface temperature since ARGO measurements were installed in 2003), despite record increase in atmospheric CO2, as measured at Mauna Loa, by demonstrating with empirical data where the «missing energy» is hiding.

While the earths surface temperatures and oceans should be heating due to GHGs, there should also be some continuous super-long-term cooling happening when you look at the whole mass of the planet.

Our planet's surface is now kept at a comfortable temperature because the atmosphere traps some of the radiant heat from the Sun and keeps it near the surface, warming the planet and sustaining living creatures.

Working back from the clouds at a height of say 4kilometers and applying the adiabatic lapse rate of 9.8 K / km we arrive at the planet surface temperatures of around 15C.
